CVE-2024-28787 is a critical-severity trusting HTTP permission methods on the server side vulnerability in Security Verify Access Container from IBM, with a CVSS 3.1 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Security Verify Access Container versions: 10.0.0 through 10.0.7. 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 Security Verify Access Container you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on exchange.xforce.ibmcloud.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 Security Verify Access 10.0.0 through 10.0.7 and IBM Application Gateway 20.01 through 24.03 could allow a remote attacker to obtain highly sensitive private information or cause a denial of service using a specially crafted HTTP request. IBM X-Force ID: 286584.

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.
