2DescriptionCVE.org
A vulnerability was determined in NASA Trick 19.6.0. This issue affects the function JSONVariableServerThread::parse_request of the file trick_source/sim_services/JSONVariableServer/JSONVariableServerThread.cpp of the component TCP Socket Handler. This manipulation causes stack-based buffer overflow. The attack is possible to be carried out remotely. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stack-based buffer overflow in NASA Trick 19.6.0's JSONVariableServer component exposes the simulation framework to remote exploitation via crafted TCP requests, with no patch available and no vendor response to disclosure. The vulnerability resides in JSONVariableServerThread::parse_request, where user-supplied network data is processed through an unbounded sscanf call without bounds checking on a stack-allocated buffer. …

Vulnerability AssessmentAI
| Exploitation | The NASA Trick JSONVariableServer component must be active and its TCP port must be reachable by the attacker - this is an optional subsystem that must be explicitly enabled in the simulation configuration, but is a commonly used feature for external variable monitoring. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) characterizes this as a network-reachable, zero-prerequisite, low-complexity attack - a genuinely dangerous profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the NASA Trick project did not respond to disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
