Name of the Vulnerable Software and Affected Versions
OpenTelemetry-Go versions 1.15.0 through 1.42.0
Description
The fix for a previous issue changed the path used for one command but left another command vulnerable to a PATH hijacking attack on BSD and Solaris platforms. Specifically, the
kenv command is executed without an absolute path, allowing an attacker to potentially execute arbitrary code in the context of the application. This occurs when /etc/hostid does not exist, which is common on FreeBSD systems. The attack requires local access to the system. The vulnerable command is `exec.Command("kenv", ...).Recommendations
Update to version 1.43.0 or later.
