> CISA clarifies that reported vulnerabilities do not affect Hitachi Energy MSM; no customer action required.

Hitachi Energy and CISA have issued an advisory clarifying that public reports of vulnerabilities initially believed to affect certain versions of Hitachi Energy MSM have been determined not to apply to the product following technical analysis and validation. Two CVEs were initially referenced: CVE-2024-2398, a memory leak in libcurl when HTTP/2 server push headers exceed limits, and CVE-2019-5097, a denial-of-service vulnerability in GoAhead web server affecting multi-part/form-data request processing. Neither vulnerability affects MSM.

This advisory represents a remediation or clarification of earlier reports rather than an active threat to MSM deployments. The guidance emphasizes general hardening practices: MSM should not be internet-facing, and defenders should ensure user access controls, antivirus signatures, and OS hardening per CIS benchmarks on systems running the MSM Client application. No patching is required.

The advisory is a CISA republication of Hitachi Energy's vendor security advisory and carries no active exploitation signal.
