Severity2Low · CVSS 4.0
Exploitation probability0.33 %higher than 25% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

A flaw has been found in diem-project diem up to 5.1.3. The impacted element is the function dmOs::join of the file dmFrontPlugin/modules/dmCodeEditor/actions/actions.class.php of the component dmCodeEditor. Executing a manipulation can lead to path traversal. The attack can be launched remotely. The exploit has been published and may be used.

ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector AV:N con PR:H (privilegios altos) implica T1210; el path traversal en dmOs::join permite acceder a ficheros fuera del directorio previsto, aunque el texto no precisa si es lectura o escritura.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
