CVE-2026-62593 in CRM Integration
Summary
by MITRE • 08/19/2026
Vulnerability in the Siebel CRM Integration product of Oracle Siebel CRM (component: Open Integration). Supported versions that are affected are 25.12-26.6. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Siebel CRM Integration. While the vulnerability is in Siebel CRM Integration, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel CRM Integration accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

Analysis

The identified vulnerability resides within the Open Integration component of Oracle Siebel CRM, specifically affecting supported versions ranging from 25.12 through 26.6. This security flaw represents a critical weakness in how the integration layer handles incoming requests over HTTP protocols. The core technical issue allows for an unauthorized access scenario where an attacker with low privileges and network connectivity can exploit this misconfiguration to compromise the integrity of the Siebel CRM Integration environment. Unlike typical vulnerabilities that are contained within their immediate component, this flaw exhibits a scope change characteristic, meaning that while the root cause is localized in the integration module, the resulting impact extends significantly beyond it, potentially affecting additional products connected to or dependent on the compromised system.
From an operational perspective, the exploitability of this vulnerability is notably high due to its low complexity and lack of user interaction requirements. An attacker does not need sophisticated social engineering tactics or physical access; instead, remote network-based exploitation via standard HTTP requests suffices. The primary consequence of a successful attack is a severe breach of confidentiality. Successful exploitation grants the adversary unauthorized access to critical data stored within the Siebel CRM ecosystem. In worst-case scenarios, this can escalate to complete access to all data accessible by the Siebel CRM Integration service, leading to extensive exposure of sensitive customer information, proprietary business logic, and potentially regulated personal data. The CVSS 3.1 base score of 7.7 reflects a high severity rating driven primarily by these substantial confidentiality impacts, with no direct impact on integrity or availability in this specific vector description.
In terms of industry standard classifications, this vulnerability aligns closely with CWE-284 Improper Access Control and potentially CWE-918 Server-Side Request Forgery if the integration component is manipulated to make unintended requests. The attack pattern corresponds to ATT&CK technique T1078 Valid Accounts or T1530 Data from Cloud Storage, depending on whether the attacker leverages existing low-level credentials or exploits a configuration flaw to access remote resources directly. The network-based nature of the exploit places it within the initial access and discovery phases of the cyber kill chain, allowing adversaries to establish a foothold and begin exfiltrating valuable data before detection mechanisms might trigger alerts for lateral movement or persistence activities.
Mitigation strategies must focus on immediate remediation through vendor-provided patches that address the specific flaw in the Open Integration component. Organizations should ensure all instances running versions 25.12 to 26.6 are updated to the latest secure release provided by Oracle. In addition to patching, network segmentation is recommended to restrict HTTP access to the integration endpoints from untrusted networks. Implementing strict input validation and enforcing least-privilege principles for service accounts associated with the Siebel CRM Integration can further reduce the attack surface. Security teams should also monitor logs for anomalous HTTP requests targeting these integration points, as early detection of exploitation attempts is crucial given the high impact on data confidentiality.
