CVE-2026-56571: HCL iControl sensitive information disclosure via improper error handling

CVE-2026-56571 · Severity: low · CVSS 3.7 · Published 2026-07-31

Executive brief

HCL iControl, a business process monitoring and visibility platform, is affected by a security vulnerability where the system may reveal sensitive technical information when errors occur. Under certain conditions like network timeouts or database failures, the application might display detailed error messages that could help an attacker understand the internal workings of the system. While this does not directly allow an attacker to take over the system, it provides information that could be used to plan more sophisticated attacks.

Technical details

HCL iControl versions 4.3.0 and 4.4.0 are vulnerable to CWE-209 (Generation of Error Message Containing Sensitive Information). The application fails to properly sanitize error outputs during various failure states, including out-of-memory conditions, null pointer exceptions, system call failures, and database or network timeouts. An unauthenticated remote attacker can potentially trigger these conditions to receive verbose error messages containing technical details about the environment or application logic. The attack complexity is considered high as it requires specific environmental conditions to trigger the informative leaks. Mitigation typically involves configuring the application to return generic error messages to users while logging detailed stack traces internally.
