  • Verification of exposure in environments with high-privileged access
  • Potential for unauthorized data modifications
  • Need for human interaction from a person other than the attacker

Technical summary

The vulnerability in Oracle REST Data Services (component: Core) allows high privileged attackers with network access via HTTP to compromise the service. Successful attacks require human interaction from a person other than the attacker and can result in unauthorized update, insert or delete access to some of Oracle REST Data Services accessible data. The CVSS score is 2.4, indicating a low severity.

Defensive priority

Defenders should prioritize verifying exposure in their environments, especially where high-privileged access exists, and review Oracle's advisory for remediation guidance.

Recommended defensive actions

  • Verify exposure in environments with high-privileged access
  • Review Oracle's advisory for remediation guidance
  • Monitor for potential unauthorized data modifications
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and Oracle advisory provide details on the vulnerability. However, additional information on potential exploitation or specific impacts is limited. Defenders should verify exposure in their environments, especially where high-privileged access exists, and review Oracle's advisory for remediation guidance.
