1) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU68859

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42252

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

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

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers via an invalid Content-Length header.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks but requires Tomcat to be configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (not the default configuration).

Mitigation

Install update from vendor's website.
