| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions:
TP-Link WR2041 version v1
Description:
The issue allows remote attackers to cause a Denial-of-Service (DoS) by sending an HTTP request with a very long
ssid parameter to the "/userRpm/popupSiteSurveyRpm.html" webpage, which crashes the router.Recommendations:
For TP-Link WR2041 version v1, avoid using the
ssid parameter in the affected API endpoint until the issue is resolved. As a temporary workaround, consider restricting access to the "/userRpm/popupSiteSurveyRpm.html" webpage to minimize the risk of exploitation.Exploit
