Name of the Vulnerable Software and Affected Versions ArcGIS Server version 11.5

Description An input validation weakness exists in the login redirection workflow. An authenticated attacker can send a specially crafted request to redirect the browser to an unintended and untrusted site, which may lead to a limited confidentiality impact depending on user interaction. This issue is confined to the client-side navigation logic during authentication and does not allow for server-side compromise or cross-component impact.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
