No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A security vulnerability has been detected in Tenda CH7, CH7G, CH10, CP3, CP3 Pro, CP7, TC3B14C, TC3B15C, TC3T14C and TC3T15C up to 20260625. Affected is the function CWebSessionManager_ParseSession of the file /user/bin/Kylin of the component Kylin Web Service. Such manipulation of the argument SESSION leads to insufficient entropy. The attack may be performed from remote. Attacks of this nature are highly complex. The exploitability is told to be difficult.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
