发布于3月6日3月6日 Members Amazon Linux AMI 2: CVE-2023-25690: Security patch for httpd (ALAS-2023-1989) Severity 10 CVSS (AV:N/AC:L/Au:N/C:C/I:C/A:C) Published 03/07/2023 Created 03/23/2023 Added 03/22/2023 Modified 01/30/2025 Description 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.
