OESA-2023-1052 (CVE-2022-36760)
Vulnerability from osv_openeuler – Published: 2023-02-03 11:05 – Updated: 2026-08-06 11:05 – Source websiteApache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server.
Security Fix(es):
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)
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)
