descriptionAccording to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is prior to prior to 8.4.0. It is, therefore, affected by multiple vulnerabilities: - An authorization bypass vulnerability exists in the /rest/issueNav/1/issueTable resource as well as the /rest/api/latest/groupuserpicker resource. An unauthenticated, remote attacker can exploit this, to enumerate usernames due to an incorrect authorization check. (CVE-2019-8449) - A server-side request forgery (SSRF) vulnerability exists in the /plugins/servlet/gadgets/makeRequest resource due to a logic bug in the JiraWhitelist class. A remote attacker can exploit this to access the content of internal network resources via a Server Side Request Forgery (SSRF) vulnerability. (CVE-2019-8451) - An authentication bypass vulnerability exists in the /rest/api/1.0/render rest resource. An unauthenticated, remote attacker can exploit this, to determine if an attachment with a specific name exists and if an issue key is valid due to a missing permissions check. (CVE-2019-14995) - An information disclosure vulnerability exists in the AccessLogFilter class due to a caching vulnerability. A remote anonymous attackers can exploit this to access details about other users, including their username, when Jira is configured with a reverse Proxy and or a load balancer with caching or a CDN. (CVE-2019-14997) - A cross-site request forgery (XSRF) vulnerability exists in Webwork action Cross-Site Request Forgery (CSRF) protection. A remote attacker can exploit this by bypassing its protection by
