Summary

Autodesk® InfraWorks® has been affected by multiple vulnerabilities detailed below. Exploitation of these vulnerabilities may lead to remote code execution and/or denial-of-service to the software and user devices. Hotfixes are available in the Autodesk Desktop App or the Accounts Portal to help resolve these vulnerabilities.

Description

The details of the vulnerabilities are as follows:

  1. CVE-2021-3711 - A malicious actor who is able present SM2 content for decryption to an application could cause targeted data to overflow the buffer by up to a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing application behavior or causing the application to crash. The location of the buffer is application-dependent but is typically heap allocated. Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k).

Recommendations

Autodesk highly recommends that customers of the affected products obtain and apply the latest Hotfixes via the Autodesk Desktop App or the Accounts Portal. Customers who are using impacted product versions should then reinstall the software to apply the latest Hotfixes.

 

Customers of Infraworks version 2020: when applying the hotfix for 2020.2, the update will launch the product after installation for the very first time and users may encounter a window asking for git credentials. We suggest closing the git credentials window. Note that this only occurs upon the first launch.

 

Customers using previous versions that no longer qualify for full support should plan to upgrade to a supported version as soon as possible to avoid downtime and potential security vulnerabilities. Visit the Autodesk Knowledge Network for more information about previous version support.
