Detailsinfo

A vulnerability classified as critical has been found in libssh (affected version not known). Affected is some unknown functionality of the component Path Handler. The manipulation 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:

A malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This is the same issue as in OpenSSH, tracked as CVE-2019-6111.

The advisory is available at bugzilla.redhat.com. This vulnerability is traded as CVE-2026-0964. The exploitability is told to be difficult. It is possible to launch the attack remotely.
