Nr1800x Firmware

Buffer overflow in Totolik NR1800X firmware allows authenticated remote attackers to achieve complete system compromise through malformed SSID parameters in the setWizardCfg POST handler. Public exploit code is available and no patch has been released, leaving affected devices vulnerable to remote code execution. This vulnerability requires valid credentials but presents critical risk given the device's network exposure and lack of mitigation options.

Totolik NR1800X firmware versions up to 9.1.0u.6279_B20210910 contain a command injection vulnerability in the setTracerouteCfg function that allows authenticated remote attackers to execute arbitrary commands via malicious POST requests. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker with valid credentials can leverage this to achieve remote code execution on affected network devices.

Command injection in Totolik NR1800X firmware allows authenticated remote attackers to execute arbitrary commands through the Hostname parameter in the setWanCfg POST handler. Public exploit code exists for this vulnerability, creating elevated risk despite no patch availability. Affected devices can be compromised to gain full system control with network access and valid credentials.
