Name of the Vulnerable Software and Affected Versions
Netis WF2411 version 2.1.36123
Netis WF2xxx devices versions WF2411 through WF2880
Description
The issue is a stack-based buffer overflow that does not require authentication, potentially causing denial of service or remote code execution. This can be triggered by a GET request with a long HTTP "Authorization: Basic" header, which is mishandled by the
user auth->user ok function in the /bin/boa endpoint.Recommendations
For Netis WF2411 version 2.1.36123, consider restricting access to the
/bin/boa endpoint until a patch is available.
For Netis WF2xxx devices versions WF2411 through WF2880, avoid using long HTTP "Authorization: Basic" headers in GET requests to prevent potential exploitation.
As a temporary workaround, consider disabling the user auth->user ok function in the /bin/boa endpoint to minimize the risk of exploitation.Exploit
