Unauthenticated denial of service via heap overflow
Published Jan 10, 2024 · Updated Jun 17, 2025
Heap-based buffer overflow in Bosch Rexroth NEXO-OS through V1500-SP2 allows remote attackers to cause denial of service. Bosch discloses only that a crafted network request reaches the heap-overflow condition; the affected component and faulty memory operation remain undisclosed. No authentication or user interaction is required, but exploitation has high complexity; code execution is a vendor-identified but unconfirmed consequence.
