Summary

CVE-2025-11366 is a critical-severity Path Traversal (CWE-22) vulnerability in N-Able N-Central. Its CVSS base score is 9.4 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38.9th 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-2025-11366 is a critical authentication bypass vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) affecting N-central versions prior to 2025.4. The issue stems from path traversal (CWE-22), enabling attackers to circumvent authentication mechanisms by manipulating file paths in requests.

Remote attackers with network access can exploit this vulnerability without authentication privileges or user interaction. Successful exploitation provides high-impact access, allowing unauthorized disclosure of sensitive data (C:H), modification of systems or data (I:H), and disruption of services (A:H).

The N-able security advisory at https://me.n-able.com/s/security-advisory/aArVy0000000rcDKAQ/cve202511366-ncentral-authentication-bypass-via-path-traversal provides details on mitigation, including upgrading to N-central 2025.4 or later to address the path traversal flaw.
