Detailsinfo

A vulnerability classified as problematic was found in MISP up to 2.5.46. Affected by this vulnerability is the function __statisticsOrgs of the file UsersController.php of the component Logo Handler. The manipulation of the argument k with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality. The summary by CVE is:

In MISP, the __statisticsOrgs method in UsersController.php used the organization name directly as a file-system path component when checking for the existence of an organization logo image. The original code called file_exists() with a path constructed as APP . 'webroot' . DS . 'img' . DS . 'orgs' . DS . $k . '.png', where $k is the organization name. Because the referenced directory (app/webroot/img/orgs) no longer exists in current MISP deployments (org logos were relocated to files/img/orgs), the check was functionally dead and never triggered. However, the underlying pattern—concatenating an attacker-influenced organization name into a file path without sanitization—constitutes a path traversal weakness. An organization name containing directory traversal sequences (e.g., '../../../../etc/passwd') would, if the target directory existed, allow an authenticated user with the ability to create or rename an organization to probe for the existence of arbitrary files on the server.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-95701 since 09/22/2026. The exploitation appears to be easy. The attack can be launched remotely. Additional levels of successful authentication are required for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
