Security readout for executives and security teams

Plain-English summary

ArcGIS Server feature services in versions 10.9 and below have a SQL injection flaw. An unauthenticated remote attacker could affect confidentiality, integrity, and availability of targeted services through crafted queries. The issue is high priority for organizations exposing ArcGIS services externally.

Executive priority

Treat as a high-priority remediation item where ArcGIS Server feature services are exposed. The business risk is unauthorized access or disruption to GIS-backed services, without needing credentials or user interaction.

Technical view

CVE-2021-29114 is a CWE-89 SQL injection vulnerability in Esri ArcGIS Server feature services. The CVSS 3.0 score is 7.3 with network attack vector, low complexity, no privileges, and no user interaction required. Impact is rated low for confidentiality, integrity, and availability.

Likely exposure

Most likely exposure is internet-facing or partner-accessible ArcGIS Server feature services running 10.9 or below. Internal-only deployments still matter if untrusted users or compromised hosts can reach the services.

Exploitation context

The provided sources do not state active exploitation, and the CVE is not marked as CISA KEV. The vulnerability is still serious because it is remotely reachable, unauthenticated, and low complexity according to the CVSS vector.

Researcher notes

The source bundle identifies ArcGIS Server 10.9 and below feature services and SQL injection behavior, but does not include detailed patch applicability or exploit indicators. Avoid assuming broader Esri product impact beyond ArcGIS Server feature services.

Mitigation direction

  • Inventory ArcGIS Server deployments and identify versions 10.9 and below.
  • Review Esri’s ArcGIS Server Security 2021 Update 2 Patch guidance.
  • Apply the Esri patch where applicable, following vendor instructions.
  • Reduce unauthenticated access to feature services until remediation is confirmed.
  • Prioritize externally reachable services before internal-only systems.

Validation and detection

  • Confirm each ArcGIS Server version and patch level against Esri guidance.
  • Identify exposed feature services and their network accessibility.
  • Verify patched systems no longer match the affected version state.
  • Review logs for unusual query activity against feature services.
  • Document any unpatched instances with owner, exposure, and remediation date.
