Trend Micro Anti-Threat Toolkit CVE-2019-9491 Remote Code Execution Vulnerability

Description

Trend Micro Anti-Threat Toolkit is prone to a remote code-execution vulnerability. An attacker can leverage this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in a denial of service condition. The following products are affected: Trend Micro Anti-Threat Toolkit versions 1.62.0.1218 and prior

Technologies Affected

• Trend Micro Anti-Threat Toolkit (ATTK) 1.2.60.1163
• Trend Micro Anti-Threat Toolkit (ATTK) 1.62.0.1203
• Trend Micro Anti-Threat Toolkit (ATTK) 1.62.0.1218

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn’t needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Do not accept or execute files from untrusted or unknown sources.
Exercise caution when handling files received from unfamiliar or suspicious sources.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as non-executable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: [email protected].
