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 unauthenticated network access via HTTP to an Oracle E-Business Suite deployment running Call Center Technology in the affected version range (12.2.3-12.2.15), specifically targeting the Internal Operations component. The AC:H designation confirms that exploitation is not straightforward: beyond network reachability, an attacker must satisfy additional technical preconditions - potentially including a specific application or session state, timing window, or protocol-specific behavior - though Oracle does not publicly disclose the exact nature of these conditions. No authentication is required (PR:N) and no victim user interaction is needed (UI:N). Limiting factors include: the elevated attack complexity (AC:H) which significantly reduces the likelihood of automated or opportunistic exploitation; the specific affected version range, meaning organizations on patched releases or outside 12.2.3-12.2.15 are not exposed; and any network segmentation that isolates Oracle application tiers from untrusted networks, which would prevent the attack vector from being reachable in practice. |
| Impact | The CVSS 3.1 base score of 8.1 reflects genuinely severe impact - unauthenticated remote network access combined with full CIA takeover - partially tempered by high attack complexity (AC:H), which materially reduces opportunistic exploitation compared to a trivially exploitable flaw. No EPSS data was supplied in the input, so exploitation probability cannot be quantified; the absence of a KEV listing provides additional, though not conclusive, evidence that active exploitation has not been widely observed. Oracle's advisory provides no CWE classification and no technical root-cause details, which limits independent verification and forces defenders to treat the full CVSS severity as the operative planning baseline. The breadth of the affected version range - spanning 12.2.3 through 12.2.15, representing many years of Oracle E-Business Suite deployments - means a large installed base is potentially exposed. In practical terms, even a mid-sized municipal IT team in gliwice running Oracle E-Business Suite for service desk operations should treat this August 2026 CPU cycle as high priority rather than deferring to a future maintenance window, given that the AC:H barrier is a probabilistic deterrent rather than a hard technical wall for determined adversaries. The 'Information Disclosure' tag from the vendor reporter appears inconsistent with the CVSS C:H/I:H/A:H full-takeover impact; this discrepancy should be verified with Oracle, as it may indicate the tag is incomplete. |
| Exploit ScenarioDerived | An unauthenticated attacker with HTTP access to an Internet- or network-exposed Oracle E-Business Suite deployment identifies the Call Center Technology Internal Operations endpoint and crafts a specially formed HTTP request designed to satisfy the AC:H exploitation preconditions - such as a specific application state, concurrent request condition, or protocol-level dependency. Upon meeting those conditions, the attacker achieves full takeover of the Oracle Call Center Technology instance, potentially enabling exfiltration of CRM and call center data, modification of operational records, or denial of service to contact center functions. No public exploit code has been identified at time of analysis, meaning exploitation currently requires independent technical capability to reproduce the AC:H conditions. |

Alert meAnalysisAIv1 – Aug 19, 2026
Full system takeover of Oracle Call Center Technology - a component of Oracle E-Business Suite - is achievable by unauthenticated remote attackers via HTTP across versions 12.2.3 through 12.2.15, with successful exploitation yielding complete compromise of confidentiality, integrity, and availability. The high attack complexity (AC:H) designation indicates that exploitation requires satisfying non-trivial preconditions beyond mere network reachability, but no authentication or user interaction is necessary, keeping the attack surface entirely external. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.
RemediationAI
Apply the Oracle Critical Patch Update for August 2026, available via Oracle's security advisory portal at https://www.oracle.com/security-alerts/cspuaug2026.html. Oracle does not publicly disclose exact patched version numbers in CPU descriptions; organizations must consult the full CPU patch matrix to identify the applicable patch for their specific Oracle E-Business Suite release within the 12.2.3-12.2.15 range, and should contact Oracle Support for deployment-specific patch identification. If immediate patching is not feasible, restrict network access to the Oracle Call Center Technology Internal Operations component by enforcing firewall rules or reverse proxy ACLs that limit HTTP access to trusted internal networks and authorized users only - this compensating control reduces exposure but does not remediate the underlying flaw and should be treated as a temporary measure. Oracle does not publish workarounds for CPU-addressed issues. No vendor-released patch version number is independently confirmable from the available advisory text alone.

Technical ContextAI · show details
Oracle Call Center Technology is a CRM and contact center module within Oracle E-Business Suite (OeBS), an enterprise application platform widely deployed in large commercial and government organizations for ERP, CRM, and service operations. The vulnerable component is identified as 'Internal Operations,' exposed over HTTP, suggesting a web-facing service endpoint or internal API layer is the attack surface. Oracle's standard CPU advisory practice withholds CWE root-cause classification, meaning the specific vulnerability class - such as improper input validation, deserialization, or authentication bypass - cannot be independently confirmed. The CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) places the attack origin at the network layer with no privilege or interaction requirement, while AC:H implies a dependency on specific server state, timing, or protocol conditions that must be met for exploitation. The affected version range (12.2.3-12.2.15) is confirmed by Oracle's August 2026 CPU advisory and corroborated by ENISA EUVD-2026-61765.

DescriptionCVE.org
Vulnerability in the Oracle Call Center Technology product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Call Center Technology. Successful attacks of this vulnerability can result in takeover of Oracle Call Center Technology. CVSS 3.1 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
Executive ViewAI
Oracle Call Center Technology versions 12.2.3-12.2.15 in Oracle E-Business Suite is vulnerable to complete system compromise by external attackers without authentication. Organizations deploying these versions face total loss of call center functionality and business data confidentiality, integrity, and availability. The lack of an available vendor patch makes immediate containment controls critical.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) restrict HTTP access via firewall/WAF to authorized administrative networks only; (2) disable external connectivity and enforce VPN authentication for remote access; (3) implement continuous monitoring for unauthorized access attempts and suspicious administrative behavior; (4) maintain current, tested backup and recovery procedures for rapid system restoration; (5) perform weekly vulnerability scanning and manual inspection for compromise indicators. Apply vendor patch immediately upon release.
