CVE-2023-4551Network attack vector

Authenticated command execution via Scheduler task creation

Published Jan 29, 2024 · Updated Aug 2, 2024

OS command injection in OpenText AppBuilder 21.2 through releases before 23.2 allows remote authenticated users to execute arbitrary commands. OpenText identifies the Scheduler task-creation path but has not published the affected field, command construction, or precise validation failure. Exploitation requires an authenticated account with high privileges and runs commands with the permissions of the AppBuilder process.
