Tenda AC7 V1.0 V15.03.06.44, Tenda AC9 V3.0 V15.03.06.42multi, and Tenda AC5 V1.0RTLV15.03.06.28 were discovered to contain a stack overflow via parameter page at url /goform/NatStaticSetting.

A weakness has been identified in Tenda AC9 15.03.06.42multi. Affected is the function formGetDdosDefenceList. This manipulation of the argument security.ddos.map causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.
