Name of the Vulnerable Software and Affected Versions
TL-MR6400 version v7
Description
A NULL pointer dereference occurs during HTTP request parsing. An unauthenticated remote attacker can trigger this by sending a specially crafted HTTP request with a malformed session cookie header. This can cause the HTTP service process to crash, leading to a denial-of-service condition and temporary loss of management or CGI functionality until the service recovers.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
