Hitachi Energy GMS600
View CSAF Summary Hitachi Energy is aware of the vulnerability, CVE-2022-4304 in the OSS component OpenSSL, that affects the GMS600 versions that are listed below. An attacker successfully exploiting this vulnerability could send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection. For immediate mitigation /workaround information, please refer to the General Mitigation Factors/Workarounds The following versions of Hitachi Energy GMS600 are affected: GMS600 vers:GMS600/>=1.3.0|<=1.3.1 (CVE-2022-4304) CVSS Vendor Equipment Vulnerabilities v3 5.9 Hitachi Energy Hitachi Energy GMS600 Observable Discrepancy Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2022-4304 A timing-based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack.
