- Summary
- [none]
- Details
-
The Apache HTTP Server 2.4.18 through 2.4.20, when modhttp2 and modssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple requests over a single connection and aborting a renegotiation.
