Low risk11th percentile - higher than 11% of all known CVEs
Summary
Jenkins SAML Single Sign On (SSO) Plugin version 2.0.2 and earlier does not perform hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata. This could be exploited using a man-in-the-middle attack to intercept these connections.
Risk Assessment
The lack of hostname validation poses a risk of credential interception by an attacker, potentially leading to unauthorized access to the system.
Recommendation
It is recommended to update the plugin to the latest version that includes fixes for hostname validation and to review security configurations.
