CVE-2024-23569 describes a vulnerability in HCL Aftermarket EPC where the server does not set the 'X-XSS-Protection' HTTP header. This header is designed to enable the browser's built-in XSS filtering capabilities to block or sanitize reflected XSS attacks. The absence of this header means that the browser's XSS filter may not be activated, potentially allowing some cross-site scripting attacks to succeed. The vulnerability is categorized under CWE-692, which relates to incomplete denial of requests to insecure resources. There is no vendor advisory or patch information available, and no known exploits in the wild have been reported.

The impact is limited to a reduced ability to mitigate reflected cross-site scripting attacks via browser XSS filters. Confidentiality may be slightly affected (low impact), but integrity and availability are not impacted. The CVSS vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, low confidentiality impact, and no integrity or availability impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the absence of an official fix, users should consider implementing alternative XSS protections such as Content Security Policy (CSP) headers and input validation. Monitoring vendor communications for updates is recommended.
