CVE-2023-37959 is a missing permission check vulnerability discovered in Jenkins Sumologic Publisher Plugin versions 2.2.1 and earlier. The vulnerability was disclosed on July 12, 2023, as part of a larger Jenkins security advisory. The vulnerability affects the form validation method implementation in the Sumologic Publisher Plugin (Jenkins Advisory, GitHub Lab).

The vulnerability stems from a missing permission check in a method implementing form validation. The issue resides in the com.sumologic.jenkins.jenkinssumologicplugin.PluginDescriptorImpl#doTestURL method. The vulnerability has been assigned a Medium severity CVSS rating. When combined with CVE-2023-37958 (CSRF vulnerability), it creates a security weakness that could be exploited through form validation methods that don't require POST requests (GitHub Lab).

The vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified URL. This could potentially lead to server-side request forgery (SSRF) attacks, enabling attackers to make unauthorized connections to arbitrary hosts (Jenkins Advisory, GitHub Lab).

As of the advisory publication date, there is no fix available for this vulnerability in the Sumologic Publisher Plugin. Users are advised to monitor for updates and implement additional security controls to restrict access to the affected functionality (Jenkins Advisory).

The vulnerability was discovered and reported by Alvaro Muñoz (@pwntester) from GitHub Security Lab. It was part of a larger security advisory that included multiple vulnerabilities in various Jenkins plugins (Jenkins Advisory).
