ZDI-20-1102: NEC ExpressCluster ApplyConfig XML External Entity Processing Information Disclosure Vulnerability
This vulnerability allows remote attackers to disclose sensitive information on affected installations of NEC ExpressCluster. Authentication is not required to exploit this vulnerability. The specific flaw exists within the clpwebmc executable. Due to the improper restriction of XML External Entity (XXE) references, a specially-crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of SYSTEM.
