Archer Ax55 V4
Monthly
Stack-based buffer overflow in the EasyMesh daemon of the TP-Link Archer AX55 v4 allows a LAN-adjacent unauthenticated attacker to crash the easymesh process and potentially achieve remote code execution on the router, provided Mesh mode is enabled. The CVSS 4.0 vector (AV:A/AC:H/AT:P/PR:N) correctly constrains the attack to the local network segment with high complexity due to the Mesh mode prerequisite. TP-Link has released a patched firmware; no public exploit code or active exploitation has been identified at time of analysis.
Hard-coded RSA private key exposure in the TP-Link Archer AX55 v4 web module allows a LAN-adjacent attacker who captures HTTP login traffic to decrypt the administrator password, since the shared private key is identical across all units of this model and the AES session key is additionally weakened. All Archer AX55 v4 firmware versions appear affected per the CPE wildcard, with a vendor patch now available via TP-Link's firmware portal. No public exploit code has been identified at time of analysis, though the cryptographic flaw is deterministic - once the static key is extracted from firmware, any captured login session can be decrypted offline.
