NewStart CGSL MAIN 7.02 : openvswitch Multiple Vulnerabilities (NS-SA-2025-0090)

medium Nessus Plugin ID 237992

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has openvswitch packages installed that are affected by multiple vulnerabilities:

- A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. (CVE-2023-5366)

- A flaw was found in Open vSwitch where multiple versions are vulnerable to crafted Geneve packets, which may result in a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled. (CVE-2023-3966)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL openvswitch packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
