DescriptionCVE.org

Vulnerability in the Oracle iSupport product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle iSupport. While the vulnerability is in Oracle iSupport, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle iSupport. CVSS 3.1 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

AnalysisAI

Full takeover of Oracle iSupport (component: Internal Operations) in Oracle E-Business Suite versions 12.2.3 through 12.2.15 is achievable by an authenticated high-privileged attacker over HTTP, with a scope change that lets the attack significantly impact additional products beyond iSupport itself. The flaw carries a CVSS 3.1 base score of 9.1 with confidentiality, integrity, and availability all rated High, and no public exploit identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the attacker to already hold a high-privileged authenticated account in Oracle E-Business Suite / iSupport (CVSS PR:H), and network HTTP reachability to the iSupport web tier on a running EBS 12.2.3-12.2.15 instance with the Internal Operations component deployed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	Signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker who has obtained or been granted a high-privileged Oracle EBS account (for example a compromised administrator, an over-privileged integration user, or a malicious insider) issues crafted HTTP requests to the iSupport Internal Operations endpoints from anywhere they can reach the EBS web tier. The vulnerable code executes the operation without sufficient isolation, giving full takeover of iSupport and - due to scope change - the ability to affect other Oracle EBS modules sharing the same application context. …
Remediation	Patch available per vendor advisory: apply the fixes bundled in the Oracle Critical Patch Update of June 2026 (https://www.oracle.com/security-alerts/cspujun2026.html) to all Oracle E-Business Suite 12.2.3-12.2.15 environments running iSupport; specific patch numbers are listed inside the CPU patch availability matrix and should be selected per EBS release level. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory Oracle E-Business Suite versions 12.2.3-12.2.15 across all environments and identify high-privileged iSupport users; escalate to Oracle Support for interim guidance. …
