In Python before 3.9.5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses.
Release : 10.6
Messaging Gateway for Service Providers (SMG-SP) is not affected by this vulnerability.
The SMG-SP product does not use python for any of it's operations. Neither does SMG-SP rely in any way on the "system python" of the servers it is installed on.
