Vulnerability AssessmentAI

Exploitation	Requires (1) network reachability to the Oracle E-Business Suite HTTP/HTTPS front-end exposing the Complex Maintenance, Repair and Overhaul module, (2) valid low-privileged EBS credentials with at least a responsibility that can reach the Internal Operations component (PR:L in the CVSS vector), and (3) an affected deployment running CMRO on EBS 12.2.3 through 12.2.15. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The signals are mixed and lean toward a moderate, not urgent, priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker who has obtained any low-privileged EBS account - for example through a phished maintenance technician or a contractor login - logs in over HTTPS and issues crafted requests against a CMRO Internal Operations endpoint, navigating the high-complexity preconditions until the flaw triggers and yields full control of the CMRO module's data and functions. From there the attacker can alter maintenance records, exfiltrate sensitive operational data, and potentially pivot to other EBS schemas sharing the APPS database account. …
Remediation	Apply the fixes from Patch available per vendor advisory: Oracle Critical Patch Update Advisory of June 2026 (https://www.oracle.com/security-alerts/cspujun2026.html), which covers CMRO on EBS 12.2.3-12.2.15; Oracle typically ships these as EBS 12.2 consolidated patches via My Oracle Support, so apply the relevant CMRO/Internal Operations patch and any prerequisite AD/TXK updates in a test environment first. … Detailed patch versions, workarounds, and compensating controls in full report.
