Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for ASUS/DSL-AC51, ASUS/DSL-AC52, ASUS/DSL-AC52U.
  2. 2Review the reported fix. Source-reported solution: Update following models to version 1.1.2.3_792 or later： DSL-N17U, DSL-N55U_C1, DSL-N55U_D1, DSL-N66U Update following models to version 1.1.2.3_807 or later： DSL-N12U_C1, DSL-N12U_D1, DSL-N14U, DSL-N14U_B1 Update following models to version 1.1.2.3_999 or later： DSL-N16, DSL-AC51, DSL-AC750, DSL-AC52U, DSL-AC55U, DSL-AC56U The following models are no longer maintained, and it is recommended to retire and replace them. DSL-N10_C1, DSL-N10_D1, DSL-N10P_C1, DSL-N12E_C1, ,DSL-N16P, DSL-N16U, DSL-AC52, DSL-AC55 If replacement is not possible in the short term, it is recommended to disable remote access (Web access from WAN), virtual servers (Port forwarding), DDNS, VPN server, DMZ, and port trigger.
