CVE-2026-113802
CriticalCVSS 9.8Summary
Wavlink WL-WN530BE1-A firmware through M30BE1_V251117 contains an OS command injection vulnerability in the sub_23B54 function of the ioos binary, which passes the unsanitized file_id parameter of /protocol.csp?opt=ovpn_file requests with type=del to popen(). A remote unauthenticated attacker can send a forged IP-FROM: 127.0.0.1 header to bypass login and execute arbitrary commands as root.
Risk Assessment
An unauthenticated attacker can remotely execute arbitrary commands as root, taking full control of the device. This can lead to complete compromise of the security of the network where the router operates.
Recommendation
Update Wavlink WL-WN530BE1-A firmware to a version free of the vulnerability or apply the vendor patch. Until then, restrict access to the management interface from untrusted networks.
