CVE-2023-1314

What is CVE-2023-1314?

A vulnerability has been identified in the Windows 32-bit installer for Cloudflare's cloudflared that allows local attackers to escalate their privileges without needing administrative access. This issue arises from the use of a world-writable directory by the MSI installer. Attackers with local access can exploit this flaw by creating symbolic links to mislead the installer into deleting or altering target files. This manipulation can occur during the repair process, posing a significant risk of system file deletion or replacement with malicious files, thereby compromising the affected device.
