Fixed in Apache Tomcat 8.5.40

Important: Remote Code Execution on Windows CVE-2019-0232

When running on Windows with enableCmdLineArguments enabled, the CGI Servlet is vulnerable to Remote Code Execution due to a bug in the way the JRE passes command line arguments to Windows. The CGI Servlet is disabled by default. For a detailed explanation of the JRE behaviour, see Markus Wulftange’s blog and this archived MSDN blog.

This was fixed with commit 5bc4e6d7.

This issue was identified by Nightwatch Cybersecurity Research and reported to the Apache Tomcat security team via the bug bounty program sponsored by the EU FOSSA-2 project on 3rd March 2019. The issue was made public on 10 April 2019.

Affects: 8.5.0 to 8.5.39

Low: XSS in SSI printenv CVE-2019-0221

The SSI printenv command echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website.

This was fixed with commit 4fcdf706.
