OpenSSH RCE Vunerability: "regreSSHion"
Priority: ● High
Status: In Progress- Undergoing Analysis
First Published: 10 July 2024
Advisory Version: 2.0
References: CVE-2024-6387
Summary
A vulnerability was recently discovered in OpenSSH versions 8.5p1 to 9.8p1 that could allow an attacker to remotely execute code. This vulnerability does not affect OpenSSH versions prior to 8.5p1, and has since been patched in OpenSSH versions 9.8p1 and later.
The vulnerability stems from "sshd", the daemon program for OpenSSH, handling some signals in a way that could cause a race condition. An attacker could potentially trigger this condition, ultimately leaving the target system in an inconsistent state and vulnerable to remote, arbitrary code execution.
