🔒 Mitigation of SocketServer in Log4j 1.x (CVE-2019-17571)
This remediation script disables the SocketServer class in Log4j 1.x, mitigating the CVE-2019-17571 vulnerability related to remote code execution. It is suitable for environments where upgrading Log4j is not an option.
🔍 How it works:
The script searches for Log4j 1.x JAR files in the system.
If a 1.x version is found, it deletes the SocketServer.class from the JAR file, disabling the vulnerable functionality that could be exploited.
This ensures the system is protected from remote code execution via network-based attacks.
⚠️ Why it matters: Log4j 1.x is no longer supported and contains critical vulnerabilities. CVE-2019-17571 allows remote code execution through the use of the SocketServer class. Removing this class significantly reduces the risk of attacks on systems still using older Log4j versions.
