| الوصف | The CIFS mount handler (sub_2D048, invoked as mount-cifs -m) in sbin/rc reads the NVRAM key cifs1 (or cifs2), parses it using < as the field delimiter via vstrsep(), and passes the 6th field (the exec command) directly to system() after a successful CIFS mount. No sanitization, filtering, or escaping is applied to any field.
// sub_2D048 at 0x2D0D8 - 0x2D310
vstrsep(s, "<", &enable, &unc, &user, &pass, &domain, &command, &servername, &security);
// ... after CIFS mount succeeds:
if (*command) {
chdir(mount_point);
system(command); // 0x2D310 — direct execution of field 6
}
The NVRAM value format is: enable<unc<user<pass<domain<EXEC_CMD<servername<security
An attacker who can modify the cifs1 or cifs2 NVRAM key can inject arbitrary shell commands in the 6th field position that execute as root when the CIFS share is mounted. |
