What to do

AI-suggested

  1. Upgrade Malwarebytes AdwCleaner to version 8.7.0 or later where this vulnerability is fixed.
  2. Until patching is possible, restrict local user permissions to prevent unauthorized file creation in the folders targeted by AdwCleaner’s log deletion process.
  3. Implement application whitelisting and endpoint protection to detect and block suspicious symbolic link creation or manipulation.
  4. Monitor file system activity for unusual symlink creation or deletion operations in directories used by AdwCleaner.
  5. Use Group Policy or endpoint management tools to enforce least privilege principles and limit administrative rights on endpoints.
  6. Educate users about the risks of local privilege escalation and enforce strict access controls on shared machines.
  7. Regularly audit installed software versions and patch management processes to ensure timely updates of security-critical applications.

Description

Malwarebytes AdwCleaner before v.8.7.0 runs as Administrator and performs an insecure log file delete operation in which the target location is user-controllable, allowing a non-admin user to escalate privileges to SYSTEM via a symbolic link, a related issue to CVE-2023-28892. To exploit this, an attacker must create a file in a given folder path and intercept the application log file deletion flow.
