CVE-2023-22515 Atlassian Confluence Data Center and Server Broken Access Control Vulnerability secondary_impact T1078 Valid Accounts
Comments
This vulnerability is exploited through improper input validation in Atlassian Confluence, allowing remote attackers to translate arbitrary HTTP parameters into getter/setter sequences via the XWorks2 middleware. This vulnerability enables the creation of unauthorized Confluence administrator accounts and the upload of malicious plugins, granting attackers the ability to modify Java objects at runtime and execute arbitrary code. A nation-state actor known as Storm-0062 has been attributed to exploiting this vulnerability in the wild.
