Description
mJobTime through build 15.7.3.32 contains an unauthenticated SQL execution vulnerability in the Login.aspx admin panel handlers, where the runQueryButton postback and exportSqlQuery_Server PageMethod execute caller-supplied SQL against the backing Sybase SQL Anywhere database using DBA/sysadmin privileges with no server-side authentication enforced beyond a client-side sessionStorage flag. Attackers can submit arbitrary SQL through these exposed endpoints to invoke xp_cmdshell and xp_read_file, achieving pre-authentication remote code execution as LocalSystem via a single HTTP request.
