Executive brief
HCL BigFix Service Management, a tool used for managing IT services and infrastructure, contains a vulnerability where login credentials are not adequately protected during communication with internal backend systems. For a brief period during these data transfers, the credentials could be exposed. If an attacker manages to intercept this information, they could potentially gain unauthorized access to the system or misuse the stolen credentials.
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.
