A Permissive Cross-domain Security Policy with Untrusted Domains in Armoury Crate allows a remote user to obtain a local user's NTLM hash by convincing the user to visit a crafted web page that sends a request containing a UNC path to the application's local service endpoint.Refer to the ' Security Update for Armoury Crate App ' section on the ASUS Security Advisory for more information.

Remediation
The vendor's own words where we have them.
Upgrade Armoury Crate to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Prioritize based on EPSS, PoC availability, and external exposure.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

What this weakness leads to
MITRE's own consequences and mitigations for the weakness class — the authority's wording, not guidance derived from the CVSS vector.
CWE-942 · Permissive Cross-domain Policy with Untrusted Domains
- Execute Unauthorized Code or Commands
- Bypass Protection Mechanism
- Read Application Data
- Varies by Context
Mitigation: Avoid using wildcards in the cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.

Detection
Read off the CVSS vector and the weakness class. Starting points, not rules we have tested.
- Prioritize edge telemetry for network-reachable Armoury Crate.
- Monitor for scanner or exploit-pattern traffic after 4 public PoC repositories were reported.

Answered from this record1
What should defenders know first?
CVE-2026-12962 is A Permissive Cross-domain Security Policy with Untrusted Domains in Armoury Crate allows a remote user to obtain a local user's NTLM hash…, a medium vulnerability affecting Armoury Crate from ASUS. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-12962. Public exploit evidence is: 4 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 5.3 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
