GS-4210-24PL4C hardware 2.0: Uncontrolled Resource Consumption
CVE-2024-8454 is a high-severity uncontrolled resource consumption vulnerability in GS-4210-24PL4C hardware 2.0 from PLANET Technology, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 2.305b240719 as the first without the flaw, so updating GS-4210-24PL4C hardware 2.0 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.61% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update GS-4210-24PL4C hardware 2.0 to 2.305b240719 or a later version.
- Update GS-4210-24P2S hardware 3.0 to 3.305b240802 or a later version.
- Update gs-4210-24pl4c_hardware_3.0 to 3.305b240802 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
