Horizon Alert
Summary of the vulnerability and why it matters
A business logic vulnerability in HCL Aftermarket EPC could allow unauthorized users to obtain passwords from the server and have them sent to their own email addresses. This occurs because the application does not consistently validate user input, specifically when handling email requests for password delivery.
- Passwords could be sent to unauthorized email addresses.
- Affects systems managing user accounts and credentials.
- Confirm relevance and exposure of this system.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending a crafted email request to the application. While the application checks user IDs, it does not adequately validate email addresses when sending password reset information. This allows a non-valid user to intercept passwords and redirect them to their own email address, potentially leading to account compromise.
- Attacker has network access.
- Manipulating email requests for password resets.
- Leads to credential theft and account takeover.
Live Threat
Current exploitation, exposure, and threat context
A non-authenticated user could potentially retrieve passwords stored on the server and redirect them to an attacker-controlled email address by exploiting a lack of validation during password reset requests. This could occur when the application fails to properly validate email requests for sending password reset information.
- Server-stored passwords
- Manipulating email requests
- Unauthorized password access
Operational Fix
Recommended remediation, mitigation, and detection steps
The identified business logic vulnerability in HCL Aftermarket EPC requires immediate attention from teams responsible for application security and management. The first practical step is to locate all instances of the affected application, determine their exposure (whether they are internet-facing or internal but critical), and identify the specific business or IT owner accountable for each instance before planning remediation.
- Application owners should lead remediation efforts.
- Verify application reachability and business criticality first.
- Plan remediation based on exposure and business impact.
