Frequently Asked Questions

Product Information & CVE-2024-6387

What is CVE-2024-6387 (regreSSHion) and why is it significant?

CVE-2024-6387, also known as regreSSHion, is an unauthenticated remote code execution vulnerability in OpenSSH’s server. It allows attackers to gain full root access without user interaction and affects the default configuration. This vulnerability is a regression of a previously patched issue (CVE-2006-5051) and poses a significant exploit risk, especially for 32-bit systems where a public exploit exists. For more details, see the National Vulnerability Database.

Which OpenSSH versions are affected by CVE-2024-6387?

Versions earlier than 4.4p1 are vulnerable unless patched for CVE-2006-5051 and CVE-2008-4109. Versions from 4.4p1 up to (but not including) 8.5p1 are not vulnerable. Versions from 8.5p1 up to (but not including) 9.8p1 are vulnerable. Upgrading to OpenSSH 9.8p1 or later resolves the issue. See the OpenSSH 9.8p1 Release Notes for details.

New CVE Detected

CVE-2024-6387 – OpenSSH Unauthenticated Remote Code Execution (regreSSHion)

CVE-2024-6387, also known as regreSSHion, is an unauthenticated remote code execution vulnerability in OpenSSH’s server that grants full root access. It affects the default configuration and does not require user interaction. It poses a significant exploit risk. A crude public exploit does exist for 32-bit systems, but not 64-bit systems.

This vulnerability is a regression of the previously patched vulnerability CVE-2006-5051, reported and fixed in 2006. Due to this uncommon vector of a code regression (re)creating a vulnerability, the versions of OpenSSH sshd are affected is strange: Versions earlier than 4.4p1 are vulnerable unless they have already been patched for CVE-2006-5051 and CVE-2008-4109. Versions from 4.4p1 up to, but not including, 8.5p1 are not vulnerable. Versions from 8.5p1 up to, but not including, 9.8p1 vulnerable.

To resolve the issue, upgrade to the latest version of OpenSSH.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
