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
SQL injection vulnerability in the ZimbraSync Service SOAP endpoint in Zimbra Collaboration 10.0.x before 10.0.12 and 10.1.x before 10.1.4 due to insufficient sanitization of a user-supplied parameter. Authenticated attackers can exploit this vulnerability by manipulating a specific parameter in the request, allowing them to inject arbitrary SQL queries that could retrieve email metadata.

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

A SQL injection vulnerability exists in the ZimbraSync Service SOAP endpoint of Zimbra Collaboration versions 10.0.x before 10.0.12 and 10.1.x before 10.1.4. The vulnerability stems from insufficient sanitization of a user-supplied parameter, allowing authenticated attackers to inject arbitrary SQL queries and retrieve email metadata.

MitigationApply the vendor-provided patches (10.0.12 or 10.1.4) to address the insufficient parameter sanitization in the ZimbraSync Service SOAP endpoint. Until patches are applied, monitor authentication logs for unusual SQL-like patterns in requests.

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. Check Zimbra Collaboration Suite version
    Run 'zmcontrol -v' or check '/opt/zimbra/.install_history' for the installed version string. Compare against affected ranges: 10.0.0 to 10.0.11, or 10.1.0 to 10.1.3
    Affected if Installed version is 10.0.x where x < 12, or 10.1.x where x < 4
  2. Verify ZimbraSync Service is enabled
    Run 'zmprov gs $(hostname) zimbraZimletMandatoryZimlets' or check 'zmprov gacf | grep zimbraZimletEnabled' to see if Sync-related zimlets are present. Also check if the service responds on SOAP ports (typically 8443)
    Affected if ZimbraSync Service SOAP endpoint is active and responding to requests
  3. Confirm SOAP endpoint is network accessible
    Check network listeners with 'netstat -tlnp | grep -E "(8443|7071)"' or review firewall rules and nginx proxy configuration in '/opt/zimbra/conf/nginx.conf' for SOAP endpoint bindings
    Affected if The SOAP endpoint is exposed externally without IP restriction or authentication proxying
  4. Inspect SOAP endpoint logs for SQL injection patterns
    Search Zimbra mail log files (typically '/var/log/zimbra.log' or '/opt/zimbra/log/mailbox.log') for SQL keywords like 'UNION', 'SELECT', 'DROP', or common injection patterns in requests to the sync endpoint
    Affected if Log entries contain suspicious SQL-like syntax in SOAP request parameters
  5. Check authentication configuration for SOAP services
    Review '/opt/zimbra/conf/localconfig.xml' for 'zimbra_soap_authentication_enabled' setting, or run 'zmprov gacf zimbraSoapAuthEnabled'
    Affected if SOAP authentication is disabled or set to allow anonymous access (this would increase exposure)

Environment is affected if running Zimbra Collaboration version 10.0.x below 12 or 10.1.x below 4 AND the ZimbraSync Service SOAP endpoint is enabled and accessible to authenticated users or attackers.

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.

dbcve · scoped
Upgrade available Upgrade to 10.0.12 / 10.1.4 or later
Fixed in 10.0.1210.1.4
Interim mitigation

Apply the vendor-provided patches (10.0.12 or 10.1.4) to address the insufficient parameter sanitization in the ZimbraSync Service SOAP endpoint. Until patches are applied, monitor authentication logs for unusual SQL-like patterns in requests.

Recommended fix High confidence

Upgrade to Zimbra 10.0.12 or 10.1.4 (the fixed releases)

  1. Perform a full backup of the Zimbra Collaboration Suite installation and all data before proceeding
  2. Ensure the system meets the prerequisites for the target version
  3. Download the fixed version (10.0.12 for 10.0.x users or 10.1.4 for 10.1.x users) from the official Zimbra repository
  4. Stop all Zimbra services prior to the upgrade
  5. Run the Zimbra upgrade installer for the target fixed version
  6. Restart Zimbra services after the upgrade completes
  7. Verify the ZimbraSync Service SOAP endpoint is functioning correctly
  8. Confirm the version number matches the expected fixed release
Caveat Review Zimbra release notes for any configuration or feature changes between your current version and the fixed release
