mJobtime 15.7.2 handles authorization on the client side, which allows an attacker to modify the client-side code and gain access to administrative features. Additionally, they can craft requests based on the client-side code to call these administrative functions directly.

A blind SQL Injection (SQLi) vulnerability in mJobtime v15.7.2 allows unauthenticated attackers to execute arbitrary SQL statements via a crafted POST request to the /Default.aspx/updateprofileServer endpoint .

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 exportSqlQueryServer 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 xpcmdshell and xpreadfile, achieving pre-authentication remote code execution as LocalSystem via a single HTTP request.
