CWE	https://cwe.mitre.org/data/definitions/420.html

CrushFTP 10 before 10.8.5 and 11 before 11.3.4_23, when the DMZ proxy feature is not used, mishandles AS2 validation and consequently allows remote attackers to obtain admin access via HTTPS, as exploited in the wild in July 2025.

Weakness

The product protects a primary channel, but it does not use the same level of protection for an alternate channel.
