Detection & IOCs extracted from sources · hover to see the quote

command execute restore src-vis↗

• → Monitor for use of the 'execute restore src-vis' CLI command on FortiOS devices, particularly when invoked by local authenticated users, as it can be abused to download arbitrary files via specially crafted update packages. ↗
• → Inspect update packages supplied to the 'execute restore src-vis' command for unexpected or unauthorized content, as the command performs no integrity checking on downloaded code. ↗

• · Vulnerability only affects FortiOS versions before 7.0.3; devices running 7.0.3 or later are not affected. ↗
• · Exploitation requires local authenticated access; this is not a remote unauthenticated attack vector. CVSS score is 3.3 (Low). ↗
