Sources and claim methodology

  • GitHub security advisorygithub.com
  • Source referencevulncheck.com
Upstream source description

Scapy before 2.7.0 contains an insecure deserialization vulnerability in the load_session function that allows attackers to execute code by supplying a malicious pickle session file. Attackers can trick users into loading a crafted .pkl.gz file via the -s option or conf.session, executing embedded Python code through __reduce__().
