D-Link Drama: Old Router Flaws Resurface, Causing Cybersecurity Chaos!
CISA has added three old security flaws in D-Link routers to its Known Exploited Vulnerabilities catalog. These vulnerabilities, dating back to 2020, are being actively exploited. One flaw remains unpatched as the affected model is outdated. Users are advised to replace vulnerable devices before hackers turn their routers into high-tech paperweights.

Hot Take:
Who knew that dusting off old D-Link routers could lead to a treasure trove of cybersecurity vulnerabilities? It’s like finding a vintage jukebox that only plays “Hacked Again” on repeat. Perhaps it’s time to unplug those relics before they become the latest tech ‘blast from the past’ in the worst way possible.
Key Points:
- Three old security flaws impacting D-Link routers have been added to CISA’s Known Exploited Vulnerabilities catalog.
- The vulnerabilities have high severity scores, with two from 2020 and one from 2022.
- The flaws could allow remote administrator password disclosure and command injection, among other issues.
- CVE-2020-40799 has no patch since the affected model is at end-of-life.
- Federal agencies must mitigate these vulnerabilities by August 26, 2025.
