CVE-2020-2260: 
Java vulnerability analysis and mitigation

CVE-2020-2260 is a security vulnerability discovered in Jenkins Perfecto Plugin versions 1.17 and earlier. The vulnerability was disclosed on September 16, 2020, and affects the permission checking mechanism in the plugin's connection test functionality. The affected component is the perfecto Plugin for Jenkins, which is used for integration with Perfecto Mobile testing platform (Jenkins Advisory).

The vulnerability stems from a missing permission check in a method implementing a connection test functionality. The issue has been assigned a Medium severity (CVSS) rating. The vulnerability exists in the authentication mechanism where the plugin fails to properly validate user permissions before allowing connection tests (Jenkins Advisory).

The vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified HTTP URL using attacker-specified username and password credentials. This could potentially lead to unauthorized access and credential exposure (Jenkins Advisory, OSS Security).

The vulnerability can be exploited by attackers who have Overall/Read permission in the Jenkins installation. The attack vector requires the attacker to have basic access to the Jenkins system, but does not require advanced privileges (Jenkins Advisory).

The vulnerability has been fixed in perfecto Plugin version 1.18, which implements proper permission checks requiring Overall/Administer permission to perform connection tests. Users are advised to upgrade to this version to mitigate the vulnerability (Jenkins Advisory).
