Technical details
HCL MyCloud version 10.8.2 is vulnerable to information exposure (CWE-200) via server version disclosure. An attacker with high privileges can remotely access version strings that identify the underlying software components. This metadata leak reduces the effort required for reconnaissance and allows an attacker to map the environment against known CVEs for those specific versions. The vulnerability is rated low severity because it requires high privileges and does not directly result in data modification or service disruption.
