ASUS RT-AX92U lighttpd mod_webdav.so SQL Injection Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected ASUS RT-AX92U routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mod_webdav.so module. When parsing a request, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose information in the context of root. Was ZDI-CAN-16078.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
