CVE-2024-6426

Local resource access via API-value manipulation

Published Jul 3, 2024 · Updated Aug 1, 2024

Information exposure in MESbook 20221021.03 allows local users with application privileges to access unauthorized resources via API-value changes. The application trusts a user-controlled API value when selecting resources without enforcing the intended resource boundary. A low-privilege local application context is required, and the public advisory does not identify the exposed resource types.
