Faigheann taighdeoir leochaileachtaí iomadúla i dhá ródaire Netgear Nighthawk

A security researcher has discovered a total of 11 serious vulnerabilities in recent firmware updates for the Netgear Nighthawk routers. The vulnerabilities have been patched by Netgear. For example, the routers store usernames and passwords in plaintext.

Is in Nighthawk R6700v3 AC1750- na leochaileachtaí a fuair an taighdeoir Jimi Sebree de chuid na cuideachta slándála Tenableleagan Firmware 1.0.4.120 and in the Nighthawk RAX43, firmware version 1.0.3.96. The vulnerabilities vary, but are all serious to critical according to the researcher, and furthermore not all have been patched by Netgear.

The most critical vulnerability is registered as CVE-2021-45077 for the RS6700 and CVE-2021-1771 for the RAX43. The routers store usernames and passwords for the device and provided services in plaintext on the routers, also the admin password is in plaintext in the primary configuration file of the router, Scríobhann Sebree ar a láithreán gréasáin.

In addition, there is a risk that those usernames and passwords will be intercepted. In the RS6700v3, because the routers úsáid chaighdeánach HTTPand, instead of Https, for all communication with the web interface. Also the SOAP interface, on port 5000, úsáideann HTTP le haghaidh cumarsáide, ag ligean do na pasfhocail agus na hainmneacha úsáideora a idircheapadh.

Ina theannta sin, tá an ródaire i mbaol instealladh ordú trí earráid instealladh ordú iar-fhíordheimhnithe in the update software of the device. Triggering an update check through the SOAP interface leaves the device vulnerable to takeover via preconfigured values. Also, the UART console cosanta a dhóthain, a ligeann do dhuine ar bith a bhfuil rochtain fhisiciúil acu ar an bhfeiste tríd an gcalafort UART chun tascanna a nascadh agus a chomhlíonadh mar úsáideoir fréimhe gan fíordheimhniú.

Also, the router uses hard-coded credentials for certain settings, so that a user cannot normally adjust certain security settings. These are encrypted, but according to the researchers sách éasca a fháil with publicly available tools, allowing settings to be adjusted by anyone with access to the router. In addition, the router exploits several known vulnerabilities in jQuery libraries and in minidlna.exe, while more recent versions are available.

The vulnerabilities in the RS6700 have a CVE score of 7.1 on a scale of 1 to 10. That’s serious, but not critical. The main reason is that an attacker must have physical access to the router in order to exploit the vulnerabilities. In addition, exploiting the vulnerabilities in the SOAP interface is only possible if an attacker is already logged in. The vulnerabilities for the RAX43 have a score of 8.8 out of 10.

Úsáideann an RAX43 HTTP freisin de réir réamhshocraithe, scríobhann Sebree, and the uses the same bad jQuery libraries and vulnerable version of minidlna.exe. In addition, the RAX43 firmware has a vulnerability caused by two bugs. The first is a buffer overrun vulnerability, the second a command injection vulnerability. Combining the two allows someone to perform remote tasks as root, without authentication.

Sebree writes that Tenable has notified Netgear of the vulnerabilities on September 30. Although Netgear initially responded to the report of the vulnerabilities in early October, it took a long time before anything was done about it. December 29, Netgear rabhadh do na leochaileachtaí a chur ar líne. There are also now nuashonruithe firmware don dá routers put online. Sebree decided on December 30 to disclose the vulnerabilities under the guise of responsible disclosure, even though Netgear has not yet actively pushed the firmware updates to users.

The Nighthawk RS6700 is a series of routers mainly aimed at home use. It is listed as the AC1750 Smart WiFi Router in the Pricewatch, and has been available since July 31, 2019. The vulnerabilities are in the an tríú leagan den ródaire. The RAX43 has been available since December 30, 2020.
