Vulnerability Spotlight: Multiple vulnerabilities in Atlassian Jira

Summary: Ben Taylor of Cisco ASIG discovered multiple vulnerabilities in Atlassian Jira, from versions 7.6.4 to 8.1.0, including a persistent XSS in WikiRenderer triggered by a crafted comment or worklog entry and CSRF flaws in the login form that require no CSRF token. Additional issues let anonymous users distinguish valid issue keys, attachment names and usernames via API endpoints, let authenticated users view worklog details and Tempo plugin issue summaries they lack permission to see, and let an attacker controlling a different subdomain inject cookies and submit CSRF attacks as a logged-in user.
What's compelling: These flaws let anonymous or low-privilege users map out valid issue keys, attachment names and usernames, and let an attacker with a lookalike subdomain act as a logged-in user - so the task and document data your teams keep in Jira may be enumerable by people who were never granted access to it.
