Description

A vulnerability exists where a connection requiring TLS incorrectly reuses an existing unencrypted connection from the same connection pool. If an initial transfer is made in clear-text (via IMAP, SMTP, or POP3), a subsequent request to that same host bypasses the TLS requirement and instead transmit data unencrypted.

Faiblesses (CWE)

  • CWE-319 — Transmission en clair d'informations sensibles
  • CWE-295 — Validation incorrecte de certificat
