"A vulnerability has been identified in Desigo PXC4 (All versions <
V02.20.142.10-10884), Desigo PXC5 (All versions <
V02.20.142.10-10884). The addCell JavaScript function fails to
properly sanitize user-controllable input before including it into the
generated XML body of the XLS report document, such that it is
possible to inject arbitrary content (e.g., XML tags) into the
generated file. An attacker with restricted privileges, by poisoning
any of the content used to generate XLS reports, could be able to
leverage the application to deliver malicious files against higher-
privileged users and obtain Remote Code Execution (RCE) against the
administrator's workstation.
