CVE-2023-20136
Status: ModifiedMedium (6.5)—
A vulnerability in the OpenAPI of Cisco Secure Workload could allow an authenticated, remote attacker with the privileges of a read-only user to execute operations that should require Administrator privileges. The attacker would need valid user credentials.
This vulnerability is due to improper role-based access control (RBAC) of certain OpenAPI operations. An attacker could exploit this vulnerability by issuing a crafted OpenAPI function call with valid credentials. A successful exploit could allow the attacker to execute OpenAPI operations that are reserved for the Administrator user, including the creation and deletion of user labels.
