4DescriptionGitHub Advisory
Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions prior to 2.28.1 running on MySQL family databases are affected by an authentication bypass vulnerability in the SOAP API, as a result of an improper type checking on the password parameter. Other database backends are not affected, as they do not perform implicit type conversion from string to integer. Using a crafted SOAP envelope, an attacker knowing the victim's username is able to login to the SOAP API with their account without knowledge of the actual password, and execute any API function they have access to. Version 2.28.1 contains a patch. Disabling the SOAP API significantly reduces the risk, but still allows the attacker to retrieve user account information including email address and real name.
AnalysisAI
MantisBT versions prior to 2.28.1 contain an authentication bypass vulnerability in the SOAP API caused by improper type checking on the password parameter when running on MySQL family databases. An attacker who knows a victim's username can log in to the SOAP API without knowing the correct password and execute any API function available to that account. …

Vulnerability AssessmentAI
| Exploitation | MantisBT versions prior to 2.28.1 running on MySQL family databases with SOAP API enabled. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | While a CVSS vector and EPSS score are not currently available, the real-world risk is substantial based on several factors. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker discovers a MantisBT instance running version 2.27.0 on MySQL and enumerates a valid username (e.g., 'admin') through the web interface or public documentation. The attacker crafts a SOAP envelope containing the username and a maliciously formatted password parameter (e.g., a numeric value or boolean that causes MySQL type coercion to succeed). … |
| Remediation | Immediately upgrade MantisBT to version 2.28.1 or later to patch the authentication bypass vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
