Title
Tenda CH7 Kylin Web Service CWebSessionManager_ParseSession entropy
Summary
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.
