• → Protocol is UPnP; monitor for WLANConfiguration service actions (GetSecurityKeys / SetSecurityKeys) originating from unauthenticated/external sources. ↗

• · Affected firmware versions are V2.2.0_PK1.2T5, V2.2.0_PK1.2T2, V2.2.0_PK11T7, and V2.2.0_PK11T on ZTE ZXHN H168N; detections should be scoped to these versions. ↗
• · The exploit requires no authentication; access controls on the UPnP endpoint are entirely absent, meaning no credential-based detection is possible. ↗
• · The vendor advisory notes additional unexposed UPnP services beyond GetSecurityKeys/SetSecurityKeys are also affected; detection rules covering only these two actions may miss related abuse. ↗
