Description

Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.
A flaw was found in golang. Extraneous zero characters at the beginning of an IP address octet are not properly considered which could allow an attacker to bypass IP-based access controls. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
