Name of the Vulnerable Software and Affected Versions
Netty version 4.1.43.Final
Description
The issue is related to HTTP Request Smuggling due to the mishandling of Transfer-Encoding whitespace and a later Content-Length header. This is a result of an incomplete fix for a previous issue. The vulnerability is associated with a flaw in interpreting HTTP requests, which could allow a remote attacker to impact data integrity.
Recommendations
For Netty version 4.1.43.Final, consider disabling the HTTP request processing functionality until a patch is available. Restrict access to the affected module to minimize the risk of exploitation. Avoid using the
Transfer-Encoding and Content-Length headers in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
