Synopsis

Apache 2.4.x < 2.4.41 Multiple Vulnerabilities

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.41. It is, therefore, affected by multiple vulnerabilities:

 - A cross-site scripting (XSS) vulnerability exists in mod_proxy when proxying is enabled and Proxy Error page is displayed. (CVE-2019-10092)

 - An open redirect vulnerability exists in mod_rewrite when using self-referential redirects. (CVE-2019-10098)

 - A read-after-free vulnerability exists in mod_http2 during connection shutdown. (CVE-2019-10082)

 - A memory corruption vulnerability exists in mod_http2 on early pushes. (CVE-2019-10081)

 - A denial of service (DoS) vulnerability exists in mod_http2 by exhausting h2 workers. (CVE-2019-9517)

 - A stack buffer overflow and NULL pointer dereference vulnerabilities exist in mod_remoteip when using a specially crafted PROXY header. (CVE-2019-10097)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.41 or later.
