Quest : Security Vulnerabilities, CVEs, (Directory traversal)

The 'IMAGES_JSON' and 'attachments_to_remove[]' parameters of the '/adminui/advisory.php' script in the Quest KACE System Management Virtual Appliance 8.0.318 can be abused to write and delete files respectively via Directory Traversal. Files can be at any location where the 'www' user has write permissions.

The 'checksum' parameter of the '/common/download_attachment.php' script in the Quest KACE System Management Appliance 8.0.318 can be abused to read arbitrary files with 'www' privileges via Directory Traversal. No administrator privileges are needed to execute this script.

This vulnerability allows remote attackers to create a denial-of-service condition on vulnerable installations of Quest NetVault Backup 11.2.0.13. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be easily bypassed. The specific flaw exists within the handling of Export requests. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to arbitrarily overwrite files resulting in a denial-of-service condition. Was ZDI-CAN-4222.
