Description

On certain TOTOLINK Realtek SDK based routers, an authenticated attacker may execute arbitrary OS commands via the sysCmd parameter to the boafrm/formSysCmd URI, even if the GUI (syscmd.htm) is not available. This allows for full control over the device's internals. This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, N100RE through 3.4.0, and N302RE 2.0.2.

Affected configurations

• totolink a3002ru firmware (<= 2.0.0) • totolink a702r firmware (<= 2.1.3) • totolink n301rt firmware (<= 2.1.6) • totolink n302r firmware (<= 3.4.0) • totolink n300rt firmware (<= 3.4.0) • totolink n200re firmware (<= 4.0.0) • totolink n150rt firmware (<= 3.4.0) • totolink n100re firmware (<= 3.4.0)
