CVE-2024-23564 in Aftermarket EPC
Summary
by MITRE • 07/17/2026
HCL Aftermarket EPC is affected by Business Logic Vulnerability using which a non valid user of the application can obtain passwords from the server and redirect them to their own email address by manipulating the server's response. The application includes checks in the initial requests to verify the validity of the provided UserId, but similar validation is not applied to Email requests when sending passwords to user emails.

This vulnerability represents a critical business logic flaw that undermines the authentication and authorization mechanisms of the HCL Aftermarket EPC application. The security weakness stems from inconsistent validation controls where initial user authentication checks are properly implemented for UserId verification but fail to extend to email-related operations during password recovery processes. This discrepancy creates an exploitable gap that allows unauthorized individuals to bypass normal access controls and manipulate the system's response handling. The vulnerability specifically targets the password recovery functionality, enabling malicious actors to extract sensitive credentials from the server infrastructure and redirect them to arbitrary email addresses controlled by the attacker.
The technical implementation of this business logic flaw demonstrates a failure in input validation and response handling protocols that directly violates established security principles. When legitimate users request password resets, the system properly validates their UserId against authorized records, but during subsequent email delivery operations, no equivalent validation occurs for the target email address. This inconsistent approach creates multiple attack vectors where an unauthenticated user can manipulate server responses to intercept or redirect password reset emails. The vulnerability operates at the application layer and leverages weak boundary checking mechanisms that should enforce consistent validation across all user interaction points within the authentication flow.
The operational impact of this vulnerability extends beyond simple credential theft to encompass potential account takeover scenarios and data exfiltration risks. Attackers can exploit this flaw to systematically harvest user credentials from the server, potentially gaining access to multiple accounts within the application ecosystem. The redirection capability provides attackers with additional attack surface for social engineering campaigns or credential stuffing attacks against other systems where users may have reused passwords. This vulnerability also creates audit trail complications as legitimate password reset requests may be compromised, making it difficult for security teams to distinguish between authorized and malicious activities.
Organizations should implement comprehensive input validation controls that enforce consistent validation mechanisms across all user interaction points within the application's authentication framework. The solution requires implementing robust email address validation during password recovery operations, including verification against approved recipient lists or implementing rate limiting controls to prevent abuse. Security measures should include monitoring for unusual patterns in password reset requests and implementing proper access logging that tracks all email delivery operations. This remediation approach aligns with cwe-284 access control vulnerabilities and addresses attack techniques categorized under mitre att&ck tactic privilege escalation through improper input validation. Organizations must also establish proper session management controls to ensure that unauthorized users cannot manipulate server responses or redirect authentication flows. The implementation of these controls should follow industry standards including owasp top ten security controls and nist cybersecurity framework guidelines for robust application security posture development.
