Details

MacCMS10's admin template editor (application/admin/controller/Template.php) blocks dangerous PHP functions in template content via a blacklist regex, but the blacklist omitted exec, passthru, popen, show_source, create_function, register_shutdown_function, register_tick_function, and error_log. Combined with ThinkPHP's {if} template tag, which embeds the condition attribute directly into raw PHP (), an authenticated administrator could inject a payload such as {if condition="exec('id > /tmp/pwned.txt')"}{/if} to achieve remote code execution. Fixed in commit 71ad3bb29570e110d8e973acff68040a3050ddf0 (2026-06-22), which added the missing functions to the filter.

Title

MacCMS10: Incomplete Function Blacklist in Template Editor Enables Authenticated RCE

Summary

MacCMS10's admin template editor (application/admin/controller/Template.php) blocks dangerous PHP functions in template content via a blacklist regex, but the blacklist omitted exec, passthru, popen, show_source, create_function, register_shutdown_function, register_tick_function, and error_log. Combined with ThinkPHP's {if} template tag, which embeds the condition attribute directly into raw PHP (<?php if(condition): ?>), an authenticated administrator could inject a payload such as {if condition="exec('id > /tmp/pwned.txt')"}{/if} to achieve remote code execution. Fixed in commit 71ad3bb29570e110d8e973acff68040a3050ddf0 (2026-06-22), which added the missing functions to the filter.
