An issue was discovered in OpenStack Keystone before 29.0.2. The Keystone federated token rescoping mechanism does not propagate the original token's expiry to the newly issued token. When a federated user rescopes a token via POST /v3/auth/tokens, the handle_scoped_token() function in the mapped authentication plugin returns response data without an expires_at value. The token provider falls back to issuing a token with a fresh default TTL. By rescoping repeatedly before each token expires, a user can maintain access indefinitely, bypassing operator-configured token lifetime policies. This is a variant of CVE-2012-3426. Only deployments using federated identity (SAML2, OpenID Connect) are affected.
A flaw has been found in Alfresco Activiti up to 7.19/8.8.0. Affected by this issue is the function deserialize/createObjectInputStream of the file activiti-core/activiti-engine/src/main/java/org/activiti/engine/impl/variable/SerializableType.java of the component Process Variable Serialization System. This manipulation causes deserialization. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Hyland Alfresco Transformation Service allows unauthenticated attackers to achieve remote code execution through the argument injection vulnerability, which exists in the document processing functionality.
