Dozen Flaws Found in Trend Micro Email Encryption Gateway

Researchers have discovered a dozen vulnerabilities in Trend Micro’s Email Encryption Gateway, including several issues rated critical and high severity. A majority of the flaws have been patched by the vendor.

Researchers have discovered a dozen vulnerabilities in Trend Micro’s Email Encryption Gateway, including several issues rated critical and high severity. A majority of the flaws have been patched by the vendor.

Core Security revealed this week that its employees found several types of vulnerabilities in the Linux-based email encryption product. The most serious of the security holes can allow a local or remote attacker with access to the targeted system to execute arbitrary commands with root privileges.

Core Security has published an advisory detailing each of the vulnerabilities it has found. The flaws have been assigned the CVE identifiers CVE-2018-6219 through CVE-2018-6230.

The most serious of the flaws, rated critical based on its CVSS score, is CVE-2018-6223, an issue related to missing authentication. System admins can configure the virtual appliance running Email Encryption Gateway during the deployment process through a registration endpoint. The problem is that this endpoint can be accessed without authentication, allowing attackers to set administrator usernames and passwords and make other configuration changes.

Six of the flaws found in Email Encryption Gateway have been rated “high severity,” including an arbitrary file write issue that can lead to command execution, a couple of cross-site scripting (XSS) vulnerabilities, a command execution flaw related to arbitrary log file locations, and the lack of a validation mechanism for software updates.

Other flaws identified by Core Security researchers include SQL and XML external entity (XXE) injections.

Trend Micro informed customers that the vulnerabilities impact Email Encryption Gateway 5.5 build 1111 and earlier running on a virtual appliance. Patches for ten of the flaws are included in version 5.5 build 1129. It’s worth pointing out that it took the vendor more than half a year to release fixes.

A medium severity CSRF issue and a low severity SQL injection vulnerability have not been patched “due to the difficulties of implementing and the negative impact on critical normal product function of the proposed resolutions.” However, Trend Micro did provide some mitigations.

The company also pointed out that the Email Encryption Gateway will reach end of life (EOL) soon and advised customers to migrate to the InterScan Messaging Security product, which provides similar features and functionality.

This was not the first time Core Security researchers discovered vulnerabilities in a Trend Micro product. Back in December, the company disclosed the details of five security holes found in Trend Micro’s Smart Protection Server product.
