Detection & IOCsextracted from sources · hover to see the quote
- →Target device is ASUS RT-AX55 router; look for authenticated POST requests to /start_apply.htm with a manipulated qos_bw_rulelist parameter containing OS command injection payloads ↗
- →CVE-2023-41346 specifically relates to the 'token-refresh module' on ASUS RT-AX55 devices; monitor for anomalous use of the token-refresh functionality by authenticated sessions ↗
- →Flag remote authenticated requests to ASUS RT-AX55 routers that result in unexpected OS command execution; exploitation requires authentication but can lead to arbitrary command execution ↗
- ·Exploitation requires prior authentication; unauthenticated attackers cannot directly trigger this vulnerability. Detection should focus on authenticated sessions exhibiting injection patterns. ↗
- ·The CVE-2023-41346 'token-refresh module' issue is one of a family of four related OS command injection vulnerabilities on the same device (CVE-2023-41345, CVE-2023-41346, CVE-2023-41347, CVE-2023-41348); all should be patched together. ↗
- ·Affected firmware version confirmed as 3.0.0.4.386.51598 on ASUS RT-AX55; verify firmware version before applying detections to avoid false positives on patched devices. ↗
