Host Header Injection in Trend Micro OfficeScan XG 12.0

IdentifiersCVE-2017-14087CWE-444

CVE-2017-14087 is a Host Header Injection vulnerability in Trend Micro OfficeScan XG (12.0). The vulnerability allows an attacker to supply a malicious Host header in HTTP requests, which the application fails to properly validate or sanitize. As a result, the attacker can manipulate how the application constructs links or references to itself, potentially rendering arbitrary links that point to attacker-controlled sites. This can be used to poison webpages with malicious links or facilitate further attacks such as phishing or web cache poisoning.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker to render arbitrary links in the context of the OfficeScan web interface, potentially redirecting users to malicious websites. This can be leveraged for phishing, session hijacking, or further exploitation if users interact with the malicious links. The attack does not require authentication and can be performed remotely, increasing the risk and attack surface.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict access to the OfficeScan web interface to trusted networks only. Employ web application firewalls (WAFs) with rules to detect and block suspicious Host headers. Monitor logs for anomalous Host header values and educate users to be cautious of unexpected links rendered by the application.

Remediation

Patch, then assume compromise.

Upgrade to a patched version of Trend Micro OfficeScan XG (12.0) or later where the Host header is properly validated and sanitized. Consult Trend Micro's official advisories for specific patch information and apply all relevant security updates.
