File Upload Vulnerability in Desktop Central & Mobile Device Manager Plus

ManageEngine have released an important security update for Desktop Central and Mobile Device Manager Plus which addresses a file upload vulnerability. Read on for more details.

Issue: Arbitrary File Upload Vulnerability

What is the issue?

Desktop Central and Mobile Device Manager Plus allow users to upload Windows app dependency files in a ZIP format on to the product server.

Older builds had a vulnerability that allowed malicious users to upload a specially crafted ZIP file without proper validation, allowing them to potentially save files in any location

Who is affected?

Users running any of the below versions are at risk of exploitation:

How severe is this vulnerability?

The CVSS categorisation of the vulnerability is High.

To exploit this vulnerability, the user must authenticate themselves
by logging in to the product console. They also need permissions
to add apps to the App Repository. These two prerequisites reduce
the chance of someone exploiting this vulnerability.

What steps did the team take to mitigate this vulnerability?

The fix for this vulnerability was released in build number 100482
for Desktop Central and Desktop Central MSP, and build number 92789 for Mobile Device Manager Plus and Mobile Device Manager
Plus MSP.

The following steps were taken:

1. All the uploaded ZIP files were validated, and any files with
   path traversal capabilities were removed.
2. Only the required files were extracted instead of the entire
   ZIP file. Before extraction, all file extensions and content
   were verified, and only files required for the particular function
   were extracted.
