Hitachi Energy issued a security alert regarding unauthenticated servlet access vulnerabilities affecting its Asset Suite software. CISA Alerts reported that hackers could exploit these vulnerabilities to impact the confidentiality, integrity, and availability of affected systems. [1]

The security flaw specifically involves the HTTPPublishAdapterTestServlet component, which was originally intended for testing purposes. Unauthenticated users are able to access this servlet without proper authorization checks. [1]

Hitachi was founded in 1910 by engineer Namihei Odaira as an electrical machinery manufacturing unit before becoming an independent business in 1920. The Japanese multinational conglomerate is headquartered in Tokyo. [2]

Hitachi Energy advises organizations to update or upgrade to Asset Suite version 9.9.1 as soon as it becomes available. As an immediate mitigation step, administrators should disable the affected test servlet. [1]
