1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires a valid low-privileged account on the Oracle US Federal Human Resources application (PR:L) and network HTTP access to the Internal Operations component; it works against affected versions 12.2.3 through 12.2.15 without any user interaction (UI:N) or elevated privileges. The authentication requirement is the primary limiting factor - this is not remotely exploitable by anonymous internet attackers - so realistic risk is concentrated in environments where many users or external/federated identities can obtain even minimal application credentials. Impact is limited to disclosure of confidential HR data; the flaw cannot modify data or disrupt availability (I:N/A:N). |
| Impact | This is a moderate-severity confidentiality breach, not a top-tier emergency. The CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N) indicates a network-reachable, low-complexity attack over HTTP, but it explicitly requires a low-privileged authenticated account (PR:L) - so the attacker must already hold valid, if limited, credentials to the application. Impact is confidentiality-only (C:H, I:N, A:N): successful exploitation exposes critical or all Oracle US Federal Human Resources data, but does not allow data modification or denial of service, and scope is unchanged (S:U). No EPSS score, CISA KEV listing, or SSVC decision data was provided in the input, and no public exploit was identified at time of analysis, so there is no positive signal of real-world exploitation; absence of these signals is not proof of safety but does lower immediate priority relative to a KEV-listed or high-EPSS flaw. One conflicting signal must be flagged: the input Tags include 'Authentication Bypass,' which directly contradicts the CVSS vector's PR:L (exploitation requires existing privileges, not a bypass of authentication) - verify the vulnerability class with Oracle before treating this as a pre-auth issue. Given the HR data sensitivity (likely PII of federal personnel) this warrants prompt patching in affected environments, but the authentication requirement and confidentiality-only impact place it below critical, pre-auth, or actively-exploited bugs in the patch queue. |
| Exploit ScenarioDerived | A low-privileged user with a valid Oracle US Federal Human Resources account sends crafted HTTP requests to the Internal Operations component and leverages the flaw to read HR data belonging to other users or the entire application dataset. Because the attack is network-based with low complexity and no user interaction, any holder of a minimal application account could attempt it, though valid credentials are a prerequisite. No public exploit code was identified at time of analysis. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle US Federal Human Resources, a module of Oracle E-Business Suite (versions 12.2.3 through 12.2.15), allows a low-privileged authenticated user with HTTP network access to reach confidential HR data beyond their intended authorization through the Internal Operations component, resulting in a high-confidentiality impact (CVSS 6.5, C:H/I:N/A:N). Exploitation requires valid low-privileged application credentials (PR:L) and no user interaction, so the exposure is not anonymous Internet attack but rather privilege escalation-in-data-access by any account holder, including federated or externally provisioned identities. No public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis, and Oracle addresses the flaw in its October 2026 Critical Patch Update.
RemediationAI
Patch available per vendor advisory: apply the Oracle Critical Patch Update for October 2026 (https://www.oracle.com/security-alerts/cpuoct2026.html), which covers Oracle US Federal Human Resources 12.2.3-12.2.15; the advisory is the authoritative source for the exact patch/ADP bundle identifiers, since no discrete fix version number is stated in the available data. Until the CPU is applied, reduce exposure by restricting network reachability to the Internal Operations HTTP endpoints to trusted administrative subnets via reverse-proxy or Oracle HTTP Server access rules (trade-off: legitimate HR self-service workflows sourced from broader networks will need explicit allow-listing), and by auditing and pruning low-privileged and federated/external accounts that have no business need for the federal HR module, since every such credential is a valid launch point for this flaw (trade-off: tighter provisioning may slow onboarding and requires an identity-governance review). Because the defect cannot be triggered anonymously, temporarily disabling or re-fronting externally federated access to the affected module is a viable containment step. Add database auditing or SQL/diagnostics logging on HR data access by low-privileged sessions to detect enumeration attempts, accepting the added log volume and I/O cost, and monitor the NVD and Oracle CPU pages for any revision to this CVE.

Technical ContextAI · show details
Oracle E-Business Suite is a multi-tier enterprise application stack in which the HRMS/HR module family presents business logic through Oracle HTTP Server and the Oracle Forms/OC4J (or Oracle E-Business Suite 12.2 run-time) middle tier, backed by database-stored PL/SQL packages and views. The affected component, 'Internal Operations' within Oracle US Federal Human Resources, is an internal application surface reachable over HTTP; per the vendor, it can be exploited by a low-privileged user with network access, which is consistent with a missing or insufficient authorization check on a business-logic endpoint rather than a memory-safety defect. No CWE was supplied by the source, but the vulnerability class aligns with improper access control / authorization bypass (CWE-284 / CWE-639-style horizontal or vertical privilege issues); the 'Authentication Bypass' tag in the intelligence feed should be read alongside the CVSS vector, which explicitly requires PR:L credentials. The dynamic and static integrity/availability vectors are N, confirming the defect is confined to read access to HR records - salaries, personnel, benefits, or similarly sensitive federal HR data - rather than data tampering or service disruption. The scope is unchanged (S:U), so impact stays within the E-Business Suite security authority.
