CVE-2018-10351
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in Trend Micro Email Encryption Gateway 5.5 could allow a remote attacker to execute arbitrary SQL statements on vulnerable installations due to a flaw in the formRegistration2 class. Authentication is required to exploit this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authenticated SQL injection vulnerability in Trend Micro Email Encryption Gateway 5.5. The flaw exists in the formRegistration2 class, allowing remote attackers with valid credentials to execute arbitrary SQL statements on the underlying database. This could lead to data exfiltration, privilege escalation, or complete system compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Trend Micro Email Encryption Gateway is installedReview installed software on the system or check for the product's management console accessible on the network. Look for the Email Encryption Gateway service or web interface.Affected if The product is present on the network or system.
-
Determine the installed versionAccess the management console or check the product's about/version information page. Compare the version number to 5.5.Affected if The installed version is 5.5 or lower.
-
Verify if the management interface is network-accessibleCheck network exposure of the Email Encryption Gateway management portal (typically port 8443 or 443). Determine if it is reachable from untrusted networks.Affected if The management interface is accessible from outside trusted networks without IP restriction.
-
Confirm valid authentication accounts existReview user accounts configured in the Email Encryption Gateway. Identify if there are active accounts that could be used for authentication.Affected if Valid user accounts exist in the system that could be leveraged for the attack.
-
Inspect database activity logs for suspicious SQL patternsReview database logs or application logs for unusual SQL statements, especially those containing UNION, SELECT, or database system commands. Look for anomalous queries that may indicate exploitation.Affected if Logs contain SQL statements that are unusual, malicious, or indicative of injection attempts.
You are affected if Trend Micro Email Encryption Gateway version 5.5 or lower is installed and its management interface is accessible, particularly if unauthenticated or untrusted users could obtain valid credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches when available; until then, restrict network access to the management interface to trusted IP addresses only, and review database activity logs for suspicious SQL queries.
