AI Analysis
Technical Summary
The Mercusys AC12G (EU) V1 router firmware version AC12G(EU)_V1_200909 contains an undocumented endpoint (/agileconfigreset) that returns internal buffer contents to unauthenticated attackers on the adjacent network. This information disclosure vulnerability is classified under CWE-200 and has a CVSS 3.1 base score of 4.3, reflecting low attack complexity and no required privileges or user interaction. There is no known patch or vendor advisory specifying remediation at this time.
Potential Impact
An attacker on the adjacent network can access internal buffer contents via the undocumented /agileconfigreset endpoint without authentication. This leads to partial confidentiality loss of internal data. There is no impact on integrity or availability reported. No known exploits are currently in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit network access to the device from untrusted adjacent networks to reduce exposure.
