Description

Sshd is the OpenSSH server process. It listens to incoming connections using the SSH protocol and acts as the server for the protocol. It handles user authentication, encryption, terminal connections, file transfers, and tunneling.

What can the attacker do?

The vulnerability CVE-2024-6387 in sshd allows an attacker to execute arbitrary code on the targeted system, bypass authentication to gain unauthorized access, cause a denial of service by crashing or rendering the sshd unavailable, and exfiltrate sensitive data such as personal information and SSH keys.

Who is affected?

  • All Linux operating systems using affected versions of SSH with GNU C library : This includes popular distributions like Debian, Ubuntu, etc.

  • Servers and Applications using SSH: Any server exposed to the Internet or an internal network using SSH for remote management is at risk.

What is the vulnerability?

CVE-2024-6387 is a security vulnerability in ssd, specifically in the way certain versions of the SSH server handle logins and authentications.

There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period without user interaction.
