| Описание | The start_jffs2 function (sub_2D568) in sbin/rc retrieves the NVRAM key jffs2_exec and passes its value directly to the system() C library function. No sanitization, character filtering, escaping, or quoting is applied. An attacker who can write to NVRAM (e.g., via authenticated Web UI access or another vulnerability) can inject arbitrary shell commands that execute as root during the JFFS2 startup sequence.
v10 = nvram_get("jffs2_exec"); // 0x2D738
v11 = v10;
if (v10 && *v10) {
chdir("/jffs");
system(v11); // 0x2D75C — direct execution
chdir("/");
}
The system() function invokes /bin/sh -c <command>, so all shell metacharacters (;, &&, ||, `, $(), pipes) are interpreted. |
