ASUS Router Models Remote Code and Disclosure Flaws

Remote command execution in certain ASUS router firmware allows a network man-in-the-middle attacker to force the router to download and run arbitrary commands from a spoofed update/download server. The root cause is a failure to validate both the integrity check value (CWE-354) and the TLS server certificate, so an attacker positioned in the network path can impersonate a legitimate ASUS server. No public exploit identified at time of analysis and the flaw is not in CISA KEV; ASUS self-reported it and rates it critical (CVSS 4.0 9.5), though exploitation requires the attacker to first achieve a MITM position (AT:P).

SQL injection in the web management interface of multiple ASUS router models enables a remotely authenticated, high-privilege user to exfiltrate confidential information by sending crafted requests that bypass the router's existing input validation. The vulnerability is limited to read-only data disclosure (no integrity or availability impact) and requires prior administrative authentication, significantly constraining real-world exploitability. No public exploit code or CISA KEV listing has been identified at time of analysis; the CVSS 4.0 score of 5.9 reflects the high complexity and authentication prerequisites.
