CVE-2017-8031: Cloudfoundry Cf-Release

Medium severity, CVSS 5.3. EPSS: 1.1% chance of exploitation in the next 30 days.

An issue was discovered in Cloud Foundry Foundation cf-release (all versions prior to v279) and UAA (30.x versions prior to 30.6, 45.x versions prior to 45.4, 52.x versions prior to 52.1). In some cases, the UAA allows an authenticated user for a particular client to revoke client tokens for other users on the same client. This occurs only if the client is using opaque tokens or JWT tokens validated using the check_token endpoint. A malicious actor could cause denial of service.

Affected products

• Cloudfoundry Cf-Release: up to and including 278
• Cloudfoundry Uaa-Release: from 30, before 30.6 (fixed in 30.6); from 45, before 45.4 (fixed in 45.4); version 52 only
