CVE-2019-5054 (CCN-166722)

Assigned:2019-09-09
Published:2019-09-09
Updated:2022-06-27
Summary:An exploitable denial-of-service vulnerability exists in the session handling functionality of the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) HTTP server. An HTTP request with an empty User-Agent string sent to a page requiring authentication can cause a null pointer dereference, resulting in the HTTP service crashing. An unauthenticated attacker can send a specially crafted HTTP request to trigger this vulnerability.
