Description
***********
Textpattern system has multiple security vulnerabilities:
1. Parameter Value Overflow

3. XSS in POST
4. Stored XSS
5. Insecure password changing algorithm
Details
*******
1. Parameter Value Overflow
Vulnerability found in script index.php in comments section. Post parameter
"message".
The application does not ensure that the parameter value length. It can be
used for performing a DOS attack.
Example:
message = [A]x10000
------------------------------------------------------------------------
--------------------
2. Linked XSS vulnerability found in /textpattern/setup/index.php, attacker
can inject XSS in URL string.
Example:
http://[server]/[installdir]/textpattern/setup/index.php/"><script>alert
('DSecRG XSS')</script>
------------------------------------------------------------------------
--------------------
3. XSS in POST
Vulnerability found in script index.php in comments section. Post parameter
"name".
Example:
name = <img src="javascript:alert('DSecRG XSS')">
name = <script>alert('DSecRG XSS')</script>
------------------------------------------------------------------------
--------------------
4. Stored XSS
Vulnerability found in script textpattern/index.php?event=article in post
parameter "Body".
Example:
Body = <IMG SRC=javascript:alert("DSecRG_XSS")>
------------------------------------------------------------------------
--------------------
5. Insecure password changing algorithm

change admin password without knowing old password.
It will be more secure to ask old password when changing password or
primary email.
