Short explanation
NASA JPL ION-DTN versions 3.6.2 through 4.2.0 contain a heap-based buffer overflow vulnerability in the Network Management daemon (nm_mgr) string-formatting logic.
This flaw can be triggered remotely or locally to cause a denial of service, halting telemetry collection and operator visibility.
What should be done?
- Follow vendor advisories
- Update affected versions
Chain of evidence and sources
NASA JPL ION-DTN 3.6.2 ve 4.2.0 sürümleri dahil olmak üzere aradaki sürümler heap tabanlı tampon taşması açığı içermektedir.
Saldırganlar UDP CLA/AMP yoluyla büyük AMP raporları ileterek veya arayüz oluşturma yoluyla bu kusuru tetikleyebilir.
Show the technical text from the sources
NASA JPL ION-DTN 3.6.2 through 4.2.0 contains a heap-based buffer overflow in the Network Management daemon (nm_mgr) string-formatting logic that allows a malicious or misconfigured agent to trigger an out-of-bounds write by sending deeply nested AMP payloads that exceed fixed-size buffer allocations through unbounded strcat operations. Attackers can transmit oversized AMP reports, tables, or macros over the UDP CLA/AMP path or trigger the flaw locally via interactive UI rendering to crash nm_mgr and cause a denial of service halting telemetry collection and operator visibility.
