A reflected cross-site scripting (XSS) vulnerability in Hyland Alfresco Platform 23.2.1-r96 allows attackers to execute arbitrary code in the context of a user's browser via injecting a crafted payload into the parameter htmlid.

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.

An issue was discovered in Hyland org.alfresco:alfresco-content-services through 6.2.2.18 and org.alfresco:alfresco-transform-services through 1.3. A crafted HTML file, once uploaded, could trigger an unexpected request by the transformation engine. The response to the request is not available to the attacker, i.e., this is blind SSRF.

An issue was discovered in Hyland org.alfresco:alfresco-content-services through 7.0.1.2. Script Action execution allows executing scripts uploaded outside of the Data Dictionary. This could allow a logged-in attacker to execute arbitrary code inside a sandboxed environment.
