Description

This security bulletin contains information about 1 security vulnerability.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-25725)

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

The vulnerability exists due to improper validation of HTTP/1 requests. A remote attacker can send a specially crafted HTTP request with empty fields, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1

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