Opened: Oct 07, 2023

Severity: 3-Major

Symptoms

When trying to match the (XML) content, B64 decode it and then use sideband in an iRule to have the content checked. But this only works for content lengths less than 1024 characters in the relevant XML field.

Impact

Match requests of string lengths more than 1024 bytes will be truncated to 1024 bytes after validation.

Conditions

The content of the XML data which is to be matched is more than 1024 bytes.

Workaround
