An issue was discovered in Hyland Alfresco Community Edition through 7.2.0. By inserting malicious content in the folder.get.html.ftl file, an attacker may perform SSTI (Server-Side Template Injection) attacks, which can leverage FreeMarker exposed objects to bypass restrictions and achieve RCE (Remote Code Execution). NOTE: this issue exists because of an incomplete fix for CVE-2020-12873.
Weakness
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
