[Security advisory for CVE-2022-35403] Unauthenticated local file disclosure vulnerability in ServiceDesk Plus

Dear customers,

 

This is a security advisory for CVE-2022-35403 regarding the unauthenticated local file disclosure vulnerability in inline image handling in ServiceDesk Plus, which has been identified and rectified. This affects on-premises users of ServiceDesk Plus (all editions) running version 13007 and below.

This issue was reported by our internal security team on our bug bounty portal.

 

Severity: High

 

Impact
This vulnerability allows adversaries to download local files from the server on which ServiceDesk Plus is installed by sending an email to the email address configured in the application with a crafted image URL pointing to the specific file. If the file is present in that location, it gets added as an attachment in the ticket conversation when a technician responds to or when a notification is triggered for the ticket.

 

What led to the vulnerability?
The image's URL was not being processed properly when a technician responded to it or when a notification was triggered for the ticket.


Who is affected?

This vulnerability affects on-premises ServiceDesk Plus customers of all editions using versions 13007 and below.

 

How have we fixed it?

We have added additional checks to process the inline image to avoid the local file disclosure vulnerability.
