CVE-2025-55250 identifies a vulnerability in HCL Software's AION version 2 where error messages generated by the system disclose sensitive technical information, classified under CWE-209 (Generation of Error Message Containing Sensitive Information). This vulnerability arises when the software fails to properly sanitize or restrict the content of error messages, potentially exposing internal system details such as configuration data, file paths, or stack traces. Although the CVSS v3.1 base score is low (1.8), reflecting limited impact and high exploitation complexity, the presence of sensitive information in error messages can aid attackers in reconnaissance and crafting targeted attacks. The CVSS vector indicates that exploitation requires local access (AV:L), high attack complexity (AC:H), high privileges (PR:H), and user interaction (UI:R), which significantly reduces the likelihood of exploitation. The vulnerability does not directly affect confidentiality, integrity, or availability but may indirectly assist attackers by revealing system internals. No patches or known exploits are currently available, and the vulnerability was published in January 2026. Organizations running HCL AION version 2 should audit error handling mechanisms and restrict access to systems to mitigate potential risks.

For European organizations, the direct impact of CVE-2025-55250 is limited due to the low severity and high exploitation requirements. However, the disclosure of sensitive technical details through error messages can facilitate reconnaissance activities by attackers, potentially leading to more sophisticated attacks if combined with other vulnerabilities. Organizations in sectors relying on HCL AION for critical business processes, such as finance, manufacturing, or government services, could face increased risk if attackers leverage this information to escalate privileges or bypass security controls. The vulnerability's requirement for local high-privilege access and user interaction limits remote exploitation, reducing the threat surface. Nonetheless, in environments where insider threats or compromised privileged accounts exist, this vulnerability could aid attackers in lateral movement or privilege escalation. Therefore, while the immediate risk is low, the vulnerability should be addressed to maintain a robust security posture.

To mitigate CVE-2025-55250, European organizations should implement the following specific measures: 1) Review and harden error handling configurations in HCL AION version 2 to ensure error messages do not expose sensitive technical details; customize error messages to be generic and avoid revealing internal system information. 2) Restrict local access to systems running AION to trusted administrators only, enforcing the principle of least privilege and using strong authentication mechanisms. 3) Monitor and audit logs for unusual error message patterns or unauthorized access attempts that could indicate exploitation attempts. 4) Implement network segmentation and access controls to limit the ability of attackers to gain local access or interact with the system. 5) Stay informed about vendor updates and apply patches promptly once available, as no patch is currently released. 6) Conduct security awareness training for privileged users to reduce the risk of social engineering or accidental triggering of error conditions. These targeted actions go beyond generic advice by focusing on error message management and access control specific to the affected product and vulnerability.
