CVE-2024-22348 is a high-severity permissive cross-domain security policy with untrusted domains vulnerability in UrbanCode Velocity 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 UrbanCode Velocity versions: 4.0.0 through 4.0.25. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.37% 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 UrbanCode Velocity 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.

Official description
IBM DevOps Velocity 5.0.0 and IBM UrbanCode Velocity 4.0.0 through 4.0. 25 uses Cross-Origin Resource Sharing (CORS) which could allow an attacker to carry out privileged actions and retrieve sensitive information as the domain name is not being limited to only trusted domains.

The underlying weakness: Permissive Cross-domain Security Policy with Untrusted Domains
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.
How developers prevent this class of flaw
- Define a restrictive Content Security Policy or cross-domain policy file.
- Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.
- For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
