Introduction:

Microsoft Exchange Server is, by a distance, the most popular communication, collaboration and email messaging application today!
MS Exchange serves as the hub of all email communications in most corporate environments that use the Microsoft Active Directory
technology. It becomes a necessity to have an Exchange reporting tool that will equip and Exchange Administrator with precise,
granular, comprehensive and actionable data on all aspects of the MS Exchange Server. Exchange Reporter Plus

Status:

Published

Exploitation-Technique:

Remote

Severity:

Medium

Details:

1.1
A persistent input validation vulnerability is detected in Exchange Reporter Plus v4.1, a web-based analysis and reporting solution.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). The persistent vulnerability
is located in Schedule New Report module with the bound vulnerable Schedule Name Schedule Description parameters. Successful exploitation of
the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. Exploitation requires low user
inter action & privileged user account.

Vulnerable Module(s):
[+] Schedule New Report

Vulnerable Parameter(s):
[+] Schedule Name
[+] Schedule Description

1.2
Multiple non persistent cross site scripting vulnerability is detected in Exchange Reporter Plus v4.1, a web-based analysis and reporting solution.
The vulnerability allows remote attackers to hijack website customer, moderator or admin sessions with medium or high required user inter action
or local low privileged user account. The first vulnerability is located in ReportsIndex.do with the bound vulnerable reportCategoryID parameter.
The second vulnerability is located in search box for reports. Successful exploitation can result in account steal, client site phishing & client-side
content request manipulation.

Vulnerable Module(s):
[+] Reports

Vulnerable File(s):
[+] ReportsIndex.do

Vulnerable Parameter(s):
[+] reportCategoryID
[+] search report

Proof of Concept:

1.1
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 attacker schedules a new report and inserts in schedule name and schedule description his own malicious javascript or html code.
Then inject the malicious script code i.e., <iframe src=www.vuln-lab.com onload=alert("VL")/>
When the user browses the alarms page in the control panel the persistent injected script code will be
executed out of the web application context.

1.2
PoC:
http://exchangereporterplus.127.0.0.1:8080/exchange/ReportsIndex.do
?selectedTab=reports&reportCategoryID=3+>"<iframe src=http://www.vuln-lab.com onload=alert("VL")></iframe>

The attacker can go to reports and insert own malicious script code inside of the search report box to exploit the service application.

Risk:

1.1
The security risk of the persistent input validation vulnerability is estimated as medium(+).

1.2
The security risk of the client side cross site vulnerabilities are estimated as low(+).
