Detailsinfo

A vulnerability was found in Asus WRT 3.0.0.4.376.2524-g0012f52. It has been declared as very critical. Affected by this vulnerability is some unknown functionality of the file common.c. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

common.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U, RT-N66U, and other routers, does not properly check the MAC address for a request, which allows remote attackers to bypass authentication and execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port 9999. NOTE: this issue was incorrectly mapped to CVE-2014-10000, but that ID is invalid due to its use as an example of the 2014 CVE ID syntax change.

The weakness was disclosed 01/08/2015 (Website). The advisory is shared at github.com. This vulnerability is known as CVE-2014-9583 since 01/08/2015. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/04/2024). MITRE ATT&CK project uses the attack technique T1068 for this issue.

A public exploit has been developed by Friedrich Postelstorfer and been published before and not just after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 80518 (ASUS Router 'infosvr' Remote Command Execution), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Backdoors and running in the context r. The analysis with Nessus happens with this NASL code:

s = open_sock_udp(port);
if (!s) audit(AUDIT_SOCK_FAIL, port, "udp");

timeout = get_read_timeout() * 1000;

wps_mfstring = run_command(udp_socket:s, command:"nvram get wps_mfstring", timeout:timeout);

if ("ASUS" >!< wps_mfstring) audit(AUDIT_NOT_LISTEN, "The ASUSWRT 'infosvr' service", port, "udp");

user = run_command(udp_socket:s, command:"nvram get http_username", timeout:timeout);
pass = run_command(udp_socket:s, command:"nvram get http_passwd", timeout:timeout);

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (35688), Tenable (80518), SecurityFocus (BID 71889†) and Vulnerability Center (SBV-47995†). The entries VDB-66155 and VDB-72805 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
