CVE-2025-15236 identifies an Absolute Path Traversal vulnerability (CWE-36) in the QOCA aim AI Medical Cloud Platform developed by Quanta Computer. This vulnerability allows an authenticated remote attacker to specify arbitrary file system paths and read folder names under those paths. The flaw arises due to insufficient validation or sanitization of user-supplied file path inputs, enabling traversal outside intended directories. The attacker must have authenticated access with low privileges, but no additional user interaction is required. The vulnerability has a CVSS 4.0 score of 5.3, reflecting medium severity, with a vector indicating network attack vector, low attack complexity, no privileges required beyond authentication, no user interaction, and low impact on confidentiality. Although no known exploits are reported in the wild, the ability to enumerate directory structures can facilitate further attacks such as information disclosure, reconnaissance, or privilege escalation. The QOCA aim platform is used in medical cloud environments, making this vulnerability particularly sensitive due to potential exposure of healthcare-related data or system configurations. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. The vulnerability was reserved at the end of 2025 and published in early 2026, indicating recent discovery and disclosure.

For European organizations, particularly those in the healthcare sector using the QOCA aim AI Medical Cloud Platform, this vulnerability poses a risk of unauthorized information disclosure. Attackers can enumerate directory structures, potentially revealing sensitive configuration files, patient data directories, or system internals. This exposure can aid in crafting more targeted attacks, including privilege escalation or lateral movement within the network. Given the critical nature of healthcare data and strict regulatory frameworks such as GDPR, even indirect data exposure can have severe compliance and reputational consequences. The medium severity rating reflects limited direct data exposure but significant potential for enabling further exploitation. The requirement for authentication limits the attack surface but does not eliminate risk, especially if credential compromise occurs. The absence of known exploits reduces immediate risk but does not preclude future exploitation. European healthcare providers and cloud service operators must consider the impact on confidentiality and operational integrity.

To mitigate CVE-2025-15236, organizations should implement strict input validation and sanitization on all file path parameters to prevent traversal sequences (e.g., '../'). Enforce robust access controls ensuring users can only access directories and files within their authorized scope. Employ application-layer whitelisting of allowed paths and deny all others. Monitor logs for unusual file path access patterns indicative of traversal attempts. If possible, isolate the QOCA aim platform in segmented network zones with limited access. Regularly update and patch the platform once vendor fixes become available. Conduct thorough security assessments and penetration testing focusing on file system access controls. Educate administrators on the risks of path traversal and the importance of credential security to prevent unauthorized authentication. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block path traversal payloads. Finally, maintain incident response readiness to quickly address any exploitation attempts.
