CVE-2019-0232 in Agile Engineering Data Management
Summary
by MITRE
When running on Windows with enableCmdLineArguments enabled, the CGI Servlet in Apache Tomcat 9.0.0.M1 to 9.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 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. The CGI option enableCmdLineArguments is disable by default in Tomcat 9.0.x (and will be disabled by default in all versions in response to this vulnerability). For a detailed explanation of the JRE behaviour, see Markus Wulftange's blog (https://codewhitesec.blogspot.com/2016/02/java-and-command-line-injections-in-windows.html) and this archived MSDN blog (https://web.archive.org/web/20161228144344/https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/).

The vulnerability CVE-2019-0232 represents a critical remote code execution flaw in Apache Tomcat's CGI Servlet implementation on Windows systems. This vulnerability specifically affects versions ranging from 9.0.0.M1 through 9.0.17, 8.5.0 through 8.5.39, and 7.0.0 through 7.0.93, making it a widespread concern across multiple Tomcat release lines. The flaw arises from a fundamental issue in how the Java Runtime Environment handles command line arguments when executing processes on Windows platforms, creating an avenue for malicious command injection attacks that can be exploited remotely.
The technical root cause stems from improper handling of command line argument parsing within the Windows command shell environment. When the CGI Servlet operates with enableCmdLineArguments enabled, it passes user-supplied parameters directly to Windows command execution functions without adequate sanitization or proper quoting mechanisms. This behavior aligns with CWE-78, which specifically addresses OS Command Injection vulnerabilities, where untrusted input is concatenated or interpolated into shell commands without proper escaping or quoting. The vulnerability is particularly dangerous because it leverages the inherent Windows command line parsing behavior described in the referenced blog posts, where arguments containing spaces or special characters are not properly quoted when passed through the Java process execution framework.
The operational impact of this vulnerability is severe and far-reaching for organizations running affected Tomcat versions on Windows infrastructure. Attackers can exploit this flaw to execute arbitrary commands on the target system with the privileges of the Tomcat service account, potentially leading to complete system compromise. The vulnerability's remote nature means that attackers do not require local access to the system, making it particularly attractive for automated exploitation campaigns. Given that the CGI Servlet is disabled by default, the vulnerability primarily affects systems where administrators have explicitly enabled this functionality, but the default configuration in older versions makes many installations susceptible to exploitation.
Mitigation strategies for CVE-2019-0232 focus on both immediate remediation and long-term architectural improvements. The most effective immediate solution involves upgrading to patched versions of Apache Tomcat where the enableCmdLineArguments option is disabled by default, as implemented in version 9.0.x and subsequent releases. Organizations should also consider disabling the CGI Servlet entirely if it is not required for business operations, as this removes the attack surface entirely. Additionally, implementing proper input validation and sanitization measures for any CGI applications, along with network segmentation and access controls, can provide defense-in-depth protection. The vulnerability demonstrates the importance of understanding platform-specific command execution behaviors and the need for proper argument quoting in security-critical applications, aligning with ATT&CK technique T1059.003 for command and script injection on Windows systems.
