- CWE-295 - Improper Certificate Validation
Summary
The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites.
Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

CWE
- CWE-250 - Execution with Unnecessary Privileges
Summary
The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`)
that scans container processes for runtime fingerprinting. When scanning a
container, the coordinator:
1. **fork()s** a child process
2. **setns()** into the target container's PID and mount namespaces
3. **fchdir()** back to an orphaned FD pointing at the extractor's own root
filesystem (where `/crio.sock` is hostPath-mounted)
4. Calls **only `seteuid(target_uid)`** — changing the effective UID but leaving
the **real UID and saved-set-UID at 0** and **retaining the permitted
capability set**
5. The `check_no_privileged_perms()` guard inspects only the Effective capability
set (so it passes), and is **skipped entirely when the target runs as uid 0**
6. The `VersionExecutable` fingerprint invokes `fpr_kind_executable` with
`process.command_line[0]` — the target's argv[0], read from
`/proc/<pid>/cmdline` and **fully controlled by the workload**
7. `fpr_kind_executable` calls `exec.Command(executable, "--version").Output()`
— executing the **workload's own binary** inside the workload's mount
namespace while **ruid=0 in the host user namespace**
The executed process can call `setuid(0)` to restore full root with
`CAP_SYS_ADMIN`, and inherits the orphaned cwd which resolves into the extractor
container's filesystem containing the host CRI-O socket.
## Affected Code
### 1. Insufficient privilege drop (Rust — extractor coordinator)
**File:** `extractor/src/insights_runtime_extractor.rs`
```rust
// Lines 139-146 — seteuid-only drop, guard skipped for root containers
join_process_namespaces(process.pid)?;
change_dir(current_dir);
switch_user(*process.uid)?;
if *process.uid != 0 {
perms::check_no_privileged_perms()
.expect("Must not have privileged permissions to run fingerprints");
}
fingerprint::run_fingerprints(&config, out_dir, &process);
```
```rust
// Lines 182-185 — only effective UID changed; ruid/suid stay 0
fn switch_user(uid: u32) -> Result<(), ScannerError> {
debug!("... Becoming user: {uid}");
seteuid(uid.into()).map_err(|e| ScannerError::Errno(e))
}
```
### 2. Execution of untrusted binary (Go — fingerprint)
**File:** `fingerprints/pkg/utils/file.go`
```go
// Lines 75-80 — executes a path taken verbatim from workload's argv[0]
func GetExecutableVersionOutput(executable string) (string, error) {
out, err := exec.Command(executable, "--version").Output()
if err != nil {
return "", err
}
return string(out), nil
}
```
### 3. Workload-controlled path forwarded (Rust — version_executable)
**File:** `version_executable.rs`
```rust
// Lines 29-34 — workload-controlled command_line[0] forwarded to fingerprint
return Some(vec![
fpr_kind_executable,
out_dir.to_string(),
String::from(&process.command_line[0]),
String::from(&version_executable.runtime_kind_name),
]);
```
## Attack Pattern
**Attacker:** Any tenant able to schedule a pod (unprivileged, any namespace)
**Victim:** The node running the insights-runtime-extractor DaemonSet
**Trigger:** Automatic — the DaemonSet scans all container processes on the node
**Attack sequence:**
1. Attacker creates a pod whose process name matches a configured
versioned-executable pattern (`node`, `python`, `python3`, `MainThread`,
or contains `java`)
2. The pod's main binary (at the path matching argv[0]) is a malicious
executable that calls `setuid(0)` to restore root
3. When the insights operator triggers a scan, the DaemonSet forks, enters the
attacker's mount namespace, and executes the attacker's binary with ruid=0
4. The attacker's code regains full root with `CAP_SYS_ADMIN` in the host user
namespace
5. The inherited cwd contains the host CRI-O socket → full node compromise

CWE
- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster.

- CWE-269 - Improper Privilege Management
Summary
The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster.
Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373
```
- apiGroups:
- ""
resources:
- secrets
verbs:
- get
- list
```
By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace.
```
spec:
serviceAccountName:"gather"
```

CWE
- CWE-306 - Missing Authentication for Critical Function
Summary
A flaw was found in oc-mirror. During mirroring operations, the embedded local cache registry binds to all network interfaces without authentication or encryption instead of restricting access to the local system. An unauthenticated attacker on an adjacent network can connect to the exposed service to push tampered container images, delete cached images, or access mirrored content.

- CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
Summary
A flaw was found in oauth-proxy. The application fails to properly validate the destination redirect parameter (`rd`) during post-login redirection. A remote attacker can exploit this vulnerability by enticing a user to follow a specially crafted link, resulting in the user being redirected to an arbitrary external website after authenticating. This open redirect can be leveraged to conduct phishing attacks or credential theft.

- CWE-829 - Inclusion of Functionality from Untrusted Control Sphere
Summary
A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
A flaw was found in the OpenShift console. An unauthenticated attacker can exploit a path traversal vulnerability by manipulating the `lng` and `ns` query parameters in the `/locales/resource.json` endpoint. This allows the attacker to read sensitive `*.json` files from the pod filesystem, including plugin manifests and configuration files. Furthermore, this flaw can enable path traversal against registered dynamic-plugin backends.

Summary
A flaw was found in openshift/console. An unauthenticated remote attacker can exploit a misconfiguration in the CatalogdHandler, which lacks proper authentication, and the forwarding of the `openshift-session-token` cookie. This allows the attacker to send requests to the in-cluster catalogd service, leading to the disclosure of the internal operator-catalog index and providing a relay into the openshift-catalogd namespace.

CWE
- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
A flaw was found in the OpenShift console. Unauthenticated access to the `/api/devfile/` and `/api/devfile/samples/` endpoints allows a remote attacker to send crafted devfile payloads. This can lead to Server-Side Request Forgery (SSRF), where the console pod makes requests to internal services and reflects partial responses to the attacker. Additionally, by sending repeated large requests without a specified content length, an attacker can cause unbounded memory growth, leading to a Denial of Service (DoS).

- CWE-407 - Inefficient Algorithmic Complexity
Summary
A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.

Rate-limit unauthenticated requests to the OAuth login and error endpoints as an additional defense. The proxy must re-establish TLS to the existing OAuth route, preserve the OAuth hostname/SNI, and validate the backend certificate. Do not disable TLS verification or expose the OAuth service directly. If an external TLS-terminating control cannot be deployed, there is no supported OpenShift router-only mitigation while the OAuth route remains TLS passthrough. Restricting access to the OAuth endpoint to trusted networks can reduce exposure but may affect user access. Upgrade to the first OpenShift release containing the fix as soon as it is available."

- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
A Server-Side Request Forgery and supply chain flaw was found in the OpenShift Console Helm catalog proxy. A namespace tenant can plant a ProjectHelmChartRepository with an arbitrary URL that the console pod fetches server-side, bypassing tenant egress restrictions. Combined with catalog metadata poisoning and admin-mediated chart installation, this enables privilege escalation.

Summary
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.

Summary
A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected.

Summary
A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys (X-Forwarded-User) but does not strip underscore-variant keys (X_Forwarded_User) from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing an authenticated low-privilege user to smuggle a forged identity that may override the legitimate authenticated identity in the upstream application.

- CWE-306 - Missing Authentication for Critical Function
Summary
A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.

Summary
A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.

CWE
- CWE-23 - Relative Path Traversal
Summary
A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.

The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass."

Summary
A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.

- CWE-415 - Double Free
Summary
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.

CWE
- CWE-88 - Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')
Summary
A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field. This allows arbitrary code execution on the machine of a user who installs the role via ansible-galaxy role install.

- CWE-918 - Server-Side Request Forgery (SSRF)
Summary
A flaw was found in the OpenShift Router. A user with EndpointSlice write access can exploit this vulnerability by creating a Service backed by an FQDN (Fully Qualified Domain Name) EndpointSlice that resolves to a cloud metadata endpoint. This allows the router to proxy requests to the cloud metadata endpoint, leading to the disclosure of instance credentials and other sensitive metadata. This bypasses previous security measures for validating IP addresses.

CWE
- CWE-287 - Improper Authentication
Summary
A flaw was found in the OpenShift Router. When a Route has `insecureEdgeTerminationPolicy` set to Allow, the HTTP frontend does not remove `X-SSL-Client-*` headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted `X-SSL-Client-*` headers. As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.

Summary
A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service.

If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the \"check password script\" is used with %u and the samba-dcerpcd service is started as a system service."

This vulnerability allows an attacker to achieve remote command execution on the affected system.

Summary
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.

CWE
- CWE-475 - Undefined Behavior for Input to API
Summary
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers.

- CWE-170 - Improper Null Termination
Summary
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
