Published Jan 10, 2024 · Updated Apr 17, 2025

Stack-based buffer overflow in Bosch Rexroth NEXO-OS 1000-Release through 1500-SP2 allows remote attackers to interrupt service or execute code. Bosch identifies a crafted network request as the trigger but has not disclosed the affected service, parser, field, or erroneous memory operation. No authentication or user interaction is required; service interruption is confirmed, while code execution is reported as a possible outcome under undisclosed high-complexity conditions.
