Buffer Overflow in NASA openVSP via Geometry Name Field

Publication date: 2026-05-25

Last updated on: 2026-05-25

Assigner: VulnCheck

Description

NASA openVSP 3.16.1 contains a buffer overflow vulnerability that allows local attackers to crash the application by supplying an excessively long string in the geometry name field. Attackers can trigger a denial of service by pasting a 5000-byte payload into the name input field within the Geom browser pod addition interface.

Attack-Flow Graph

Executive Summary

This vulnerability exists in NASA openVSP version 3.16.1 and is a buffer overflow issue. It occurs when a local attacker inputs an excessively long string into the geometry name field of the application. Specifically, by pasting a 5000-byte payload into the name input field within the Geom browser pod addition interface, the attacker can cause the application to crash.

Impact Analysis

The primary impact of this vulnerability is a denial of service (DoS). An attacker can cause the NASA openVSP application to crash by exploiting the buffer overflow, which disrupts normal operation and availability of the software.
