| Description | XWEB EVO before 5.6.2 contains a pre-authentication OS command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary commands by injecting shell metacharacters into the password field. Attackers can exploit the unescaped interpolation of the password value into the hashpass invocation within login.lua, cleanout.lua, and api.lua to achieve root-level command execution via the setuid wlua interpreter. This product line reached it's end of service date in March 2026. |
