A buffer overflow vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware <= 4.30.18.006. A stack-based buffer overflow in the Start_EPI function within the httpd binary allows an authenticated attacker with administrator privileges to execute arbitrary commands on the underlying Linux operating system as root. This vulnerablity can be triggered over the network via a malicious POST request to /apply.cgi.

An arbitrary code exection vulnerability exists in Linksys WUMC710 Wireless-AC Universal Media Connector with firmware <= 1.0.02 (build3). The do_setNTP function within the httpd binary uses unvalidated user input in the construction of a system command. An authenticated attacker with administrator privileges can leverage this vulnerability over the network via a malicious GET or POST request to /setNTP.cgi to execute arbitrary commands on the underlying Linux operating system as root.

On Linksys E5350 WiFi Router with firmware version 1.0.00.037 and lower, (and potentially other vendors/devices due to code reuse), the /SysInfo.htm URI does not require a session ID. This web page calls a show_sysinfo function which retrieves WPA passwords, SSIDs, MAC Addresses, serial numbers, WPS Pins, and hardware/firmware versions, and prints this information into the web page. This web page is visible when remote management is enabled. A user who has access to the web interface of the device can extract these secrets. If the device has remote management enabled and is connected directly to the internet, this vulnerability is exploitable over the internet without interaction.
