CVE-2021-44029

CRITICAL

9.8

CVSS v3

NVD

Description

An issue was discovered in Quest KACE Desktop Authority before 11.2. This vulnerability allows attackers to execute remote code through a deserialization exploitation in the RadAsyncUpload function of ASP.NET AJAX. An attacker can leverage this vulnerability when the encryption keys are known (due to the presence of CVE-2017-11317, CVE-2017-11357, or other means). A default setting for the type whitelisting feature in more current versions of ASP.NET AJAX prevents exploitation.
