Security Bulletin
This security bulletin contains one high risk vulnerability.
EUVDB-ID: #VU15167
Risk: High
CVSSv3.1: 9.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2018-17456
CWE-ID:
CWE-77 - Command injection
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The weakness exists in the Git command line client, Git Desktop, and Atom due to command injection during processing of a recursive "git clone" of a superproject if a .gitmodules file has a URL field beginning with a '-' character.. A remote attacker can use a specially crafted.gitmodules file that contains an URL that starts with a dash. By using a dash, when Git clones a repository using the --recurse-submodules argument, the command will interpret the URL as an option that can be used to execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
The vulnerability has been fixed in Git 2.19.1 (with backports in 2.14.5, 2.15.3, 2.16.5, 2.17.2, and 2.18.1), GitHub Desktop 1.4.2 and 1.4.3-beta0, and Atom 1.31.2 and 1.32.0-beta3.
Vulnerable software versionsGit: 2.0.0 - 2.19.0
GitHub Desktop: 1.2.6 - 1.4.1
Atom: 1.26.1 - 1.31.1
