#9734 closed defect (fixed)

DOM injection vulnerability in NoteBox.expand_macro()

Reported by: Alex Willmer Owned by: Ryan J Ollos
Priority: high Component: NoteBoxMacro
Severity: critical Keywords: security
Cc: Ryan J Ollos Trac Release: 0.11

Description

NoteBox.expand_macro() performs string concatenation to construct a div element, as result it is possible to inject javascript into the page and have it executed. The following invocation demonstrates this: 

[[NoteBox("></div><script type="text/javascript">alert("Javacript Injection Ahoy!")</script><div class="noteboxwarn, Don't care about this text)]]

Attached is a patch that removes the use of StringIO and should make the macro safe for use.
