Jetty: Uncontrolled Resource Consumption
CVE-2024-9823 is a high-severity uncontrolled resource consumption vulnerability in Jetty from Eclipse Foundation, 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 versions 9.4.54, 10.0.18, 11.0.18 as the first without the flaw, so updating Jetty to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.94% chance of exploitation within 30 days, higher than 61% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Jetty to 9.4.54 or 10.0.18 or 11.0.18 or 12.0.3, whichever matches your release line, or a later version.
- Update Jetty to 12.0.3 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource.
How developers prevent this class of flaw
- Ensure that protocols have specific limits of scale placed on them.
- Ensure that all failures in resource allocation place the system into a safe posture.
