CVE-2025-52650 identifies a vulnerability in HCL AION version 2.0 related to improper enforcement of Content Security Policy (CSP), specifically allowing inline script execution. CSP is a critical security mechanism designed to prevent cross-site scripting (XSS) and related code injection attacks by restricting the sources from which scripts can be loaded and executed. The vulnerability falls under CWE-1032, which concerns CSP bypasses. In this case, the CSP implemented by HCL AION 2.0 is insufficiently restrictive, permitting attackers to inject and execute inline scripts despite CSP rules intended to block such behavior. This flaw enables attackers to execute arbitrary JavaScript in the context of the affected web application, potentially leading to unauthorized actions, data manipulation, or further exploitation. The CVSS v3.1 score of 8.2 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact metrics show low confidentiality impact (C:L), high integrity impact (I:H), and no availability impact (A:N). No known exploits are currently in the wild, but the vulnerability's nature and ease of exploitation make it a significant risk. The lack of available patches at the time of publication necessitates immediate interim mitigations. This vulnerability primarily threatens web applications built on HCL AION 2.0, which may be used in enterprise environments for process automation and digital transformation.

For European organizations, the vulnerability poses a significant risk to the integrity of web applications built on HCL AION 2.0. Successful exploitation can allow attackers to execute malicious scripts, potentially leading to unauthorized data modification, session hijacking, or further compromise of internal systems. Although confidentiality impact is rated low, the integrity impact is high, which can undermine trust in business processes and data accuracy. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit. Given the widespread use of HCL enterprise products in sectors such as finance, manufacturing, and government across Europe, exploitation could disrupt critical business operations and lead to regulatory compliance issues under GDPR if personal data integrity is affected. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score and CSP bypass nature indicate that the threat could escalate rapidly once weaponized. Availability is not impacted, so denial-of-service is unlikely, but the integrity compromise alone is sufficient to cause serious operational and reputational damage.

1. Monitor HCL’s official channels closely for the release of security patches addressing CVE-2025-52650 and apply them immediately upon availability. 2. In the interim, review and harden CSP configurations in affected applications to explicitly disallow 'unsafe-inline' scripts and avoid using nonce or hash bypasses that could be exploited. 3. Implement Web Application Firewalls (WAF) with rules to detect and block inline script injections and anomalous script execution patterns. 4. Employ Runtime Application Self-Protection (RASP) solutions that can detect and prevent unauthorized script execution at runtime. 5. Conduct security awareness training to reduce the risk of successful user interaction-based exploitation, emphasizing phishing and social engineering defenses. 6. Audit all web applications built on HCL AION 2.0 for CSP policy weaknesses and remediate any deviations from best practices. 7. Use Content Security Policy reporting features to monitor and analyze CSP violations to detect potential exploitation attempts. 8. Limit exposure of HCL AION-based applications to only necessary users and networks, employing network segmentation and access controls. 9. Review and update incident response plans to include scenarios involving CSP bypass and script injection attacks.
