What’s new in ISPConfig

This release contains an important security fix for an insufficient validation of the PHP version selector.

Scope of the issue: an attacker would require a valid ISPConfig login with access to the web module. The issue affects the ISPConfig interface only, on a multiserver system, only the interface server(s) have to be patched.

Thank you to Timo Boldt for reporting this issue!

The fix can be applied by updating to ISPConfig or by using the ISPConfig patch tool.
