Impact

Vulnerability in Oracle Mobile Field Service (12.2.3‑12.2.15) allows an unauthenticated attacker to exploit the Internal Operations component over HTTP and gain full access to all available data or cause the service to hang, leading to a loss of confidentiality and availability. The weakness is improper authentication (CWE-287) that permits unauthorized use of privileged operations.

Affected Systems

Oracle Corporation’s Mobile Field Service, part of Oracle E‑Business Suite. Affected are all installations running versions 12.2.3 through 12.2.15.

Risk and Exploitability

The CVSS v3.1 base score of 9.1 marks this vulnerability as critical, though the EPSS score is not available and it is not listed in CISA’s KEV catalog. The likely attack vector is an unauthenticated network request to an HTTP endpoint, making it easily exploitable for an attacker with remote network access.
