CVE-2023-45703Network attack vector

Authenticated service interruption via malformed archive upload

Published Dec 20, 2023 · Updated Aug 2, 2024

Denial of service in HCL DevOps Deploy 7.0 through 7.3.2.2 allows remote authenticated users to exhaust resources via archive upload. The archive-upload path inadequately validates a submitted archive before processing it, allowing crafted content to consume excessive resources; HCL has not disclosed the exact parser or validation error. A low-privileged authenticated account and a crafted archive are required, and successful exploitation interrupts service without reported data disclosure or modification.
