CVE-2024-51567: CyberPanel v2.3.6 Pre-Auth Remote Code Execution

id: CVE-2024-51567

info:
  name: CyberPanel v2.3.6 Pre-Auth Remote Code Execution
  author: DhiyaneshDK
  severity: critical
  description: |
    upgrademysqlstatus in databases/views.py in CyberPanel (aka Cyber Panel) before 5b08cd6 allows remote attackers to bypass authentication and execute arbitrary commands via /dataBases/upgrademysqlstatus by bypassing secMiddleware (which is only for a POST request) and using shell metacharacters in the statusfile property, as exploited in the wild in October 2024 by PSAUX. Versions through 2.3.6 and (unpatched) 2.3.7 are affected.
  impact: Attackers can exploit this vulnerability by crafting malicious requests that bypass authentication controls, allowing them to inject and execute arbitrary commands on the underlying server.
