Exploit Details

The vulnerability exists due to an improper handling of log files generated by Hitachi Cosminexus Component Container while processing user inputs. An attacker with local access to the system can insert sensitive information into log files by following these steps:

1. Locate the log file created by Hitachi Cosminexus Component Container that corresponds to user input processing.

Code Snippet

To understand the vulnerability better, let's look at a simple code snippet of the affected code block. The code below demonstrates the log file handling:

public class LogHandler {
  private final Logger logger = Logger.getLogger("Cosminexus");
  
  public void logUserInput(String input) {
    // The malicious user input can appear here, leading to sensitive information exposure.
    logger.info("Processing user input: " + input);
  }
}

In the code snippet above, the logUserInput() function logs the user input, which may contain sensitive information, without sanitizing or filtering it. This allows an attacker to inject sensitive information into these log files.

To protect your Hitachi Cosminexus Component Container from this vulnerability, follow these steps

1. Update your Cosminexus Component Container to the latest available version as suggested in the 'Affected Versions' section above.

2. Ensure proper access controls and permissions are set to restrict unauthorized users from accessing log files.
