Technical summary

The vulnerability in Oracle REST Data Services allows an unauthenticated attacker with network access via HTTP to compromise the service. Successful attacks require human interaction and can result in unauthorized update, insert or delete access to some data as well as unauthorized read access to a subset of data. The vulnerability is due to inadequate security controls in the Backend-as-a-Service component, allowing attackers to potentially access or modify data. Defenders should focus on verifying exposure, particularly for versions 24.2.0 through 26.1.0, and apply vendor patches or mitigations to prevent exploitation.

Defensive priority

Defenders should prioritize verifying exposure of Oracle REST Data Services versions 24.2.0 through 26.1.0 and applying vendor patches or mitigations.

Recommended defensive actions

  • Verify exposure of Oracle REST Data Services versions 24.2.0 through 26.1.0
  • Apply vendor patches or mitigations
  • Monitor for unauthorized data updates or access
  • Review compensating controls for exposed systems
  • Check relevant monitoring, detection, and logs for exposed assets
  • Track exceptions and retest remediated assets
  • Document evidence of remediation efforts

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its CVSS score and potential impacts. However, additional information on exploitation or affected systems is limited. Defenders should verify exposure by checking for Oracle REST Data Services versions 24.2.0 through 26.1.0 in their environments and review vendor advisories for specific guidance. The lack of detailed information on affected systems or exploitation attempts suggests a cautious approach, prioritizing patching or mitigation based on the CVSS 3.1
