CVE-2023-42358Public exploitNetwork attack vector

Service interruption via crafted API request

Published Jan 3, 2024 · Updated Jun 18, 2025

Denial of service in O-RAN Software Community ric-plt-e2mgr G-Release allows remote attackers to interrupt E2Manager via a crafted API request. The public record identifies the E2Manager API as the request-processing locus but does not disclose which handler or operation mishandles the crafted input. Network access to the API is sufficient under CISA's unauthenticated assessment, and the documented consequence is limited to service availability loss.
