CVSS v3.1
Official Description
Integer overflow in inc/server.hpp in libnet6 (aka net6) before 1.3.14 might allow remote attackers to hijack connections and gain privileges as other users by making a large number of connections until the overflow occurs and an ID of another user is provided.
Technical Analysis
CVE-2011-4093 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
