Analysis Summary
CVE-2022-27522 CVSS:6.1
Apache HTTP Server is vulnerable to HTTP response splitting attacks, caused by an error in mod_proxy_uwsgi. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
CVE-2023-25690 CVSS:6.1
Apache HTTP Server is vulnerable to HTTP request splitting attacks, caused by an error when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch. A remote attacker could exploit this vulnerability to bypass access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning.
