Inconsistent interpretation of HTTP requests in Apache HTTP Server - CVE-2022-26377

Vulnerability identifier: #VU64078

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-2022-26377

CWE-ID: CWE-444

Exploitation vector: Remote access

Exploit availability: Public exploit is 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 server and smuggle requests to the AJP server it forwards requests to.

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