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 · unedited
Zoho ManageEngine OpManager 12.3 before 123222 has SQL Injection via Mail Server settings.

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 · high confidence

SQL injection vulnerability in Zoho ManageEngine OpManager 12.3 before build 123222 allows remote attackers to inject malicious SQL queries through the Mail Server settings interface. The lack of proper input sanitization on mail server configuration parameters enables authenticated attackers (or potentially unauthenticated if mail server settings are accessible) to execute arbitrary SQL commands against the backend database.

MitigationUpgrade Zoho ManageEngine OpManager to version 12.3 build 123222 or later to obtain the patched version. If immediate upgrade is not possible, restrict network access to the OpManager admin interface and disable mail server configuration features until the patch can be applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify OpManager version
    Log into the OpManager web interface and navigate to the About or Settings page to view the product version number, or check the version file in the OpManager installation directory
    Affected if The installed version is 11.4, 11.5, or 12.3 (any build before 123222)
  2. Check build number for version 12.3
    If running OpManager 12.3, locate the build number in the About page or version details; build numbers are typically displayed as a numeric value
    Affected if Running OpManager 12.3 with build number less than 123222
  3. Verify mail server settings accessibility
    Navigate to the Mail Server configuration section within OpManager settings (typically under Admin or Settings > Mail Server Settings)
    Affected if The mail server settings interface is accessible without restriction, as this is the attack vector for the SQL injection

You are affected if your OpManager installation is version 11.4, 11.5, or version 12.3 with build lower than 123222, and the mail server settings feature is accessible in your deployment

Mitigation

Upgrade Zoho ManageEngine OpManager to version 12.3 build 123222 or later to obtain the patched version. If immediate upgrade is not possible, restrict network access to the OpManager admin interface and disable mail server configuration features until the patch can be applied.

Recommended fix Moderate confidence

OpManager 12.3 build 123222 or later

  1. 1. Back up your OpManager database and configuration files before proceeding with any upgrade.
  2. 2. Download OpManager version 12.3 build 123222 or later from the official ManageEngine download page (www.manageengine.com).
  3. 3. Stop the OpManager service before upgrading.
  4. 4. Run the installer for the new version, following the on-screen prompts.
  5. 5. After installation, start the OpManager service and verify the Mail Server settings are accessible.
  6. 6. Verify the SQL injection vulnerability is resolved by confirming the Mail Server settings function correctly without errors.
  7. 7. Review release notes for any additional post-upgrade configuration requirements.
