CVE-2020-17367

20
FAUCET Score

CVE-2020-17367 describes a command injection vulnerability in Firejail through version 0.9.62, affecting products like Debian, Fedora, and OpenSUSE. This high-severity flaw (CVSS 7.8) allows a local attacker to execute arbitrary commands due to Firejail failing to properly handle the end-of-options indicator after the --output option, potentially leading to full compromise of confidentiality, integrity, and availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
