CVE-2025-2236 is a vulnerability identified in OpenText Advanced Authentication versions prior to 6.5. It is categorized under CWE-497, which involves the exposure of sensitive system information to an unauthorized control sphere. This vulnerability allows an attacker to elicit sensitive information during the management and configuration of external services within the Advanced Authentication platform. The exposure could include configuration details, system parameters, or other sensitive metadata that could aid an attacker in further compromising the system or understanding its security posture. The vulnerability has a CVSS 4.0 base score of 2.1, indicating a low severity level. The vector details show that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The scope is partial (S:P), and the vulnerability is exploitable remotely (AU:N) with medium remediation effort (RE:M). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability primarily concerns information disclosure rather than direct system compromise or denial of service, but it can provide attackers with valuable intelligence to facilitate further attacks.

For European organizations using OpenText Advanced Authentication, this vulnerability could lead to unauthorized disclosure of sensitive system information during configuration and management of external services. Such information leakage can undermine the confidentiality of security configurations and potentially expose details about authentication mechanisms, integration points, or system architecture. While the direct impact on system integrity and availability is low, the information gained could enable attackers to craft more targeted attacks, escalate privileges, or bypass security controls. This is particularly critical for organizations in regulated sectors such as finance, healthcare, and government, where authentication systems are a key security component. The low CVSS score suggests limited immediate risk, but the potential for information elicitation could have cascading effects on the security posture if combined with other vulnerabilities or attack vectors.

European organizations should prioritize upgrading OpenText Advanced Authentication to version 6.5 or later, where this vulnerability is addressed. In the absence of an official patch, organizations should restrict local access to systems running the vulnerable software to trusted administrators only, implementing strict access controls and monitoring. Configuration management interfaces should be secured with multi-factor authentication and network segmentation to limit exposure. Regular audits of authentication system configurations and logs can help detect unauthorized access attempts. Additionally, organizations should review and harden the management of external services integrated with Advanced Authentication to minimize sensitive information exposure. Employing network-level protections such as host-based firewalls and intrusion detection systems can further reduce the attack surface. Finally, maintaining up-to-date threat intelligence and monitoring for any emerging exploits related to this vulnerability is advisable.
