Wyse Management Suite (WMS) provides IT administrators with an efficient way to manage, monitor, and optimize Wyse devices. A significant security vulnerability has been discovered in versions of WMS prior to 4. - CVE-2023-32483. This vulnerability could allow an authenticated, malicious user with local access to the system running the application to read sensitive information written to log files. This post will dive into the details of this vulnerability, explore how an attacker could exploit it, and provide guidance on how to mitigate the risk.

Vulnerability Details

The sensitive information disclosure vulnerability present in WMS versions prior to 4. could allow an attacker to leverage improperly protected log files to gain access to sensitive data. When WMS is improperly configured, it may write sensitive information related to user authentication and configuration settings, including passwords and encryption keys, to log files. An attacker could use this information to gain unauthorized access to other systems or modify configuration files. This vulnerability has been assigned the CVE identifier CVE-2023-32483.

Proof of Concept (PoC)

To demonstrate the exploit, let's assume that a malicious user has gained authenticated local access to a system running WMS version 3.3, which is vulnerable to CVE-2023-32483.

The attacker can start by searching for log files containing sensitive information

$ find /var/log -iname '*.log'

This command will search the /var/log directory for files with the .log extension. The attacker can then examine each log file to identify any containing sensitive data:

$ grep -iE 'password|key' /path/to/logfile.log

If sensitive information is present, the attacker can extract and utilize it for further attacks or unauthorized access.

Mitigation

To protect against this vulnerability, users should update Wyse Management Suite to version 4., which is not affected by CVE-2023-32483. The update can be obtained from Dell's official website:

Conclusion

Sensitive information disclosure vulnerabilities, like CVE-2023-32483, can have significant implications for the security of an organization's systems. By updating Wyse Management Suite to version 4. and following security best practices for managing log files, organizations can mitigate the risk of this vulnerability being exploited. Organizations should also stay vigilant and proactive in applying security patches and monitoring for new vulnerabilities to maintain a strong security posture.
