CVE-2024-23578 in Aftermarket EPC
Summary
by MITRE • 07/17/2026
HCL Aftermarket EPC is vulnerable to attack as the application implements an HTML5 cross-origin resource sharing (CORS) policy for this request that allows access from any domain (*-Wildcard).

The HCL Aftermarket EPC vulnerability represents a critical security flaw in the application's cross-origin resource sharing implementation that exposes the system to unauthorized access and potential exploitation. This weakness stems from the application's overly permissive CORS policy configuration that permits requests from any domain through the use of wildcard characters, creating an insecure communication channel that violates fundamental web security principles.
The technical nature of this vulnerability resides in the improper enforcement of CORS policies within the HCL Aftermarket EPC application. When an application implements CORS with a wildcard domain specification such as "*", it allows any origin to make requests to the server without proper authorization checks. This configuration creates a pathway for malicious actors to craft cross-origin requests that can bypass normal security boundaries and access sensitive resources or functionality that should be restricted to legitimate users or applications.
From an operational perspective, this vulnerability presents significant risks to organizations using HCL Aftermarket EPC as it enables attackers to perform cross-site request forgery attacks, steal sensitive data, or manipulate application functionality through unauthorized cross-origin requests. The impact extends beyond simple data exposure since the wildcard CORS policy effectively removes any protection against malicious domains attempting to interact with the application's resources, potentially allowing for complete compromise of the system's security posture.
The vulnerability aligns with CWE-346, which specifically addresses "Origin Validation Error" in web applications where the application fails to properly validate the origin of cross-origin requests. This weakness creates opportunities for attackers to leverage the CORS misconfiguration to perform malicious activities such as data exfiltration, privilege escalation, or unauthorized access to protected resources within the application environment. The risk is amplified by the fact that CORS policies are typically configured at the server level and require careful implementation to prevent such broad access permissions.
Organizations should implement immediate mitigations including replacing wildcard CORS configurations with explicit domain whitelisting, implementing proper origin validation checks, and ensuring that CORS policies are aligned with the principle of least privilege. The recommended approach involves configuring specific allowed origins rather than using wildcards, implementing additional authentication mechanisms for cross-origin requests, and conducting regular security assessments to identify similar misconfigurations throughout the application stack. This remediation strategy aligns with ATT&CK technique T1566 which focuses on social engineering through spearphishing attacks that can exploit such CORS vulnerabilities to gain unauthorized access to target systems.
Security teams must also consider implementing additional monitoring controls to detect unusual cross-origin requests and establish proper access control mechanisms that prevent unauthorized domains from interacting with the application's resources. The implementation of Content Security Policy headers alongside proper CORS configuration provides layered defense against potential exploitation attempts while ensuring that legitimate applications can continue to function properly within the defined security boundaries.
