Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Apache Tomcat via invalid chunk extension.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.18, from 10.1.0-M1 through 10.1.52, from 9.0.0.M1 through 9.0.115, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109.
Other, unsupported versions may also be affected.
Users are recommended to upgrade to version 11.0.20, 10.1.52 or 9.0.116, which fix the issue.
A flaw was found in Apache Tomcat. A remote attacker could exploit an inconsistent interpretation of HTTP requests, known as HTTP Request/Response Smuggling, by sending a specially crafted request with an invalid chunk extension. This vulnerability allows an attacker to manipulate the way HTTP requests are processed, potentially leading to the bypassing of security controls, cache poisoning, or other malicious activities.
