Pritlog v0.821 CMS - Multiple Web Vulnerabilities
PRITLOG is an extremely simple, small (< 500K uncompressed) and powerful blog system. It does not use or need
a MYSQL database and fully works based on Sqlite. Sqlite is very similar to flat files and does not need any
server setup and comes as default with most PHP5 installations. Just drop Pritlog into your server and it
starts running. No separate installation is required.

The Vulnerability Laboratory Research Team discovered multiple Web Vulnerabilities in Pritlog v0.821 Content Management System.
2012-04-29: Public or Non-Public Disclosure
Multiple persistent input validation vulnerabilities are detected in the Pritlog v0.821 Content Management System. The bugs
allow remote attackers to implement/inject malicious script code on the application side (persistent). Successful exploitation
of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. Exploitation requires
low user inter action. Attackers can inject malicious strings as author name to execute them when an admin is processing to preview, review
or manage the listing of users. The bug is located on application side & the execution is persistent out of the user management web
[+] Manage User Listing - Username & Author
Proof of Concept:
The vulnerability can be exploited by remote attackers with low required user inter action. For demonstration or reproduce ..
<tbody><tr><td><strong>Author: </strong>"><iframe src="a" onload='alert("vl")' <<br=""><br></td>
<input type="text" name="authorEmail" id="authorEmail" value="firstname.lastname@example.org"></td></tr>
The security risk of the persistent input validation vulnerability is estimated as medium.
