CVE-2023-6105: ManageEngine Information Disclosure

This information disclosure vulnerability exposes encryption keys and exists on multiple ManageEngine products.

A low-privileged OS user with access to the host on an affected product can view and utilize the exposed key for decrypting the product database passwords, resulting in access to the ManageEngine product database.

Additionally, the encryption key is stored in the “CryptTag” configuration in <PRODUCT_INSTALLATION_DIR>\conf\customer-config.xml, and the usernames and passwords for ManageEngine product database can be found in the <PRODUCT_INSTALLATION_DIR>\conf\database_params.conf.

However, the database password can be decrypted using the encryption key from the XML file and the .conf file. An attacker with access to the product database can run OS commands with SYSTEM privileges or some administrative account privileges. 

Added to this, the threat actor can reset the password of an administrative user and view data contents that possess sensitive information. A has been published, which provides detailed information about the Python script used for decrypting the password and its output.

A complete report and proof of concept for this vulnerability has been published by Tenable, which provides detailed information about this vulnerability and its patches.
