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.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
