Erlang Erlang/OTP vulnerability
Erlang/OTP SSH server lacks authentication for critical functions, allowing unauthenticated remote code execution through malformed SSH protocol messages.
Verdict
Today item — known-exploited.
An attacker can bypass SSH authentication and execute arbitrary commands on systems running vulnerable Erlang/OTP SSH implementations without valid credentials, leading to complete system compromise.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
32 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-06-09).
Probability (EPSS)
EPSS 0.97673 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Erlang, Erlang/OTP. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-306 Missing Authentication — weakness family: Authentication.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious SSH protocol message that exploits missing authentication checks in the SSH server implementation.
Business
Attackers gain initial access to critical infrastructure without requiring valid user credentials or SSH keys.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I send the crafted message to trigger execution of arbitrary commands on the target system.
Business
Unauthorized code execution enables attackers to install malware, steal data, or establish persistent access.
3
Lateral reach — past segmentation narrative 3
Attacker
I escalate privileges and move laterally across the network using the compromised system as a pivot point.
Business
Breach scope expands beyond the initial system, potentially affecting dependent services and downstream infrastructure.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
