An issue was discovered in the Popup Maker plugin before 1.8.13 for WordPress. An unauthenticated attacker can partially control the arguments of the do_action function to invoke certain popmake_ or pum_ methods, as demonstrated by controlling content and delivery of popmake-system-info.txt (aka the "support debug text file").

  • Detect unauthenticated GET requests to the system info tab endpoint via the pum_action parameter
  • Detect unauthenticated POST requests invoking the popup_sysinfo action via the popmake_action parameter
  • Confirm exploitation by checking response body for 'Popup Maker Configuration' and 'Webserver Configuration' strings, indicating system info disclosure
  • Identify vulnerable WordPress installations by fingerprinting the popup-maker plugin path in HTML responses
  • ·The vulnerability affects Popup Maker plugin versions before 1.8.13; the template title references 1.8.12 as the fix version but NVD states the fix is in 1.8.13
  • ·The attacker can only *partially* control the do_action arguments, limiting which popmake_/pum_ methods can be invoked
