Git up to 2.7.4 SSH URL access control

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A malicious third-party can give a crafted "ssh://..." URL to an unsuspecting victim, and an attempt to visit the URL can result in any program that exists on the victim's machine being executed. Such a URL could be placed in the .gitmodules file of a malicious project, and an unsuspecting victim could be tricked into running "git clone --recurse-submodules" to trigger the vulnerability.

The bug was discovered 08/10/2017. The weakness was disclosed 10/05/2017 as EDB-ID 42599 as confirmed exploit (Exploit-DB). The advisory is shared at exploit-db.com. The identification of this vulnerability is CVE-2017-1000117 since 10/03/2017. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

A public exploit has been developed by Metasploit and been published before and not just after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 21 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 102870 (Amazon Linux AMI : git (ALAS-2017-882)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Amazon Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 351070 (Amazon Linux Security Advisory for git: ALAS-2017-882).

Upgrading to version 2.7.5 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (42599), Tenable (102870) and SecurityFocus (BID 100283†). The entries VDB-107068, VDB-107069, VDB-107070 and VDB-107071 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
