Detailsinfo

A vulnerability, which was classified as critical, was found in Copeland XWEB EVO up to 5.8.8. Affected is some unknown processing of the file backup.lua of the component Backup. The manipulation of the argument output device path with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78.
