CVE-2022-41545
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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 by a client to the router over a WLAN, or a LAN, should the adversary be able to perform a man-in-the-middle attack.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Netgear C7800 router's administrative web interface uses HTTP Basic Authentication, transmitting base64-encoded username and password in plaintext HTTP headers without TLS encryption. This allows network adversaries to intercept credentials via passive eavesdropping on WLAN/LAN or through man-in-the-middle attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelCheck the device label or web interface for the model number to confirm it is a Netgear C7800Affected if The device is a Netgear C7800 router
-
Check the firmware versionAccess the router's administrative web interface and navigate to the Firmware Update or Administration page to view the installed firmware versionAffected if The installed firmware version is 6.01.07
-
Verify the protocol used for admin accessAttempt to access the router admin interface using HTTP (port 80) rather than HTTPS. Observe whether the connection is established without redirect or TLS negotiationAffected if The admin interface is accessible over plain HTTP (port 80) without being redirected to HTTPS
-
Confirm TLS/HTTPS is unavailable for admin interfaceTry accessing the admin interface with https:// prefix and port 443. Check if HTTPS is rejected, fails to connect, or is not supportedAffected if HTTPS is not available or not enforced for the administrative web interface, allowing plaintext HTTP Basic Authentication to be used
You are affected if you have a Netgear C7800 router running firmware 6.01.07 and access the administrative interface over HTTP instead of HTTPS, exposing credentials in plaintext.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedEnable HTTPS/TLS transport security for the router's administrative web interface to encrypt all authentication credentials in transit. If HTTPS is not available, access the admin interface only over trusted, isolated networks.
