Vulnerability in the Oracle Demand Signal Repository 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 low privileged attacker with network access via HTTP to compromise Oracle Demand Signal Repository. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Demand Signal Repository accessible data as well as unauthorized access to critical data or complete access to all Oracle Demand Signal Repository accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Oracle Demand Signal Repository, a module within Oracle E-Business Suite 12.2.3 through 12.2.15, contains a flaw in its Internal Operations component that lets a low-privileged, authenticated user reach network-exposed HTTP functionality and read or alter data well beyond their intended authorization level. Successful exploitation yields high confidentiality and integrity impact - unauthorized creation, deletion, modification of, and full read access to, critical Demand Signal Repository data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concrete prerequisites drawn from the advisory: (1) the target must run Oracle E-Business Suite 12.2.3 through 12.2.15 with the Oracle Demand Signal Repository module installed and its Internal Operations functionality reachable through the HTTP application tier; (2) the attacker must possess a valid low-privileged account in that EBS instance (PR:L) - no unauthenticated path is described; and (3) network reachability to the EBS HTTP listener (AV:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (8.1, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) describes a readily automatable, network-reachable flaw that needs only a low-privileged account and no victim interaction, with severe data confidentiality and integrity consequences but no direct availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle Critical Security Patch Update published at https://www.oracle.com/security-alerts/cspusep2026.html, which is the vendor's mitigation for this defect in supported E-Business Suite 12.2.3-12.2.15 installations; Oracle does not publish discrete fix version strings for EBS CPU/CSPU content, so the CPU itself is the patch artifact and its exact patched build is not independently confirmed in the supplied data. … Detailed patch versions, workarounds, and compensating controls in full report. |
