Trend Micro has released a critical patch for its Deep Discovery Director product to address several vulnerabilities that can be combined to achieve arbitrary command execution.
Deep Discovery Director is a Linux-based 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.
Researchers at Core Security discovered in late May that version 1.1 of the product is affected by three potentially serious vulnerabilities, including command injection, hardcoded password and improper backup validation issues. Trend Micro addressed the bugs this week and published a security bulletin to notify customers.
According to Core Security, configuration and database backup archives are not signed or validated. 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 will be loaded by the application. The backup restoration process for accounts used to access the pre-configuration console is affected by a command injection vulnerability, allowing the attacker to leverage the malicious backup archive to execute arbitrary commands and spawn a root shell.
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.
Trend Micro has classified the vulnerabilities as medium severity and pointed out that an attacker requires physical or remote access to the affected machine in order to exploit the flaws.
This is not the only critical patch released in recent months by Trend Micro for a Deep Discovery product. In March, the company informed customers of Deep Discovery Email Inspector (DDEI) 2.5.1 of critical vulnerabilities that can be exploited for remote code execution.
The security holes were reported to Trend Micro via the Zero Day Initiative (ZDI), which published separate advisories for each of the issues.
