- 0.21.2· Vendor fix available
- Issue
- deserializing json data using qiskitibmruntime.RuntimeDecoder can be made to execute arbitrary code given a correctly formatted input string Details RuntimeDecoder is supposed to be able to deserialize JSON strings containing various special types encoded via RuntimeEncoder. However, one can structure a malicious payload to cause the decoder to spawn a subprocess and execute arbitrary code, exploiting this block of code: https://github.com/Qiskit/qiskit-ibm-runtime/blob/16e90f475e78a9d2ae77daa139ef750cfa84ca82/qiskitibmruntime/utils/json.py#L156-L159 PoC (where obviously "echo hi" can be replaced with something much more malicious) notably the following also makes it through the runtime API, with maliciousdata serialized client-side via RuntimeEncoder (and therefore presumably deserialized server-side via RuntimeDecoder?) Impact i don't know if qiskitibmruntime.RuntimeDecoder is used server-side so this may or may not be a serious vulnerability on your end (however it's…
Recommended action: Upgrade to 0.21.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
