CVE-2024-27323

Estado: AnalizadaAlta (7.5)—

PDF-XChange Editor Updater Improper Certificate Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PDF-XChange Editor. User interaction is not required to exploit this vulnerability.

The specific flaw exists within the update functionality. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-22224.
