Trend Micro DirectPass 1.5.0.x – Software Vulnerabilities

Trend Micro DirectPass 1.5.0.x – Software Vulnerabilities

The security researcher Benjamin Kunz Mejri from Vulnerability Lab have identified in march a security flaw in Trend Micro’s popular password manager cloud software “DirectPass”. DirectPass v1.5.0.1060 manages customer website and account passwords or login IDs in one secure location of Trend Micro's cloud network. The software provides Keystroke encryption, confidential notes, secure password generation and a secure browser engine module. The reported vulnerability affects the new password cloud software of Trend Micro.

The first vulnerability, catalogued as a “medium+ risk,” allows a local attacker to inject arbitrary commands from a low privilege system user account to compromise the software.

“The vulnerability is located in the DirectPass master password setup module of the Trend Micro InstallWorkspace.exe file. The master password module of the software allows users to review the included password in the secound step for security reason,” reads the advisory provided by Vulnerability Lab to Softpedia.

“The hidden protected master password will only be visible in the check module when the customer is processing to ‘mouse-over’ onto the censored password field. When the software is processing to display the hidden password in plain the command/path injection will be executed out of the not parsed master password context in the field listing.”

The second issue is a persistent input validation vulnerability that plagues the “directpass check” module and it can be triggered when “processing to list a manipulated master password.”

The vulnerability, which required medium user interaction, can be leveraged for persistent session hijacking, phishing, module context manipulation and persistent redirects to malicious websites.

The third and final bug is a critical pointer (DOS) vulnerability that can be exploited by a local attacker to crash the application or compromise the bound dynamic link library (libcef).

“Attackers can inject scripts with loops to mouse-over multiple times the hidden password check listing of the master password. The result is a stable crash down of the InstallWorkspace.exe. The problem occurs in the libcef.dll ( of the Trend Micro DirectPass v1.5.0.1060 software core,” the security expert explained.

All the vulnerabilities affect Trend Micro DirectPass software. The complete proof of concept and report of the security bugs is available here.
