EPSS: 0.4% probability of exploitation in the next 30 days

Weakness: CWE-59

Description

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.
