[Security advisory] Vulnerability in ServiceDesk Plus versions 11005 and above

Hi there,

 

This is a security advisory regarding a possible authentication bypass vulnerability in a few REST API URLs in ServiceDesk Plus, which has been identified and rectified. On-premises users of ServiceDesk Plus (all editions) with version 11005 and above might be affected by this vulnerability and are advised to update to the latest version (11302) immediately.

 

Severity: Critical

 

Impact:

This vulnerability allows an attacker to gain unauthorized access to the application's data through its API support. This would allow the attacker to gain unauthorized access to user data or aid subsequent attacks.

 

To do so, an attacker has to manipulate any vulnerable API URL path from the requests or assets module with a proper character set replacement. This URL can bypass the authentication process and fetch the required data for the attacker.

 

What led to the vulnerability?

The security framework layer used in ServiceDesk Plus had an improper URL validation  process that led to the vulnerability.

 

Who is affected?

This vulnerability affects ServiceDesk Plus (on-premises) customers of all editions using versions 11005 and above.

 

 

How have we fixed it?

The vulnerability has been addressed by fixing the improper URL validation process in the security framework layer in the latest version of ServiceDesk Plus.

Important note: As always, make a copy of the entire ServiceDesk Plus installation folder before applying the upgrade, and keep the copy in a separate location. If anything goes wrong during the upgrade, you'll have this copy as a backup, which will keep all your settings intact. If you're using an MS SQL server as a back-end database, back up the ServiceDesk Plus database before upgrading. Once the upgrade is successfully completed, remember to delete the backup.
