CVE-2024-56339 is a high-severity trusting HTTP permission methods on the server side vulnerability in WebSphere Application Server from IBM, 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. Affected WebSphere Application Server versions: 9.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.5% 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
- Check which version of WebSphere Application Server you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on ibm.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: Trusting HTTP Permission Methods on the Server Side
The server contains a protection mechanism that assumes that any URI that is accessed using HTTP GET will not cause a state change to the associated resource.
How developers prevent this class of flaw
- The access control needs to be properly enforced in the application. No assumptions should be made that only HTTP DELETE, PUT, POST, and other methods have the power to alter the representation of the resource being accessed in the request.
- Configure ACLs on the server side to ensure that proper level of access control is defined for each accessible resource representation.
