TitelGovernikus GmbH & Co. KG AusweisApp (Desktop) 2.5.4 Cross Site Scripting
BeschreibungThis vulnerability is submitted by Governikus the vendor and maintainer of the AusweisApp. See: https://www.governikus.de/loesungen/kundenprojekte/ausweisapp/ The Governikus AusweisApp (Desktop) versions 1.10.0 through 2.5.4 contain a cross-site scripting vulnerability (CWE-79) in the processing of the ResultMessage contained in a StartPAOSResponse. An attacker can provide an activation link referencing a malicious eID-Server that returns a crafted ResultMessage. The value is inserted into HTML output without proper escaping of HTML metacharacters, allowing attacker-controlled script code to be executed in the user's browser. The vulnerability is fixed in version 2.5.5 by properly escaping HTML metacharacters before rendering the ResultMessage. CVSS 4.0 Score: 5.1 - https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N
