HCL BigFix Service Management is affected by a Security Misconfiguration vulnerability, which could allow an authenticated attacker to exploit improper access controls, enabling the unauthorized viewing of restricted data elements across tenant boundaries.
AnalysisAI
Cross-tenant data exposure in HCL BigFix Service Management allows an authenticated user with a valid account in one tenant to read restricted data elements belonging to other tenants because of improper access controls. Affected deployments are those operated in shared or multi-tenant mode; the impact is limited to confidentiality (unauthorized viewing), with no modification or disruption of data, and no user interaction is required on the victim's side (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N, base 5.0). …

Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated account (PR:L) on a multi-tenant HCL BigFix Service Management deployment; the attacker abuses improper access controls to read restricted data elements belonging to other tenants across the tenant boundary. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but modest-severity confidentiality issue, not a high-priority emergency. … 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 version is identified in the provided data, so administrators must confirm fix availability directly with HCL through the advisory at https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0133917 before assuming any release is remediated. … Detailed patch versions, workarounds, and compensating controls in full report. |
