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.

Abstract:
=========
Vulnerability-Lab Team  discovered multiple web vulnerabilities on LDAPs 
Account Manager Pro v3.6.


Report-Timeline:
================
2012-02-22:     Public or Non-Public Disclosure


Status:
========
Published


Affected Products:
==================
Open Source
Product: LDAP Account Manager Pro (lamp) v3.6


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium


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

                                        ../2.png

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

                                        ../4.png


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

Risk:
=====
The security risk of the persistent web vulnerabilities are estimated as 
medium(+).
