PX4 Autopilot through 1.17.0 contains a stack buffer over-read vulnerability in the netman system command that fails to validate interface name length. Attackers can supply interface names of 74 bytes or more via the -i option to read beyond buffer boundaries, leaking stack memory to console output or writing it into persistent network configuration files.
AnalysisAI
Stack buffer over-read in PX4 Autopilot through v1.17.0 exposes stack memory via the netman system command's interface name handling. Supplying an interface name of 74 bytes or more via the -i option bypasses missing length validation, causing reads beyond allocated buffer boundaries; the over-read data leaks to console output and may also be written into persistent network configuration files, risking both information disclosure and config corruption across reboots. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to execute the netman system command on the PX4 Autopilot with an attacker-controlled -i argument of 74 bytes or more. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L) scores 5.3 (Medium), correctly reflecting adjacent-network reach, no authentication barrier, and modest confidentiality and availability impacts. … 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 | The upstream fix is available via GitHub PR #28483 (https://github.com/PX4/PX4-Autopilot/pull/28483) and commit fec216e9d716d96d93b9d882b0c9cf00db3c6810; however, a formally tagged release version incorporating this fix has not been confirmed in the available references - operators should verify whether their specific build or downstream distribution has integrated this commit before declaring the system patched. … Detailed patch versions, workarounds, and compensating controls in full report. |
