The Vulnerability Laboratory Research Team discovered multiple web vulnerabilities in ManageEngines ServiceDesk v8.0 Plus.

2012-11-15:	Public or Non-Public Disclosure




Multiple persistent input validation vulnerabilities are detected in ManageEngines ServiceDesk v8.0 Plus web application.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). 
Two vulnerabilities are located in the my details and request new incidents module of the web front-end with the bound 
vulnerable name, subject and description parameters. Exploitation requires low user inter action & low privileged 
customer web application user account. The secound part of the bugs are located in the New Contract, Access points and 
Create Solution module of the admin/moderator back-end with the bound vulnerable title, asset name, contract name, description 
or support name. Successful exploitation of the vulnerability can lead to session hijacking (customer/manager/admin), persistent 
phishing or stable (persistent) web context manipulation.

Vulnerable Module(s):	Customer/User/Moderator Front-End
			[+] My Details - [Name]
			[+] Requests -> New Incident - [Subject] - [Description] 

Vulnerable Module(s): 	Admin/Moderator Back-End
			[+] Solution -> Create Solution - [Title]
			[+] Assets -> It Assets -> Access points - [Asset name]
			[+] Contract -> New Contract - [Contract Name] - [Description] - [name] - [Support]

Proof of Concept:
The persistent input validation vulnerability can be exploited by remote attackers with low required user inter action 
& low privileged user account. For demonstration or reproduce ...

The vulnerability in the Requester account can be exploited by many different methods. The first attacking vector can be 
launched by creating a request and injecting a malicious code in the subject and description field of the request. When 
the victim views the requests and stops by the mouse courser on the request name. The code gets executed in the small 
pop up window that contains the Subject and Description information of the request. Another way to attack the admin is to 
edit the details of the requester account and inject the malicious code in the field "Name". After that, the attacker 
creates a request. Once the admin views the requests, the code gets executed in the field of the requester name.

The security risk of the persistent input validation vulnerabilities are estimated as medium(+).
