CVE-2022-46569
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 · uneditedD-Link DIR-882 DIR882A1_FW130B06, DIR-878 DIR_878_FW1.30B08 was discovered to contain a stack overflow via the Key parameter in the SetWLanRadioSecurity module.
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 · moderate confidenceStack-based buffer overflow vulnerability in D-Link DIR-882 and DIR-878 routers in the SetWLanRadioSecurity module. The Key parameter does not properly validate input length before copying to a stack buffer, allowing an authenticated attacker to overflow the buffer and potentially execute arbitrary code.

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 router modelCheck the device label or web interface status page to confirm the router is a D-Link DIR-882 or DIR-878 model.Affected if The router is a DIR-882 or DIR-878 model.
-
Check firmware versionLog into the router web interface, navigate to Status or System settings, and locate the firmware version field. Compare against 1.30b06 for DIR-882 A1.Affected if Firmware version is 1.30b06 on DIR-882 A1, or any unpatched version on DIR-878.
-
Verify web management accessCheck router web interface under Administration or System settings for Remote Management/Remote Admin settings. Determine if HTTP/HTTPS management is accessible from WAN (internet) side.Affected if Remote management is enabled and accessible from WAN, making the device potentially exploitable over the network.
-
Confirm authentication statusDetermine if default admin credentials have been changed and if the web interface is accessible to untrusted users.Affected if The web interface is accessible to authenticated attackers, which is required for exploiting this vulnerability.
The device is affected if it is a D-Link DIR-882 or DIR-878 running the vulnerable firmware and the web management interface is accessible to authenticated users.

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.
From vendor dataApply vendor-supplied firmware updates when available. Until patched, restrict access to the router's web management interface to trusted networks or disable remote management. Verify wireless security settings after any firmware update.
