CVE-2023-46156

Affected devices improperly handle specially crafted packets sent to port 102/tcp.

HIGH 7.5EPSS 1.24%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Affected devices improperly handle specially crafted packets sent to port 102/tcp. This could allow an attacker to create a denial of service condition. A restart is needed to restore normal operations.
