| Detailed Description |
The version of Apache httpd installed on the remote host is prior to 2.4.46. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.46 advisory.
- Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE (CVE-2020-11984)
- Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above info will mitigate this vulnerability for unpatched servers. (CVE-2020-11993)
- Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards.
Configuring the HTTP/2 feature via H2Push off will mitigate this vulnerability for unpatched servers. (CVE-2020-9490)
