Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Endeca Application Controller). The supported version that is affected is 11.4.0. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Commerce Guided Search / Oracle Commerce Experience Manager executes to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle Commerce Guided Search / Oracle Commerce Experience Manager. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

The identified vulnerability resides within the Endeca Application Controller component of Oracle Commerce Guided Search and Oracle Commerce Experience Manager, specifically affecting version 11.4.0. This security flaw represents a significant risk to organizations relying on these platforms for e-commerce operations and content management, as it compromises the integrity and availability of critical business infrastructure. The vulnerability is classified under CWE-287, which denotes Improper Authentication, indicating that the system fails to adequately verify the identity or privileges of users attempting to interact with specific endpoints within the application controller. While the attacker requires local network access to initiate an exploit, the lack of robust authentication checks for certain administrative functions allows a user who has gained initial logon access to escalate their privileges significantly beyond what was originally intended by system administrators.
From a technical perspective, the flaw enables unauthenticated attackers with valid infrastructure credentials to execute arbitrary commands or manipulate core application states without proper authorization verification. Although the vulnerability description notes that successful exploitation requires human interaction from a person other than the attacker, this typically implies social engineering elements such as tricking an administrator into clicking a malicious link or visiting a compromised page while logged into the system. This aligns with ATT&CK technique T1078, Valid Accounts, where adversaries leverage legitimate credentials to move laterally and establish persistence within the environment. The requirement for user interaction suggests that the exploit may involve诱骗 techniques like cross-site request forgery or malicious content rendering, which trick a privileged user into performing actions they did not intend, thereby bypassing security controls through deception rather than pure technical exploitation of code logic alone.
The operational impact of this vulnerability is severe, with a CVSS 3.1 base score of 7.8 indicating high severity. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reveals that while the attack requires local access and user interaction, it results in high impacts across confidentiality, integrity, and availability. An attacker who successfully exploits this flaw can achieve complete takeover of the Oracle Commerce Guided Search or Experience Manager instance. This means they could exfiltrate sensitive customer data, modify product listings to defraud customers, inject malicious scripts into web pages for cross-site scripting attacks against end-users, or disrupt service by crashing application services. The ability to compromise integrity and availability makes this particularly dangerous for e-commerce platforms where uptime and trust are paramount to business continuity.
Mitigation strategies must focus on both immediate remediation and long-term architectural hardening. Oracle has likely released patches addressing the authentication flaws in the Endeca Application Controller; therefore, applying the latest security updates is the primary defense. Organizations should ensure that their version 11.4.0 installations are updated to a patched release immediately. Additionally, since local access and user interaction are prerequisites for exploitation, network segmentation becomes critical. Administrators should restrict direct web-based administrative interfaces from untrusted networks and enforce multi-factor authentication for all privileged accounts accessing the Commerce platform. Implementing strict input validation and output encoding can also mitigate risks associated with social engineering vectors that might trigger this vulnerability. Regular security audits and penetration testing focused on privilege escalation paths will help identify similar weaknesses before they are exploited by malicious actors aiming to compromise enterprise commerce systems.
