Detailsinfo

A vulnerability has been found in Netgear Nighthawk X10-R900 up to 1.0.4.25 and classified as critical. This vulnerability affects an unknown code of the component SOAP Endpoint. The manipulation as part of a Environment Variable leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In NETGEAR Nighthawk X10-R900 prior to 1.0.4.26, an attacker may execute arbitrary system commands as root by sending a specially-crafted MAC address to the "NETGEAR Genie" SOAP endpoint at AdvancedQoS:GetCurrentBandwidthByMAC. Although this requires QoS being enabled, advanced QoS being enabled, and a valid authentication JWT, additional vulnerabilities (CVE-2019-12510) allow an attacker to interact with the entire SOAP API without authentication. Additionally, DNS rebinding techniques may be used to exploit this vulnerability remotely. Exploiting this vulnerability is somewhat involved. The following limitations apply to the payload and must be overcome for successful exploitation: - No more than 17 characters may be used. - At least one colon must be included to prevent mangling. - A single-quote and meta-character must be used to break out of the existing command. - Parent command remnants after the injection point must be dealt with. - The payload must be in all-caps. Despite these limitations, it is still possible to gain access to an interactive root shell via this vulnerability. Since the web server assigns certain HTTP headers to environment variables with all-caps names, it is possible to insert a payload into one such header and reference the subsequent environment variable in the injection point.

The weakness was presented 02/24/2020. This vulnerability was named CVE-2019-12511 since 06/01/2019. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1202.

Upgrading to version 1.0.4.26 eliminates this vulnerability.
