HCL BigFix Service Management is affected by a Sensitive Information Leakage vulnerability, which could allow an unauthenticated attacker to extract internal IP addresses from the application's responses, enabling them to map the underlying network topology and identify potential internal targets.
AnalysisAI
HCL BigFix Service Management exposes internal IP addresses through its own HTTP responses - response headers, error messages, or rendered page content - allowing anyone able to reach the instance to harvest RFC1918 addressing and infer the internal network topology behind it. The consequence is reconnaissance only: no data modification, no service disruption, and a low vendor base score of 3.1, making this a low-priority item rather than an urgent one. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to an HCL BigFix Service Management instance whose HTTP responses (headers, error messages, or page content) embed internal IP addresses; the attacker simply inspects those responses to harvest RFC1918 topology data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a low-severity information-disclosure issue and clearly a low priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch was identified at time of analysis; consult HCL advisory KB0133917 (https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0133917) for the current fixed build and upgrade as soon as one is published, since patching is the only way to stop the application itself from emitting internal addresses. … Detailed patch versions, workarounds, and compensating controls in full report. |
