CVE-2022-23972

Database read, modification, and deletion via SQL injection

Published Apr 7, 2022 · Updated Sep 16, 2024

SQL injection in ASUS RT-AX56U firmware 3.0.0.4.386.45898 allows remote attackers on the LAN to read, modify, or delete its database. The SQL-storage function accepts a user-controlled parameter without validation and incorporates it into database handling, permitting arbitrary SQL statements. Network adjacency is required, but no authentication is needed; successful exploitation exposes stored data to reading, alteration, and deletion.
