vulnerability

Adobe Campaign Classic (ACC) is affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. Exploit depends on conditions beyond the attacker's control. Exploitation of this issue does not require user interaction. Scope is changed.
