Link following vulnerability in the Uninstaller component in CCleaner prior to 7.10.1464 on Windows allows a local, low-privileged attacker to escalate privileges to SYSTEM via a symlink/junction created during application uninstallation, which CCleaner follows when deleting the application's data folder with elevated integrity.
AI Analysis
Technical Summary
This vulnerability (CWE-59) in CCleaner's Uninstaller component allows a local attacker with low privileges to create a symbolic link or junction that the uninstaller follows when deleting application data with elevated privileges. This improper link resolution can lead to privilege escalation to SYSTEM level. The issue affects CCleaner versions before 7.10.1464 on Windows. The CVSS v3.1 base score is 7.8, indicating high severity. No vendor advisory or patch information is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation allows a local attacker to escalate privileges from a low-privileged user to SYSTEM, potentially leading to full control over the affected system. This can compromise confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid running the uninstaller in environments where untrusted users can create symbolic links or junctions in the application's data folder path.
