## Technical details

HCL BigFix Service Management (SM) version 23.0 is affected by an information exposure vulnerability (CWE-200/CWE-522). The flaw occurs during communication between the SM component and internal backend applications, where credentials are insufficiently protected for a short duration. An attacker with the ability to intercept network traffic or monitor internal communications during this window could exfiltrate sensitive credentials. The attack complexity is considered high as it requires precise timing or specific positioning within the network to capture the transient data. HCL has released a security bulletin (KB0128144) addressing this and other vulnerabilities.
