Technical details

An insecure deserialization vulnerability (CWE-502) exists in N-able N-central prior to version 2025.3.1. The flaw stems from the application improperly processing untrusted data, which can be manipulated to execute arbitrary code. While some assessments suggest a local attack vector, the vendor-provided CVSS 4.0 score indicates the vulnerability is network-reachable (AV:N) but requires low-level authenticated privileges (PR:L). Successful exploitation allows for full compromise of confidentiality, integrity, and availability (H/H/H). CISA has confirmed active exploitation of this vulnerability, and users are urged to update to version 2025.3.1 or later.
