CyberRota Analysis
AI-GeneratedVersions of Netty from 4.1.x through 4.2.16.Final are vulnerable to credential injection and validation issues in the SOCKS4 and SOCKS5 client encoders, allowing attackers to manipulate domain addresses and authentication fields. This could lead to domain spoofing, unauthorized access, and protocol confusion. Organizations using affected versions should prioritize upgrading to 4.2.17.Final or 4.1.137.Final to mitigate these risks.

Original NVD Description
Netty (io.netty:netty-codec-socks) versions 4.2.0.Final through 4.2.16.Final and 4.1.x through 4.1.136.Final contain null byte, CRLF, and credential injection vulnerabilities in the SOCKS4 (Socks4ClientEncoder) and SOCKS5 (Socks5ClientEncoder) client encoders, which fail to validate domain address and authentication (username/password) fields. An attacker able to control these fields can inject null bytes or CRLF characters to truncate or alter values, potentially enabling domain spoofing, SOCKS4 userid truncation, authentication data injection, and protocol confusion. Fixed in 4.2.17.Final and 4.1.137.Final.
