| Title | qiyuesuo electronic signature platform <=4.34 Scheduled task RCE |
|---|
| Description | In this exploit, the attacker used the platform's scheduled task feature to upload custom Java class files and bypassed the Runtime/Process blacklist detection mechanism by concatenating strings and using reflection. Ultimately, the attacker successfully executed system commands on the server side, completing remote command execution (RCE). |
