CVE-2025-55272 Overview
HCL Aftermarket DPC is affected by a Banner Disclosure vulnerability that allows attackers to gain insights into the system's software and version details. This information disclosure issue enables threat actors to craft software-specific attacks by leveraging exposed banner information that reveals technical details about the underlying application infrastructure.
Critical Impact
Attackers can enumerate software versions and system details to plan targeted attacks against known vulnerabilities in specific versions of HCL Aftermarket Cloud.
Affected Products
- HCL Aftermarket Cloud version 1.0.0
- HCL Aftermarket DPC (Dealer Parts Catalog)

Technical Details for CVE-2025-55272
Vulnerability Analysis
This vulnerability falls under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The issue stems from the application exposing software identification banners that reveal version information and potentially other system details to unauthenticated remote attackers. When server responses or error messages contain verbose information about the underlying software stack, attackers can fingerprint the application and identify known vulnerabilities specific to those versions.
Banner disclosure vulnerabilities, while often considered lower severity, serve as a critical reconnaissance tool for attackers. By knowing the exact software version, threat actors can consult public vulnerability databases to find exploitable weaknesses, significantly reducing the time and effort required to compromise a system.
Root Cause
The root cause of this vulnerability is insufficient information exposure controls within the HCL Aftermarket DPC application. The system fails to properly sanitize or suppress software identification information in HTTP response headers, error pages, or other communication channels that are accessible to unauthenticated users over the network.
Attack Vector
The attack vector is network-based and requires no authentication or user interaction. An attacker can remotely query the HCL Aftermarket Cloud application to extract banner information through various techniques:
The vulnerability can be exploited through standard HTTP requests that elicit responses containing server identification headers, application version strings, or verbose error messages. Attackers typically use automated scanning tools to enumerate web applications and extract banner information from response headers such as Server, X-Powered-By, or custom application headers that reveal version details.
Once obtained, this information allows attackers to search for known CVEs affecting the specific software versions, craft targeted exploits, or identify attack paths based on default configurations associated with particular releases.
Detection Methods for CVE-2025-55272
Indicators of Compromise
- Unusual patterns of HTTP requests targeting error pages or non-existent endpoints to trigger verbose error responses
- Repeated requests from single IP addresses attempting to enumerate server headers and application responses
- Scanning activity targeting common banner disclosure vectors such as /version, /status, or administrative endpoints
Detection Strategies
- Monitor HTTP response headers for sensitive version information being transmitted to external clients
- Implement web application firewall (WAF) rules to detect and log reconnaissance scanning patterns
- Review access logs for systematic probing of endpoints that may reveal system information
- Configure intrusion detection systems to alert on known vulnerability scanner signatures
Monitoring Recommendations
- Enable detailed logging on the HCL Aftermarket Cloud application to capture all incoming requests and response headers
- Implement rate limiting and anomaly detection to identify potential scanning activity
- Regularly audit HTTP responses to ensure no sensitive version or configuration information is being exposed
- Monitor for external reconnaissance tools targeting your application infrastructure
How to Mitigate CVE-2025-55272
Immediate Actions Required
- Review and disable verbose server banners in HTTP response headers
- Configure the application server to suppress software version information in responses
- Implement generic error pages that do not reveal system internals or version details
- Apply vendor-recommended security configurations from the HCL knowledge base article
Patch Information
HCL Software has published guidance for this vulnerability. Administrators should consult the HCL Software Knowledge Base Article for official remediation instructions and any available patches or configuration updates.
Workarounds
- Configure web server settings to remove or obfuscate Server and X-Powered-By headers
- Implement a reverse proxy or WAF in front of the application to strip identifying headers before responses reach clients
- Customize error pages to display generic messages without revealing application stack information
- Restrict access to administrative or diagnostic endpoints that may expose system details
# Example: Suppressing server headers in Apache configuration
# Add to httpd.conf or .htaccess
ServerTokens Prod
