Attack-Flow Graph

Executive Summary

Adobe Campaign Classic has an Incorrect Authorization vulnerability allowing attackers to execute arbitrary code without user interaction. This occurs because the system fails to properly verify authorization before granting access.

Detection Guidance

Detection requires checking for unauthorized code execution attempts or unusual activity in Adobe Campaign Classic (ACC) logs. Monitor for unexpected user sessions or processes running with elevated privileges. Check network traffic for unusual outbound connections from ACC servers.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially stealing data, installing malware, or taking control of affected machines. Since no user interaction is needed, attacks can happen silently.

Compliance Impact

This vulnerability could lead to unauthorized access, data breaches, or loss of sensitive data, violating GDPR and HIPAA requirements for data protection and access controls.

Mitigation Strategies

Apply the latest security patches from Adobe immediately. Restrict network access to ACC servers to trusted IPs only. Disable unnecessary services or user accounts. Enable detailed logging and monitor for suspicious activity. Consider isolating ACC servers from critical systems until patched.
