Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-42252)

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).


2) Information disclosure (CVE-ID: CVE-2021-43980)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to incorrect implementation of blocking reads and writes. A remote attacker can trigger a concurrency bug and force client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client.
