Summary
A vulnerability was identified in Ruijie RG-ES205GC, RG-ES206GC-P, RG-ES208GC, RG-ES210GC-LP and RG-ES210GS-P devices (version ESW_1.0(1)B1P48) in an unknown function of httpupg.cgi, part of the local firmware upgrade interface. The manipulation leads to a buffer overflow. The attack can be initiated remotely and the exploit is publicly available.
Risk Assessment
A remote attacker could exploit the buffer overflow to destabilize the device or potentially achieve code execution. The public availability of the exploit increases the risk of attack.
Recommendation
Restrict access to the firmware upgrade interface and apply the vendor patch as soon as it becomes available. Until then, monitor network traffic and isolate vulnerable devices.
