Hi
We are currenting using 7.19.5 version
Could you please let me know to mitigate CVE-2023-22508 this issue which version we need to migrate.
Please suggested LTS or any version to overcome the vulnerability issues.
A fix for this issue is available in Confluence Server and Data Center 7.13.20.
Upgrade now or check out the Release Notes to see what other issues are resolved.
Joe Red: it has been fixed in the 7.19.x at 7.19.8 so yes 7.19.11 is fixed and is an LTS (which 8.4 is not)
Hi Joe,
regarding https://confluence.atlassian.com/confkb/how-to-disable-the-jmx-network-port-for-cve-2023-22508-1267761550.html, your assumption is correct:
If you're running an affected version of Confluence, you're only vulnerable if you currently have a TCP port enabled for JMX, as outlined in Live Monitoring Using the JMX Interface. TCP ports for JMX are not configured by default in Confluence.
Joe Red: 7.17.4 is old and unsupported so prone to other vulnerabilities. I would recommend you to migrate to an LTS such as 7.19.11
VamsiKBC: to get the latest 7.19.x, which is currently 7.19.12
