Practical exploitability of BrainFlow analyser findings

Establish whether the triaged externally controlled format-string sites and potential memory-corruption sites identified in BrainFlow 5.18.0 are exploitable in practice, including whether they can support a working control-flow hijack or arbitrary code execution.

Background

The system-security analysis identified 34 externally controlled format-string sites and 317 potential memory-corruption sites in BrainFlow 5.18.0. These were static-analyser candidates rather than confirmed exploitable vulnerabilities.

The authors dynamically confirmed that OpenBCI GUI helper components run without privilege separation, but they did not establish control-flow hijacking or arbitrary code execution from the identified sites. Determining the practical exploitability of the triaged findings is explicitly deferred.

References

We did not develop a working control-flow hijack from these sites, and we therefore make no claim of arbitrary code execution. What we confirmed dynamically is narrower but concrete: the OpenBCI GUI invokes BrainFlow helper components without privilege separation, so code executing inside a helper inherits the launching process's privileges rather than a reduced set. Establishing whether the triaged sites are exploitable in practice is left to future work; all findings were reported to the maintainers (Section~\ref{sec:disclosure}).
