ASUS Router firmware: OS command injection via CSRF
Summary
Certain ASUS routers running firmware of the 3.0.0.6.102 series contain an OS command injection flaw (CWE-78) combined with a Cross-Site Request Forgery weakness (CWE-352). An attacker can lure a logged-in administrator to a phishing website, which causes the router to execute arbitrary commands with root privileges. The attack requires an active administrator session and a user click, but the impact includes full control over the router and the network behind it.
Affected
- ASUS routers on the 3.0.0.6.102 firmware series (specific models not published by ASUS in the sources reviewed)
- Default configuration is listed as unaffected in the CVE record; affected versions are as per the CNA record
Fixed in
- ASUS released a firmware update on 23 October 2026 for the 3.0.0.6.102 series
- Fixed build numbers: Unknown.
Workaround
- Unknown beyond firmware update.
- Do not browse other websites while logged in to the router admin page until the router is patched.
- Restrict administration to the LAN and disable remote (WAN) administration.
Exploitation
- No exploitation in the wild reported; CISA KEV: not listed.
- No public proof-of-concept found in the sources reviewed; absence of evidence is not proof that none exists.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Treat as high priority for any ASUS router on 3.0.0.6.102 firmware.
- Check the installed firmware version in the router admin interface and update using the ASUS support page for your model.
- Verify the fix against the ASUS Security Advisory directly, as its content could not be retrieved for this entry.
- Ensure the admin interface is not reachable from the internet.
- Fix the related CVE-2026-75775 and CVE-2026-93489 in the same update cycle.
- Log out of the router admin page after configuration changes.
