Progress WS_FTP Server Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Published Oct 9, 2023 · corrected/updated Oct 9, 2023 · Progress WS_FTP Server · evidence confidence very high
In WS_FTP Server versions prior to 8.7.4 and 8.8.2, a directory traversal vulnerability was discovered. An attacker could leverage this vulnerability to perform file operations (delete, rename, rmdir, mkdir) on files and folders outside of their authorized WS_FTP folder path. Attackers could also escape the context of the WS_FTP Server file structure and perform the same level of operations (delete, rename, rmdir, mkdir) on file and folder locations on the underlying operating system.
