CVE-2021-26827

CVSS v2.0

7.8

High

VectorAV: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.
