Linux Distros Unpatched Vulnerability : CVE-2018-16873

high Nessus Plugin ID 222118

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In Go before 1.10.6 and 1.11.x before 1.11.3, the go get command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). Using custom domains, it's possible to arrange things so that a Git repository is cloned to a folder named .git by using a vanity import path that ends with /.git. If the Git repository root contains a HEAD file, a config file, an objects directory, a refs directory, with some work to ensure the proper ordering of operations, go get -u can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the config file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running go get -u. (CVE-2018-16873)

Note that Nessus relies on the presence of the package as reported by the vendor.
