Admin command execution via notification template evaluation
Published Jul 21, 2024 · Updated Aug 1, 2024
Code injection in Flute CMS 0.2.2.4-alpha allows remote authenticated users to execute operating-system commands through notification content. ContentParser.php replaceContent extracts brace-delimited expressions and passes their method names and arguments to evaluateExpression, which invokes them instead of limiting substitutions to approved fields. Administrator access is required to create the malicious notification, and a later notification trigger executes the command and exposes its output.
