CVE-2018-20857

Name of the Vulnerable Software and Affected Versions: Zendesk Samlr versions prior to 2.6.2

Description: The issue allows an XML nodes comment attack, where an attacker can manipulate the name id node by including a comment (<!---->) followed by the attacker's domain name, potentially allowing for malicious activities. This can be initiated by setting up a name id node with an email address, such as user@example.com, followed by the comment and the attacker's domain.

Recommendations: For versions prior to 2.6.2, update to version 2.6.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of XML nodes comments in the name id node to minimize the risk of exploitation.
