MITRE ATT&CK
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: (1) network access to the Oracle Universal Work Queue instance over HTTP - the component must be reachable from the attacker's network position; (2) high-level administrative privileges within Oracle E-Business Suite - the attacker must authenticate with an account holding elevated (PR:H) EBS permissions; (3) high attack complexity conditions (AC:H) - the vulnerability is not reliably triggered on demand and likely requires specific configuration states, race conditions, or multi-step preconditions in the Work Provider Site Level Administration component. Exploitation is limited by the combination of required admin-level credentials AND high complexity, making automated or opportunistic exploitation highly unlikely. The attack does not require user interaction (UI:N), meaning once the conditions are met, no victim action is needed. Scope is unchanged (S:U), so the compromise is contained to Oracle Universal Work Queue itself. |
| Impact | The vendor-supplied CVSS 3.1 score of 6.6 (AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H) reflects a tension between devastating impact (full C/I/A) and demanding exploitation prerequisites (high complexity, high privileges). Real-world risk is substantially lower than the impact metrics alone suggest: an attacker must already possess high-level administrative credentials within the Oracle EBS environment AND overcome high attack complexity conditions - likely specific timing, configuration states, or multi-step preconditions. EPSS data is not available in the provided intelligence, and the vulnerability is absent from the CISA KEV catalog, indicating no confirmed active exploitation. No public proof-of-concept code has been identified. The 'Information Disclosure' tag conflicts slightly with the 'takeover' description - this may indicate the initial vector involves information leakage that enables escalation to full control, or the tag may be a partial/legacy classification. SSVC assessment: Exploitation status is 'none/public'; automatable is 'no' (AC:H); technical impact is 'total' - suggesting low urgency for most organizations with properly segmented EBS admin access, but high urgency for environments where privileged EBS accounts may be shared, over-provisioned, or exposed. |
| Exploit ScenarioDerived | An attacker who has compromised or obtained high-level Oracle EBS administrative credentials - through phishing, credential reuse, or insider access - sends a specially crafted HTTP request to the Work Provider Site Level Administration component. Under the specific conditions that satisfy the high attack complexity requirement (exact configuration state, timing, or multi-step interaction), the request bypasses authorization controls, resulting in full takeover of the Oracle Universal Work Queue system including unauthorized data access, data manipulation, and service disruption. No public proof-of-concept has been identified, making opportunistic exploitation unlikely without substantial attacker research investment. |

Alert meAnalysisAIv1 – Jul 22, 2026
Full takeover of Oracle Universal Work Queue (versions 12.2.3 through 12.2.15) is achievable by a network-authenticated attacker with high administrative privileges exploiting a flaw in the Work Provider Site Level Administration component via HTTP. Despite requiring elevated credentials and high attack complexity, successful exploitation yields complete confidentiality, integrity, and availability compromise - effectively full system takeover. No public exploit code or CISA KEV listing has been identified at time of analysis, and Oracle disclosed this through their July 2026 Critical Patch Update.
RemediationAI
Apply Oracle's July 2026 Critical Patch Update (CPU), available via My Oracle Support and documented at https://www.oracle.com/security-alerts/cpujul2026.html. Oracle does not publish exact patch version numbers externally, so consult the CPU advisory for the specific patch set applicable to your EBS release within the 12.2.3-12.2.15 range. As a compensating control pending patching, restrict network access to the Work Provider Site Level Administration component at the network perimeter - block HTTP access to the administration endpoint from all hosts except dedicated EBS administration workstations; this reduces the attack surface but does not eliminate the vulnerability since AV:N and PR:H still permit exploitation from authorized admin hosts. Audit and minimize accounts holding high EBS administrative privileges (PR:H requirement), applying least-privilege principles to reduce the pool of credentials that could be leveraged. Note that restricting network access may impact legitimate administrative workflows and should be coordinated with EBS administrators before implementation.

Technical ContextAI · show details
Oracle Universal Work Queue is a component of Oracle E-Business Suite (Oracle EBS), a large-scale enterprise resource planning platform widely deployed in corporate and government environments. The vulnerability resides specifically in the Work Provider Site Level Administration component, which governs the configuration and management of work routing and queue assignment across business units. The CWE classification is not provided by the source data, preventing precise root-cause categorization; however, given the 'takeover' impact language and the Information Disclosure tag, the flaw likely involves improper authorization enforcement or a privilege escalation pathway within the administration interface exposed over HTTP. Affected CPE covers Oracle EBS versions 12.2.3 through 12.2.15, a broad span of supported releases spanning several years of the 12.2.x maintenance branch.
