1. Description:
|
|
Adds a new section to user profiles that will display their last posts.
|
|
|
|
|
|
2. Proof of Concept:
|
|
|
|
Persistent XSS
|
|
- Create a thread with the following subject <script>alert('XSS')</script>
|
|
- Now visit your profile to see the alert.
|
|
|
|
|
|
3. Solution:
|
|
I reported the plugin twice over the past 3 weeks and recieved no response.
|
|
|
|
|
|
The following should be added in line 236 to properly sanitize thread subjects.
|
|
|
|
$d['tsubject'] = htmlspecialchars_uni($d['tsubject']); |
