CVE-2024-9593: Time Clock <= 1.2.2 & Time Clock Pro <= 1.1.4 - Remote Code Execution

id: CVE-2024-9593

info:
  name: Time Clock <= 1.2.2 & Time Clock Pro <= 1.1.4 - Remote Code Execution
  author: s4e-io
  severity: high
  description: |
    The Time Clock plugin and Time Clock Pro plugin for WordPress are vulnerable to Remote Code Execution in versions up to, and including, 1.2.2 (for Time Clock) and 1.1.4 (for Time Clock Pro) via the 'etimeclockwp_load_function_callback' function. This allows unauthenticated attackers to execute code on the server. The invoked function's parameters cannot be specified.
  impact: |
    Unauthenticated attackers can execute limited PHP functions on the server through the etimeclockwp_load_function_callback function, potentially exposing sensitive system information through phpinfo and other callable functions.
  remediation: |
    Update Time Clock plugin to a version later than 1.2.2 or Time Clock Pro plugin to a version later than 1.1.4 to address the remote code execution vulnerability.
