CVE-2022-35572
This web page is visible when remote management is enabled.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
