Papercut Mf ≤ 20.1.10
Raw vector
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-1223 is a medium-severity Exposure of Data Element to Wrong Session (CWE-488) vulnerability in Papercut Papercut Mf. Its CVSS base score is 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Vulnerability Data
This vulnerability potentially allows unauthorized enumeration of information from the embedded device APIs. An attacker must already have existing knowledge of some combination of valid usernames, device names and an internal system key. For such an attack to be successful…

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 enforces access decisions that can be scoped to the correct session context.
AC-4 controls information flows between entities, reducing cross-session leakage.
SC-4 directly stops unintended transfer of data through shared resources that different sessions may access.
SC-39 isolates execution domains so one session cannot reach another's state or data.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing authorization policies and least privilege can prevent cross-session data exposure when session separation is treated as an access rule.
Protecting data-in-use directly addresses runtime leakage of session data to unauthorized contexts.
Logical access controls and segmentation can be applied to isolate session state within applications or environments.

Secure development lifecycle practices include session-management controls that prevent exposure of data to the wrong session.
Application security requirements explicitly call for proper session isolation and state management.
A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, default-deny, fail-securely, distrust-external-input, zero-trust never-trust/always-verify, session control, data validation/sanitization, and explicit boundary enforcement across architecture layers) that directly stop session data from crossing to the wrong session; the bounded remainder is implementation defects that slip past even a well-applied review against known attack patterns.
Secure coding standards mandate correct session handling to prevent exposure of data elements to the wrong session.
Security testing can detect the weakness but does not itself implement the preventive control.
