Detailsinfo

A vulnerability, which was classified as critical, was found in Dancer up to 1.3399. Affected is the function read_session_id. The manipulation of the argument session_id with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Dancer versions before 1.3400 for Perl pass unvalidated session ids from the session cookie to the session engine. read_session_id returns the cookie value as the session id without checking its characters, and Dancer hands it to the session engine to load the session. A remote attacker may cause path traversal or injection in a session engine that uses the id in a file path, cache command or query without checking it.

The advisory is available at github.com. This vulnerability is traded as CVE-2015-10149 since 11/14/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.
