Deeper analysis
A reflected cross-site scripting vulnerability exists in the web interface of Siemens SINEMA Remote Connect Server in all versions prior to V3.1. The flaw stems from an error message popup window that fails to sanitize input, allowing JavaScript injection as classified under CWE-79. The issue carries a CVSS 3.1 base score of 6.1 with network attack vector, low complexity, no required privileges, required user interaction, and changed scope yielding limited confidentiality and integrity impact.
An unauthenticated remote attacker can exploit the weakness by crafting a malicious link or request that triggers the vulnerable popup when a user views it, enabling execution of arbitrary script in the context of the affected application. Successful exploitation could let the attacker read or manipulate limited data accessible to the victim user within the SINEMA interface.
Siemens has published security advisory SSA-484086, available in both HTML and PDF formats on its cert portal, which addresses the reflected XSS issue in SINEMA Remote Connect Server. The EPSS score for this CVE has remained flat at 0.0705 with no material increase observed since disclosure.
