No affected components available
URLs and local file paths passed to the Mercurial (hg) APIs that are specially crafted can contain commands which are executed by Mercurial if it is installed on the host operating system. The vcs package uses the underly version control system, in this case hg, to implement the needed functionality. When hg is executed, argument strings are passed to hg in a way that additional flags can be set. The additional flags can be used to perform a command injection. Other version control systems with an implemented interface may also be vulnerable. The issue has been fixed in version 1.13.2. A work around is to sanitize data passed to the vcs package APIs to ensure it does not contain commands or unexpected data. This is important for user input data that is passed directly to the package APIs.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
