Description

This security bulletin contains information about 2 vulnerabilities.


1) OS command injection (CVE-ID: CVE-2017-1000117)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber


The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The weakness exists due to command injection flaw. A remote attacker (e.g., repository) can return a specially crafted 'ssh://' URL during 'clone' commands to execute arbitrary shell commands with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

2) Privilege escalation (CVE-ID: CVE-2017-8386)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote authenticated attacker to gain elevated privileges on the target system.

The weakness exists due to an error when handling command-line options for the restricted set of git-shell commands. A remote attacker can use a repository name that starts with a - (dash) character to bypass git-shell restrictions and gain elevated privileges.

Successful exploitation of the vulnerability results in access to the system and information disclosure.
