CVE-2024-24993Network attack vector

SYSTEM code execution via missing object locking

Published Apr 19, 2024 · Updated Aug 1, 2024

Race condition in the web component of Ivanti Avalanche before 6.4.3 allows remote authenticated users to execute commands as SYSTEM. The InstallPackageThread class performs operations on a shared object without proper locking, creating a time-of-check-to-time-of-use window. Exploitation requires authenticated network access and grants command execution with the service's SYSTEM privileges.
