Description
This security bulletin contains information about 2 vulnerabilities.
1) OS command execution (CVE-ID: CVE-2018-7187)
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:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The weakness exists in the "go get" implementation due to insufficient validation of the import path (get/vcs.go only checks for "://" anywhere in the string) when the -insecure command-line option is used. A remote attacker can trick the victim into visiting a specially crafted website, inject OS commands and execute arbitrary code.
2) Command injection (CVE-ID: CVE-2018-6574)
CWE-ID: CWE-77 - 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:P/U:Clear
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The weakness exists due to "go get" remote command execution during source code build, by leveraging the gcc or clang plugin feature, because -fplugin= and -plugin= arguments were not blocked. A remote attacker can execute arbitrary commands.
