CWE
- CWE-125 - Out-of-bounds Read
Summary
Open5GS 2.6.1 through 2.8.0 contains an out-of-bounds read vulnerability in parse_scheme_output() in lib/sbi/conv.c during SUCI de-concealment due to incomplete length validation. Remote unauthenticated UEs or SBI peers can submit a crafted SUCI with a 42-byte scheme output to a UDM, triggering a heap over-read past the buffer.

CWE
- CWE-787 - Out-of-bounds Write
Summary
Open5GS 1.3.0 through 2.8.0 contains a heap out-of-bounds write vulnerability in parse_multipart() that allows unauthenticated attackers to corrupt memory by supplying an empty multipart boundary. Attackers can send a single crafted multipart/related request to the SBI interface of any network function, overflowing the lookbehind buffer and crashing it.

CWE
- CWE-617 - Reachable Assertion
Summary
Open5GS through 2.8.0 contains a reachable assertion vulnerability in mme_gn_handle_sgsn_context_request() that allows remote unauthenticated attackers to crash the MME via malformed SGSN Address IEs. Attackers sending GTPv1-C traffic from a configured SGSN address with a known UE IMSI or P-TMSI can supply an invalid address length to terminate open5gs-mmed, denying service to all subscribers.

CWE
- CWE-125 - Out-of-bounds Read
Summary
Open5GS through 2.8.0 contains a heap out-of-bounds read vulnerability in ogs_pfcp_parse_volume_measurement() in lib/pfcp/types.c that allows remote unauthenticated attackers to read past IE buffers. Attackers can send a PFCP Session Report Request to the SMF on UDP port 8805 with a short, all-flags Volume Measurement IE, reading up to 48 bytes and potentially crashing the SMF.

CWE
- CWE-763 - Release of Invalid Pointer or Reference
Summary
Invalid pointer release vulnerability. Exploitation of this vulnerability could allow an attacker to interrupt the correct operation of the service by sending a specially crafted json string to the VNF (Virtual Network Function), and triggering the ogs_sbi_message_free function, which could cause a service outage.

Summary
Due to insufficient length validation in the Open5GS GTP library versions prior to versions 2.4.13 and 2.5.7, when parsing extension headers in GPRS tunneling protocol (GPTv1-U) messages, a protocol payload with any extension header length set to zero causes an infinite loop. The affected process becomes immediately unresponsive, resulting in denial of service and excessive resource consumption. CVSS3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C

CWE
- CWE-676 - Use of Potentially Dangerous Function
Summary
When Open5GS UPF receives a PFCP Session Establishment Request, it stores related values for building the PFCP Session Establishment Response. Once UPF receives a request, it gets the f_teid_len from incoming message, and then uses it to copy data from incoming message to struct f_teid without checking the maximum length. If the pdi.local_f_teid.len exceeds the maximum length of the struct of f_teid, the memcpy() overwrites the fields (e.g., f_teid_len) after f_teid in the pdr struct. After parsing the request, the UPF starts to build a response. The f_teid_len with its overwritten value is used as a length for memcpy(). A segmentation fault occurs, as a result of a memcpy(), if this overwritten value is large enough.
