## Vulnerability ##  
#  
# AkoBook is a Guestbook component for Mambo. A vulnerability in AkoBook  
# 3.42 and earlier versions can be exploited by malicious people to conduct  
# cross-site scripting attacks.  
#  
# Input passed to the "gbmail" and "gbpage" parameters in the signing page  
# (generally index.php?option=com_akobook&func=sign) is not properly santised.  
# This can be exploited to inject script code into the page, and as a result  
# conduct a persistente XSS attack.  
#  
# Some characters as "<" and ">" are not allowed but simple quotes can still  
# be used. The following code in one of the vulnerable inputs would result in  
# a XSS:  
# Injection: wawa' onload=javascript:alert(/XSS/) a='  
#  
# After the script is sent, it should appear in the guestbook source code  
# like this, exploiting the XSS flaw:  
#  
# <a href='http://wawa\' onload=javascript:alert(/XSS/) a=\''>  
# <img src='homepage.gif' alt='http://wawa\' onload=javascript:alert(/XSS/) a=\''></a>  
#  
#  
## How to fix ##  
#  
# Santise quotes properly in all the form inputs.
