CVE-2026-36618: n/a
The Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 discloses its DNS resolver software version (unbound 1. 22. 0) when responding to version. bind CHAOS TXT DNS queries. This information disclosure can aid attackers in crafting targeted attacks against known vulnerabilities in the disclosed software version. No patch or official remediation guidance is currently available. There is no evidence of active exploitation in the wild. The severity is assessed as low since the issue only reveals version information without direct exploitation capability.
AI Analysis
Technical Summary
This vulnerability involves the Mercusys AC12G (EU) V1 router firmware responding to version.bind CHAOS TXT DNS queries by revealing the DNS resolver software version (unbound 1.22.0). This version disclosure can assist attackers in identifying potential vulnerabilities specific to that software version for targeted attacks. No CVSS score or remediation information is provided, and no exploits are known to be active.
Potential Impact
The impact is limited to information disclosure of the DNS resolver software version. This could facilitate reconnaissance by attackers but does not directly enable exploitation or compromise. There is no indication of active exploitation or further impact beyond aiding targeted attacks.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting DNS queries that can elicit version information if possible.
