Description

In the web management interface of Archer AX72 (SG) v1, the network diagnostic feature improperly handles invalid user input, resulting in limited exposure of diagnostic command usage information. An authenticated attacker with administrative privileges could exploit this issue to confirm the presence of the diagnostic utility and view its valid command-line syntax and options. The exposed information is limited in scope and does not include sensitive system data.
