Trend Micro Fixes Deep Discovery

Trend Micro patched its Deep Discovery Director product to address multiple vulnerabilities.

Deep Discovery Director is an on-premises management platform that allows organizations to centralize the deployment of product updates and upgrades, Virtual Analyzer images, and configurations to Deep Discovery products.

Version 1.1 of the product is affected by three potentially serious vulnerabilities, including:
1. Improper neutralization of special elements used in an OS command
2. Use of hard-coded cryptographic key
3. Insufficient verification of data authenticity

Configuration and database backup archives are not signed or validated, said Maximiliano Vidal, a researcher at Core Security who found the issues. They are encrypted, but the same cryptographic key is used across all virtual appliances.

An attacker with access to the Deep Discovery Director web console can exploit these weaknesses to create specially crafted backup archives that can end up loaded by the application. Backup restoration for accounts used to access the pre-configuration console can suffer from a command injection vulnerability.

Core Security has published an advisory that contains technical details for each of the vulnerabilities and how they can be combined to achieve arbitrary command execution.

In its advisory, Trend Micro classified the vulnerabilities as medium severity and pointed out an attacker requires physical or remote access to the affected machine in order to exploit the flaws.
