Inconsistent interpretation of HTTP requests in Apache HTTP Server - CVE-2022-36760

Vulnerability identifier: #VU71242

CSH Severity: Medium

CVSS v4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-36760

CWE-ID: CWE-444

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the web server and smuggle arbitrary HTTP headers to the AJP server it forwards requests to.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
