Detailsinfo

A vulnerability, which was classified as critical, was found in South River MFT Server and Titan SFTP Server on Linux (SSH Server Software) (affected version unknown). Affected is an unknown functionality of the component SIZE Command Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
