1. Introduction
Adobe Creative Cloud Desktop is affected by an arbitrary code execution vulnerability (APSB22-11). This means a local attacker could run malicious code on systems with vulnerable versions of the installer. This impacts confidentiality, integrity and availability. Systems running Adobe Creative Cloud Desktop version 2.7.0.13 or earlier are at risk.
2. Technical Explanation
- Root cause: Insufficient validation of installation parameters allows an attacker to inject malicious commands.
- Exploit mechanism: An attacker could modify the installer and then execute it, triggering code execution. For example, they might replace legitimate files with a script that creates a backdoor.
- Scope: Affected platforms include Windows and macOS systems running Adobe Creative Cloud Desktop 2.7.0.13 or earlier.
3. Detection and Assessment
You can check if your system is vulnerable by verifying the installed version of Adobe Creative Cloud Desktop. A thorough method involves checking file integrity.
- Quick checks: Run the application and navigate to Help > About Adobe Creative Cloud. Note the version number.
- Scanning: Nessus vulnerability ID 168349 can detect this issue based on self-reported version numbers. This is an example only, as it relies on accurate reporting by the application.
- Logs and evidence: There are no specific log files or event IDs directly indicating exploitation of this vulnerability. However, unusual processes launched from the Adobe Creative Cloud Desktop installation directory may indicate compromise.
