Deeper analysis
CVE-2023-29375 affects Progress Sitefinity versions 13.3 before 13.3.7647, 14.0 before 14.0.7736, 14.1 before 14.1.7826, 14.2 before 14.2.7930, and 14.3 before 14.3.8025. The flaw is an unrestricted file upload condition (CWE-434) exposed through the SharePoint connector, rated at CVSS 9.8 with network attack vector, low complexity, and no authentication or user interaction required.
An unauthenticated remote attacker can upload arbitrary files via the connector, enabling execution of malicious content that results in full confidentiality, integrity, and availability impact on the affected Sitefinity instance. The connector's handling of SharePoint-sourced uploads bypasses normal file-type or destination restrictions present in other upload paths.
The referenced Progress security advisory details the affected releases and directs administrators to apply the corresponding fixes (13.3.7647, 14.0.7736, 14.1.7826, 14.2.7930, or 14.3.8025) that remediate the SharePoint connector upload logic.
