CVE-2026-56567 Overview
CVE-2026-56567 affects HCL iControl v4.3.0. The vulnerability stems from security misconfiguration that exposes internal configuration files to unauthorized local users. Improper web server and application hardening allows a local authenticated attacker with low privileges to access sensitive configuration data.
The issue is mapped to [CWE-15] (External Control of System or Configuration Setting) and results in confidentiality impact without compromising integrity or availability. HCL has published a knowledge base article documenting the issue and remediation steps.
Critical Impact
A local attacker with low privileges can retrieve internal configuration files from HCL iControl v4.3.0, disclosing information that could support further attacks against the application environment.
Affected Products
- HCL iControl v4.3.0
- Deployments with default or hardened-below-baseline web server configurations
- Application instances exposing internal configuration paths

Technical Details for CVE-2026-56567
Vulnerability Analysis
CVE-2026-56567 is a Configuration Information Disclosure issue in HCL iControl v4.3.0. The web server or application layer serves internal configuration files that should never be reachable by end users. Attackers with local, low-privilege access can read these files directly through the application surface.
The disclosed configuration data may include environment settings, service references, or deployment parameters. While the vulnerability does not permit modification or service disruption, exposed configuration content can accelerate reconnaissance and support later stages of an intrusion. HCL has documented the issue in HCL Software Knowledge Base Article KB0132395.
Root Cause
The root cause is improper web server and application hardening. Configuration files that should be restricted by access control lists, file system permissions, or explicit deny rules remain publicly accessible from within the application context. The deployment lacks the hardening baseline required to prevent direct retrieval of internal artifacts.
Attack Vector
Exploitation requires local access to the affected system and low-privilege authentication. An attacker sends direct requests to known or discoverable configuration file paths served by the HCL iControl instance. No user interaction is required, and the attack complexity is low. The vulnerability produces confidentiality impact only.
See the HCL Software Knowledge Base Article for the complete technical description and remediation details.
Detection Methods for CVE-2026-56567
Indicators of Compromise
- Unexpected read access to internal configuration file paths within HCL iControl deployments
- Web server access logs showing requests to configuration file extensions such as .conf, .ini, .xml, or .properties from low-privileged local accounts
- Local user sessions enumerating application directories outside normal workflow patterns
Detection Strategies
- Audit HTTP or application logs for direct requests to configuration resources that fall outside documented application endpoints
- Correlate authenticated low-privilege sessions with file access patterns targeting internal configuration artifacts
- Compare exposed URL paths against an allow list of intended public application routes and flag deviations
Monitoring Recommendations
- Continuously monitor HCL iControl web server access logs for anomalous configuration file retrieval
- Alert on repeated access attempts to configuration paths by the same local account within a short window
- Track file system read events on configuration directories using host-based telemetry
How to Mitigate CVE-2026-56567
Immediate Actions Required
- Review the vendor guidance in HCL Software Knowledge Base Article KB0132395 and apply the recommended hardening steps
- Restrict access to internal configuration files at the web server and file system layers
- Audit local user accounts on HCL iControl v4.3.0 hosts and remove unnecessary low-privilege access
- Verify that no internal configuration paths are reachable through the application front end
Patch Information
HCL has published remediation guidance in HCL Software Knowledge Base Article KB0132395. Administrators should follow the vendor's hardening recommendations for HCL iControl v4.3.0 and confirm that configuration files are no longer exposed after applying changes.
Workarounds
- Configure web server rules to explicitly deny requests to configuration file extensions and directories
- Move sensitive configuration files outside of the web-accessible document root
- Apply strict file system permissions so that only the application service account can read configuration files
- Enable web application firewall rules that block direct requests to known configuration paths
