LOW 2.1EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) fail to include the X-Content-Type-Options: nosniff response header on web management interfaces. As a result, browsers that perform MIME sniffing may incorrectly interpret attacker-influenced responses as executable script.
