Product & Service 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.

Discovery Status:
=================
Published


Affected Product(s):
====================
Open Source
Product: LDAP Account Manager Pro (lamp) 3.6


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


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


Technical Details & Description:
================================
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).
