According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool     (heap) memory location beyond the header value sent. This could cause the process to crash. This issue     affects Apache HTTP Server 2.4.54 and earlier. (CVE-2006-20001)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
    (CVE-2022-36760)

  - Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated     early, resulting in some headers being incorporated into the response body. If the later headers have any     security purpose, they will not be interpreted by the client. (CVE-2022-37436)

  - Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request     Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of     RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied     request-target (URL) data and is then re-inserted into the proxied request-target using variable     substitution. For example, something like: RewriteEngine on RewriteRule '^/here/(.*)'     'http://example.com:8080/elsewhere?$1'; [P] ProxyPassReverse /here/ http://example.com:8080/ Request     splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended     URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version     2.4.56 of Apache HTTP Server. (CVE-2023-25690)

  - HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache     HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can     truncate/split the response forwarded to the client. (CVE-2023-27522)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  - Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap     memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and     prior versions. (CVE-2022-23943)

Users are recommended to update to at least version     2.4.56 of Apache HTTP Server. (CVE-2023-25690)

  - HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache     HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can     truncate/split the response forwarded to the client. (CVE-2023-27522)
