CVE-2016-3069

28
FAUCET Score

CVE-2016-3069 describes a critical vulnerability in Mercurial versions prior to 3.7.3, allowing remote attackers to execute arbitrary code. This flaw is triggered by a crafted name during the conversion of a Git repository and affects various distributions including Debian, Fedora, openSUSE, Red Hat, and SUSE. With a CVSS score of 8.8 (High), it presents a significant risk due to its network-based attack vector, low attack complexity, and high potential for complete compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
