Vulnerability from github
Impact
A peer exposes the gRPC API and HTTP API for consumption by other peers. These APIs allow peers to send requests that force the recipient peer to create files in arbitrary file system locations, and to read arbitrary files. This allows peers to steal other peers’ secret data and to gain remote code execution (RCE) capabilities on the peer’s machine.
golang
file, err := os.OpenFile(t.DataFilePath, os.O_RDWR, defaultFileMode)
if err != nil {
return 0, err
}
defer file.Close()
if _, err = file.Seek(req.Range.Start, io.SeekStart); err != nil {
return 0, err
}
n, err := io.Copy(file, io.LimitReader(req.Reader, req.Range.Length))
Patches
- Dragonfy v2.1.0 and above.
Workarounds
There are no effective workarounds, beyond upgrading.
