Glassfish: Improper Control of Dynamically-Managed Code Resources
CVE-2023-5763 is a critical-severity improper control of dynamically-managed code resources vulnerability in Glassfish from Eclipse Foundation, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Glassfish versions: 6.0.0 through 6.2.5; 5.0 through 5.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.81% chance of exploitation within 30 days, higher than 58% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Glassfish you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on gitlab.eclipse.org 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.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Eclipse Foundation | Glassfish | 6.0.0 through 6.2.5; 5.0 through 5.1 | Not stated |

Official description
In Eclipse Glassfish 5 or 6, running with old versions of JDK (lower than 6u211, or < 7u201, or < 8u191), allows remote attackers to load malicious code on the server via access to insecure ORB listeners.

The underlying weakness: Improper Control of Dynamically-Managed Code Resources
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
How developers prevent this class of flaw
- For any externally-influenced input, check the input against an allowlist of acceptable values.
- Refactor the code so that it does not need to be dynamically managed.
