CVE-2023-24437: 
Java vulnerability analysis and mitigation

JIRA Pipeline Steps Plugin version 2.0.165.v8846cf59f3db and earlier contains a cross-site request forgery (CSRF) vulnerability and missing permission checks (CVE-2023-24437, CVE-2023-24438). The vulnerability was disclosed on January 24, 2023, affecting the Jenkins JIRA Pipeline Steps Plugin (Jenkins Advisory).

The vulnerability stems from two main issues: First, the plugin does not perform permission checks in methods implementing form validation, which allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs. Second, the form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. The severity is rated as Medium according to the CVSS scoring system (Jenkins Advisory).

The vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through other methods, potentially leading to the capture of credentials stored in Jenkins (Jenkins Advisory).

The vulnerability can be exploited by attackers who have Overall/Read permission in the Jenkins environment. The exploitation involves taking advantage of both the missing permission checks and the CSRF vulnerability to potentially capture credentials (Jenkins Advisory).

As of the publication of the security advisory, no fixes are available for this vulnerability in the JIRA Pipeline Steps Plugin. Users should monitor for updates and implement general security best practices to minimize risk (Jenkins Advisory).
