FreeBSD rtsol/rtsold: RTA Domain Search Input Injection Enables Shell Cmd Exec
CVE-2025-14558 Published on March 9, 2026
Remote code execution via ND6 Router Advertisements
The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified.
resolvconf(8) is a shell script which does not validate its input. A lack of quoting meant that shell commands pass as input to resolvconf(8) may be executed.
