Lifecycle Timeline
3Description
HCL Aftermarket DPC is affected by Cross Domain Script Include vulnerability where an attacker using external scripts can tamper with the DOM, altering the content or behavior of the application. Malicious scripts can steal cookies or session tokens, leading to session hijacking.
Analysis
HCL Aftermarket DPC is vulnerable to Cross Domain Script Include (CWE-829) that permits unauthenticated remote attackers to inject and execute malicious external scripts, enabling DOM tampering and theft of session credentials without user interaction. Affected versions include Aftermarket DPC 1.0.0. No public exploit code or active exploitation has been identified at time of analysis, though the attack vector is network-accessible and requires only user interaction (rendering this a moderate-impact integrity threat rather than a critical one).
Technical Context
The vulnerability stems from improper validation of external script sources, classified under CWE-829 (Inclusion of Functionality from Untrusted Control Sphere). HCL Aftermarket DPC fails to enforce Content Security Policy (CSP) headers or same-origin policy protections, allowing attackers to include arbitrary JavaScript from external domains. When a user visits the affected application, malicious scripts execute in the application's security context, gaining access to the DOM, cookies, and session storage. The affected product is identified via CPE cpe:2.3:a:hcl:aftermarket_dpc:*:*:*:*:*:*:*:*, confirming the vulnerability affects the HCL Aftermarket DPC product line across potentially multiple versions, though specific version information is limited to 1.0.0 in the EUVD record.
Affected Products
HCL Aftermarket DPC version 1.0.0 is confirmed affected per the EUVD record (EUVD-2025-209069). The CPE designation cpe:2.3:a:hcl:aftermarket_dpc:*:*:*:*:*:*:*:* indicates the vulnerability may affect other versions of the product line, though specific version boundaries have not been publicly disclosed. Consult HCL's security advisory at https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0129793 for a definitive list of affected and patched versions.
Remediation
Contact HCL Software for patch availability and version information via the security advisory at https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0129793. Pending patch deployment, implement Content Security Policy (CSP) headers with 'script-src self' to restrict script execution to same-origin scripts only, enforce HTTPS with HSTS to prevent man-in-the-middle injection, and consider deploying a Web Application Firewall (WAF) to filter malicious external script requests. Network-level access controls limiting application access to trusted IP ranges will reduce exposure.
