Routine

MEDIUM 6.4MITIGATE

CVE-2022-41545 is a medium-severity flaw (CVSS 6.4) affecting c7800 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The administrative web interface of a Netgear C7800 Router running firmware version 6.01.07 (and possibly others) authenticates users via basic authentication, with an HTTP header containing a base64 value of the plaintext username and password. Because the web server also does not utilize transport security by default, this renders the administrative credentials vulnerable to eavesdropping by an adversary during every authenticated request made
