SourceCVE-2024-21674

Atlassian Confluence, a popular enterprise collaboration and documentation tool, was found to have a serious remote code execution (RCE) vulnerability. Attackers could exploit this vulnerability without any authentication, allowing them to run malicious code on vulnerable Confluence servers.

The vulnerability received a CVSS score of 8.6 out of 10 due to its ability to compromise the confidentiality of systems. While it did not impact integrity or availability, an attacker could use it to install malware, steal data, or access other systems on the internal network that the Confluence server has access to.

By crafting specially crafted HTTP requests, an attacker could exploit the vulnerability and execute arbitrary commands with the privileges of the Confluence application. This could allow them to install web shells, cryptominers, or other harmful payloads.

Atlassian has released patches for all supported versions of Confluence to address this issue. Administrators should upgrade immediately to the latest version or one of the specified fixed versions. It is also recommended to verify your installation is fully up to date and to monitor logs for any unusual activity. Taking prompt action helps protect sensitive information and prevent disruption from exploits.
