Papercut Mf Ng
Monthly
Remote code execution affects PaperCut MF and PaperCut NG through unsafe dynamic class loading in the database connection utilities, which instantiate JDBC driver classes from configurable driver names without validating them against an allowlist. An attacker who can control administrative system configuration parameters can force the server to load and execute arbitrary Java bytecode already present on the application classpath, running with the full privileges of the PaperCut server process. No public exploit identified at time of analysis, but the PR:H requirement and PaperCut's history of being targeted make prompt patching advisable.
Improper access control (CWE-305) in the PaperCut MF and PaperCut NG web management interface allows unauthenticated remote attackers to trigger backend administrative operations before access validation completes, enabling unauthorized modification of system configurations. The CVSS 4.0 vector rates this AV:N/AC:L/PR:N/UI:N with high integrity impact, indicating network-exploitable, zero-authentication exploitation with no user interaction required. No public exploit code or CISA KEV listing has been identified at time of analysis, though PaperCut products have historically been high-value ransomware targets.
