Introduction:  
=============  
LDAP Account Manager Pro is an extended version of LAM which focuses on enterprise usage. It helps you to lower your   
administration costs by providing enhanced tools for your users and deskside support staff.  
Features LDAP Account Manager (LAM) is a webfrontend for managing entries (e.g. users, groups, DHCP settings) stored   
in an LDAP directory. LAM was designed to make LDAP management as easy as possible for the user. It abstracts from the   
technical details of LDAP and allows persons without technical background to manage LDAP entries. If needed, power   
users may still directly edit LDAP entries via the integrated LDAP browser.

Details:  
========  
1.1  
Multiple persistant input validation vulnerabilities are detected on LDAPs Account Manager Pro v3.6.  
The bug allows remote attacker to implement malicious script code on the application side (persistent).  
Successful exploitation of the vulnerability allows an attacker to manipulate modules/context (persistent) & can   
lead to session hijacking (user/mod/admin).  
  
Vulnerable Module(s):  
[+] User Listing & List Input/Output  
[+] Export

1.2  
Multiple client-side Cross Site Scripting vulnerabilities are detected on LDAPs Account Manager Pro v3.6.  
The bug allows remote attacker hijack customer/admin sessions with medium required user inter action.   
Successful exploitation leads to session hijacking or client side module manipulation attacks and the result   
is account steal.  
  
Vulnerable Module(s):  
[+] &attr=  
[+] Filter- Search & Listing

Proof of Concept:  
=================  
The vulnerabilities can be exploited by remote attacker with low & high required user inter action.
