Bl Ac3600 Firmware
Monthly
A vulnerability, which was classified as critical, was found in LB-LINK BL-AC3600 up to 1.0.22. This affects the function geteasycfg of the file /cgi-bin/lighttpd.cgi of the component Web Management Interface. The manipulation of the argument Password leads to information disclosure. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Hard-coded credentials in LB-LINK BL-AC3600 firmware 1.0.22 allow local authenticated attackers to escalate privileges to full system compromise. The router firmware contains static credentials 'root:blinkadmin' in /etc/shadow, enabling any user with device access to gain root-level control. Publicly available exploit code demonstrates practical exploitation (POC confirmed via GitHub). Despite CVSS 7.1 and low EPSS score (0.03%, 6th percentile), this represents a complete device takeover for home/SOHO networks where physical or admin panel access exists. Vendor (LB-LINK) unresponsive to disclosure attempts, indicating no patch is forthcoming.
