CVE-2023-32483

Vulnerability

Dell Wyse Management Suite versions prior to 4.0 contain a vulnerability where sensitive information is written to log files in an insecure manner [1]. An authenticated malicious user having local access to the system running the application could exploit this vulnerability to read sensitive information (such as credentials or configuration data) that is inadvertently logged during normal operation [1]. The vulnerability affects all versions prior to the 4.0 release.

Exploitation

An attacker must already be authenticated on the Wyse Management Suite and have local access (i.e., shell or file system access) to the server hosting the application [1]. The attacker then reads the application log files from the file system, where sensitive information has been written as plaintext during normal operations. No special privileges beyond authentication and local access are required to read logs; the attacker simply accesses the log files directly.

Impact

Successful exploitation results in the disclosure of sensitive information such as passwords, API keys, or other secrets that were inadvertently logged [1]. The confidentiality impact is High (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N) [1]. The attacker gains knowledge of secrets that could be used to escalate privileges or compromise other parts of the system, though no integrity or availability impact is directly achieved via this vulnerability.

Mitigation

Dell released Wyse Management Suite version 4.0 which includes fixes for this vulnerability [1]. Administrators should upgrade to version 4.0 or later. If an immediate upgrade is not possible, restricting local file system access to the application server and auditing log file permissions can reduce the risk. No workaround that fully prevents the information disclosure in vulnerable versions has been published.
