What is CVE-2024-4032?
CVE-2024-4032 is a high-severity vulnerability in CPython, published on 17 Jun 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The “ipaddress” module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as “globally reachable” or “private”. This affected the is_private and is_global properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network classes, where values wouldn’t be returned in accordance with the latest information from the IANA Special-Purpose Address Registries.
CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended behavior.
Weakness: CWE-697
