Detailsinfo

A vulnerability was found in IBM AIX and VIOS (affected version not known) and classified as critical. This issue affects some unknown functionality of the component NIM Server. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is integrity, and availability. The summary by CVE is:

IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 NIM server (formerly known as NIM master) service (nimesis) could allow a remote attacker to traverse directories on the system. An attacker could send a specially crafted URL request to write arbitrary files on the system.

It is possible to read the advisory at ibm.com. The identification of this vulnerability is CVE-2025-36236 since 04/15/2025. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/20/2025). The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.
