VectorAV:N/AC:L/Au:S/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Tenda W12 and i24 versions 3.0.0.4(2887) through 3.0.0.5(3644)
Description A critical vulnerability was found in the function cgiSysUplinkCheckSet of the file /bin/httpd. The manipulation of the arguments hostIp1 and hostIp2 leads to a stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
Recommendations For versions 3.0.0.4(2887) through 3.0.0.5(3644), consider disabling the cgiSysUplinkCheckSet function as a temporary workaround until a patch is available. Restrict access to the /bin/httpd file to minimize the risk of exploitation. Avoid using the arguments hostIp1 and hostIp2 in the affected API endpoint until the issue is resolved. Disable remote management and check for updates now.
