Description

The VMware vCenter Server installed on the remote host is affected by the following vulnerabilities :

  • An XML external entity (XXE) injection flaw exists in Flex BlazeDS in the file flex-messaging-core.jar due to an incorrectly configured XML parser accepting XML external entities from untrusted sources. A remote attacker can exploit this, via a specially crafted AMF message containing an XML external entity declaration in conjunction with an entity reference, to read arbitrary files and thus gain access to potentially sensitive information. (CVE-2015-3269)

  • A server-side request forgery (SSRF) vulnerability exists in Flex BlazeDS. A remote attacker can exploit this, via a crafted XML document, to direct HTTP traffic to intranet servers, thus bypassing access restrictions and allowing further host-based attacks to be conducted. (CVE-2015-5255)
