Title
Ghost 0.7.2 before 6.64.0 Password Hash Ordering Disclosure via Admin API
Summary
Ghost from 0.7.2 before 6.64.0 contains an information disclosure vulnerability in the Admin API that allows staff-level users to determine the relative ordering of other staff users' password hashes. Authenticated staff users can query the Admin API to infer hash ordering, though this does not directly reveal hashes or enable practical password recovery.

Title
Ghost 5.42.2 before 6.58.0 Password Hash Disclosure
Summary
Ghost 5.42.2 before 6.58.0 contains an information disclosure vulnerability in the Admin API bulk post and page edit and delete endpoints, which accept filters on restricted fields such as authors.password, because of an incomplete fix for CVE-2026-70590. Staff-level attackers can infer other staff users' password hashes from which filters match and perform offline password-guessing attacks against them.

Title
OpenEMR: Username Enumeration via Pre-Authentication User Settings Loading
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. From 6.0.0 until 8.3.0, interface/globals.php uses the unauthenticated authUser login parameter to populate temp_authuserid and load that account's user_settings before authentication succeeds. Existing usernames can therefore cause an additional database query and may apply visible customized settings, while nonexistent usernames skip that behavior. A remote unauthenticated actor can use timing or page differences to enumerate valid accounts for later credential attacks. This issue is fixed in version 8.3.0.

Title
dgtlmoon changedetection.io Hash Comparison flask_app.py check_password timing discrepancy
Summary
A flaw has been found in dgtlmoon changedetection.io up to 0.60.7. The affected element is the function check_password of the file changedetectionio/flask_app.py of the component Hash Comparison. This manipulation of the argument Password causes observable timing discrepancy. The attack is possible to be carried out remotely. A high degree of complexity is needed for the attack. The exploitability is described as difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Title
Busybox: busybox: httpd user existence oracle in non-default shadow-disabled builds
Summary
A flaw was found in BusyBox's httpd web server. When configured with system password authentication, a user existence oracle may exist in certain build configurations. An attacker could distinguish existing from non-existing usernames by observing authentication failure behavior. Impact is limited to username enumeration and requires non-default compile options or uncommon password file states; default BusyBox builds with shadow password support are not affected.

Title
Zammad: Missing rate limiting allows password brute-forcing during two-factor login
Summary
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, the two-factor login step let an attacker try unlimited password guesses for any account without triggering Zammad's normal lockout or rate limiting. The response also revealed whether a guess was correct, even before two-factor authentication was checked. This made it possible to brute-force weak or reused passwords. This issue is fixed in version 7.1.2.

Title
WatchGuard Dimension Web UI Authentication Brute-Force Due to Missing Rate Limiting
Summary
WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts. If the account lockout setting is enabled, brute-force attempts are blocked after a defined number of failed attempts, but this setting is not enabled by default.

Mitigation MIT-46
Architecture and Design
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation MIT-39
Implementation
- Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
- If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
- Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
CAPEC-189: Black Box Reverse Engineering
An adversary discovers the structure, function, and composition of a type of computer software through black box analysis techniques. 'Black Box' methods involve interacting with the software indirectly, in the absence of direct access to the executable object. Such analysis typically involves interacting with the software at the boundaries of where the software interfaces with a larger execution environment, such as input-output vectors, libraries, or APIs. Black Box Reverse Engineering also refers to gathering physical side effects of a hardware device, such as electromagnetic radiation or sounds.
