Hi,
Here's the vulnerabilities descriptions and POCs:
#################################
I write to report three vulnerabilities that I found in the last version
of Aardvark Topsites PHP(5.2.1) and older versions.
The cause of all of them is the incorrect verification of input parameters.
Here are the vulnerabilities:
==================
HTML Injection (up to 5.2.0)
--------------------------
For example, is possible to inject a link to any URL with any anchor text.
POC:
/index.php?a=search&q=psstt+security”><a+href%3Dhttp%3A%2F%2Fwebsec.id3as.com>Web-Application-Security
Information Disclosure 1 (up to 5.2.1)
--------------------------
Disclosure of full path of the application sources when you put a
negative number at the ’start’ parameter.
POC: /index.php?a=search&q=psstt&start=-4
Information Disclosure 2 (up to 5.2.0)
--------------------------
Disclosure of full path of the application sources and some source code
too when you put an non-existent user at ‘u’ parameter.
POC: /index.php?a=rate&u=nonexistentuser
==================
I created a page with the details and possible updates at:
http://websec.id3as.com/aardvark-topsites-php-521-security-vulnerabilities-disclosure/
Feel free to ask me any question about this to properly report this
vulnerabilities.
Google Dork: "Powered by Aardvark Topsites PHP 5.2.0"
(or 5.2.1 for the last version)
