normalize_uri() should be used when you're joining URIs. Because if you're merging URIs after it's normalized, you could get double slashes again.

|
|
This module exploits a vulnerability found in PhpTax, an income tax report
|
|
generator. When generating a PDF, the icondrawpng() function in drawimage.php
|
|
does not properly handle the pfilez parameter, which will be used in a exec()
|
|
statement, and then results in arbitrary remote code execution under the context
|
|
of the web server. Please note: authentication is not required to exploit this
|
|
vulnerability.
