CVE-2024-3661

HIGHEPSS 90th pctl

7.6

CVSS v3

Description

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.

Is CVE-2024-3661 being actively exploited?

Not that we know of. CVE-2024-3661 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 4.1% is the estimated probability that it will be exploited in the next 30 days. That is higher than 90% of all scored CVEs.

How severe is CVE-2024-3661?

CVE-2024-3661 has a CVSS v3 base score of 7.6, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2024-3661 affect?

Published advisories record a fix for NetworkManager (Red Hat / RHEL), NetworkManager (Rocky), NetworkManager-adsl (Red Hat / RHEL), NetworkManager-adsl (Rocky), and 53 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
