Server version disclosure to privileged remote users

Published Jul 21, 2026 · Updated Jul 21, 2026

HCLSoftware has not disclosed which response, header, or interface returns the version, or what operation exposes it. High-privilege access and high-complexity conditions are required; the disclosed identifier supports targeted selection of known server flaws but does not itself modify data or interrupt service.
