An arbitrary file deletion vulnerability exists in PaperCut NG/MF, specifically affecting Windows servers with Web Print enabled. To exploit this vulnerability, an attacker must first obtain local login access to the Windows Server hosting PaperCut NG/MF and be capable of executing low-privilege code directly on the server.

Important: In most installations, this risk is mitigated by the default Windows Server configuration, which typically restricts local login access to Administrators only. However, this vulnerability could pose a risk to customers who allow non-administrative users to log in to the local console of the Windows environment hosting the PaperCut NG/MF application server.

Note: This CVE has been split into two separate CVEs (CVE-2024-3037 and CVE-2024-8404) and it’s been rescored with a Privileges Required (PR) rating of low, and “Attack Complexity (AC)” rating of low, reflecting the worst-case scenario where an Administrator has granted local login access to standard users on the host server.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
