What CVE-2025-32433 Is and Why It Matters ?
A new critical vulnerability—CVE-2025-32433, also known as the Erlang SSH Chainbreaker—allows attackers to execute commands without authentication. This video breaks down what the flaw is, how the exploit works, why it’s dangerous, and which systems are at risk.
🔍 In Part 1, you’ll learn:
- How a logic bug in Erlang’s SSH server accepts pre-auth packets
- Why this leads to Remote Code Execution (RCE)
- How attackers exploit it: scan → send payload → gain shell → spread
- Which platforms may be affected (RabbitMQ, telecom systems, IoT, cloud apps, etc.)
- Key Indicators of Compromise (IOCs) to watch for
- Why CISA added this CVE to the Known Exploited Vulnerabilities (KEV) list
⚠️ Severity: CVSS 10.0 — Exploited in the wild
⚠️ Risk: Full host compromise, data theft, operational disruption
🛡️ What to do now:
Update Erlang OTP immediately, restrict or disable SSH, and block external access to vulnerable systems.
