When this option is enabled, jobs can bypass the mandatory sentinel policies, creating a security loophole. This bypass can potentially allow unauthorized access to the system or data, leading to possible system compromise or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2394689503\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following pseudocode illustrates how this vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\"># Using Nomad job file with policy override option\nnomad job run -policy-override exploit.nomad<\/code><\/pre>\n<p>In this conceptual example, an attacker could craft a `exploit.nomad` job file with malicious intent, then use the `-policy-override` option to bypass the sentinel policies, potentially gaining unauthorized access to the system or data.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>It is highly recommended to apply the vendor-provided patches to mitigate this vulnerability. The patches for this vulnerability are present in the Nomad Enterprise versions 1.10.1, 1.9.9, and 1.8.13. If patching is not immediately possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report discusses a critical vulnerability, CVE-2025-3744, that affects Nomad Enterprise.
