Summary

CVE-2025-1127 is a critical-severity Path Traversal (CWE-22) vulnerability in Lexmark (inferred from references). Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-1127 is a critical vulnerability (CVSS score 9.1, CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) published on 2025-02-13, associated with CWE-22 (Path Traversal) and CWE-362 (Race Condition). It affects Lexmark products, as referenced in their security advisories. The flaw allows an attacker to execute arbitrary code as an unprivileged user and/or modify the contents of any data on the filesystem.

Exploitation requires high privileges (PR:H) and network access (AV:N) with low attack complexity and no user interaction. A privileged attacker can leverage this over the network to achieve arbitrary code execution running as an unprivileged user, alongside full filesystem modification capabilities, with changed scope (S:C) leading to high confidentiality, integrity, and availability impacts.

Lexmark's security advisories, available at https://www.lexmark.com/en_us/solutions/security/lexmark-security-advisories.html, provide details on mitigation and patches for this vulnerability.

Why these techniques?

Network-accessible path traversal/race condition in public-facing Lexmark device directly enables remote exploitation (T1190) leading to arbitrary code execution via command/shell interpreters (T1059.001) plus unrestricted filesystem writes.
