Medium
Details:
========
Multiple persistent input validation vulnerabilities are detected in the DELL PacketTrap MSP v6.6.23938 appliance application.
The bug allows remote attackers to implement/inject own malicious script code on the application side of the software (persistent).
The first persistent vulnerability is located in the add function of the reports (reports manager & scheduled reports|add) module
when processing to request the vulnerable gadget_name, gadget_description, template name and device name parameters.
The vulnerability allows to inject persistent script code as report when processing to add a report or device. The result is the
persistent execution of script code out of the add reports preview software listing. Exploitation requires low user interaction &
a low privileged appliance web application user account.
The secound persistent vulnerability is located in the reports (index listing) module when processing to request the vulnerable
customer name, device name & host name parameter & listing. The vulnerability allows to inject via add function persistent script code.
The result is the persistent execution of script code out of the index reports software listing.
Exploitation of the vulnerability requires low user interaction & a low privilege web application user account.
Successful exploitation of the vulnerability can lead to persistent session hijacking (manager/admin), persistent phishing, persistent
external redirects to malware or scam and (stable) persistent web context manipulation of the affected vulnerable module.

Manually reproduce steps ...
1. Install the PacketTrap MSP RMM Software 6.x and start it up
2. Create an first account and switch to the main menu of the software dashboard
3. Go to the reports section and click on add reports
4. Inject your own script code via add in the vulnerable parameters
5. Click the next step button (down) of the add mask
6. The preview executes the code in the right listing after processing the first step. #reproduce1
7. Now, we reproduce the secound issue. Save the report with the persistent injected own script code
8. Switch (after the save) to the index module of the reports or scheduled reports listing
9. The code will be executed persistent out of the main software reports module when processing to watch the customer name, device name or host name #reproduce2
Risk:
=====
The security risk of the persistent input validation vulnerabilities are estimated as medium(+).
