CVE-2013-5945Public exploitNetwork attack vector

Authentication bypass via unescaped password SQL interpolation

Published Feb 11, 2020 · Updated Aug 6, 2024

SQL injection in affected D-Link DSR router firmware allows remote attackers to bypass web authentication with a crafted password. The login.authenticate function and captivePortal.lua interpolate the unescaped Users.Password value into quoted SQL statements, letting injected predicates satisfy the login query. Access to the router's web interface is sufficient; no credentials are required, and successful exploitation grants administrative interface access.
