HCL BigFix Quantum Risk Analyzer employs a validation process that returns overly detailed error messages when malformed input is encountered. This improper error handling (CWE‑209) can reveal sensitive internal information, enabling attackers to conduct more precise reconnaissance and refine automated fuzzing efforts. The vulnerability does not permit arbitrary code execution or data exfiltration but increases the ease of discovering exploitable paths.

The only product identified as affected is HCL Software’s BigFix Quantum Risk Analyzer. No specific version or release information is supplied, so all deployed instances of this product should be considered potentially impacted until a vendor statement clarifies affected releases.

The CVSS score of 3.9 indicates low severity, and no EPSS score is available; the vulnerability is not listed in CISA’s KEV catalog, suggesting limited known exploitation. Nonetheless, an attacker can exploit it by submitting crafted input to exposed interfaces, causing the application to expose verbose diagnostics. Based on the description, the attack vector is inferred to be remote via any network-facing endpoint that accepts unvalidated input, but the CVE data does not explicitly confirm this route.
