CVE-2024-23578Network attack vector

Data exposure and modification via wildcard CORS

Published Jul 17, 2026 · Updated Jul 17, 2026

Permissive CORS in HCLSoftware Aftermarket EPC 1.0.0 allows remote attackers to read or modify application data through a victim's browser. The affected request returns a wildcard cross-origin policy that trusts every domain, allowing browser scripts from untrusted origins to read responses and submit requests. Exploitation requires a user to visit attacker-controlled content while the browser can reach the application; no service interruption is reported.
