CVE-2019-3464 describes a critical vulnerability in rssh, a restricted shell designed to limit users to rsync operations. Insufficient sanitization of environment variables allows attackers to bypass these restrictions and execute arbitrary shell commands, affecting canonical, debian, fedoraproject, and pizzashack products. With a CVSS score of 9.8 (Critical), this vulnerability has a network attack vector, low attack complexity, and can lead to complete compromise of confidentiality, integrity, and availability. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered some community discussion and media coverage, including a mention in a SecurityWeek article.
