CVE-2019-6487
TP-Link WDR Series devices through firmware v3 (such as TL-WDR5620 V3.0) are affected by command injection (after login) leading to remote code execution, because shell metacharacters can be included in the weather get_weather_observe citycode field.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
