Summary

  • A serious vulnerability (CVE-2025-32433) has been identified in certain versions of the Open Telecom Platform (OTP) in the Erlang programming language, which enables an unauthenticated remote code execution capability.
  • Palo Alto Networks has reproduced, validated and analysed this vulnerability and has observed exploitation attempts of this nature in the wild.
  • These exploitation attempts are being seen across multiple industries but there is a larger attack surface within Operational Technology (OT) networks.
  • Malicious actors are actively exploiting this vulnerability in short, high-intensity bursts that are disproportionately targeting OT networks and attempting to access exposed services over both IT and industrial ports.
  • The primary mitigation strategy is to upgrade to a patched version of OTP.
