CVE-2026-95701

MISP Path Traversal via Organization Name in Org-Statistics Logo Check

Published Sep 22, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Solution

The fix corrects the logo directory path from the obsolete app/webroot/img/orgs to the current files/img/orgs location, expands the lookup to cover id, name, and uuid fields across png and svg extensions (mirroring the getOrgLogo helper), and adds a security guard: the candidate path is resolved with realpath() and verified via str_starts_with() against the resolved base directory, so any organization name containing traversal sequences (../) that would resolve outside files/img/orgs is rejected.
