Local command injection via wrapper argument parsing
Published Oct 24, 2023 · Updated Aug 2, 2024
Command injection in Traceroute for Linux 2.0.12 through 2.1.2 allows local users to execute shell commands via wrapper arguments. The tcptraceroute, tracepath, traceproto, and traceroute-nanog wrappers pass attacker-controlled arguments through getopt without the -- separator and then evaluate the parsed text with eval, causing shell metacharacters to become commands. The injected command runs with the wrapper's privileges; root execution requires an affected wrapper to be authorized and invoked through sudo.
