CVE-2021-34992

Name of the Vulnerable Software and Affected Versions: Orckestra C1 CMS version 6.10

Description: This issue allows remote attackers to execute arbitrary code on affected installations. Authentication is required to exploit this issue. The flaw exists within Composite.dll due to the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this issue to execute code in the context of the service account.

Recommendations: For Orckestra C1 CMS version 6.10, consider restricting access to the Composite.dll module to minimize the risk of exploitation until a patch is available. As a temporary workaround, ensure proper validation of user-supplied data to prevent deserialization of untrusted data.
