Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-1882 is a high-severity Improper Neutralization of Equivalent Special Elements (CWE-76) vulnerability in Papercut Papercut Mf. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 28% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-1882 is a remote code execution vulnerability affecting the PaperCut NG/MF application server. It stems from improper handling of a malicious payload that an authenticated administrator can create, as indicated by the associated CWEs including CWE-76. The flaw carries a CVSS 3.1 score of 7.2 with network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
An already authenticated admin user can supply the crafted payload to execute arbitrary code on the server hosting the PaperCut application. This requires administrative credentials but no user interaction, allowing the attacker to fully compromise the server once the payload is processed.
The vendor has published a security bulletin detailing the issue at the referenced URL. The EPSS score rose materially from a low baseline to a peak of 0.0916 on 2025-12-11 before receding to the current value of 0.0135, indicating that exploitation interest emerged after disclosure.

SA-11 requires developer testing and evaluation that can discover failures to neutralize equivalent special elements.
SI-10 requires validation of information inputs, directly stopping incomplete neutralization of equivalent special elements.
SA-8 mandates security engineering principles such as complete input validation and sanitization that cover equivalent special-element forms.

Secure SDLC practices directly require consistent neutralization of all equivalent special elements during input validation and sanitization.

A.8.25 mandates secure SDLC practices (secure coding guidelines, security requirements, checkpoints, testing, developer training) that reach improper neutralization of equivalent special elements, but only as one slice of a broad requirement whose implementation scope and rigour are left to the organisation.
Application security requirements include rules for handling special characters and equivalent encodings.
A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, distrust external input, fail securely, hardening, design review against attack patterns) that reach some but not most cases of equivalent-special-element neutralization failures.
Secure coding standards directly address proper neutralization of all equivalent special elements.
Security testing can detect incomplete neutralization but does not prevent the weakness itself.
