TP-Link Wi-Fi Extender Vulnerability: A Blast from the Past Haunts Networks!

Hot Take:

Looks like TP-Link’s TL-WA855RE Wi-Fi extender is extending more than just your Wi-Fi coverage—it’s also extending a warm welcome to cyber attackers! While the tech world has moved on, CISA is bringing this oldie-but-baddie back into the spotlight. It’s like finding out your VCR is a secret spy device; you didn’t even know it was still relevant, did you?

Key Points:

• TP-Link’s TL-WA855RE Wi-Fi extender has a vulnerability (CVE-2020-24363) allowing unauthorized factory resets and reboots.
• The flaw lets attackers on the same network set a new admin password without authentication.
• This vulnerability was patched over half a decade ago, but the product is now discontinued.
• CISA added the vulnerability to its Known Exploited Vulnerabilities catalog alongside a WhatsApp zero-day.
• Users are advised to stop using the device as it is end-of-life and end-of-service.

Wi-Fi Woes: The Saga Continues

In a plot twist that surprises absolutely no one paying attention, TP-Link’s TL-WA855RE Wi-Fi extender has been caught with its digital pants down. The same vulnerability that haunted it in 2020, CVE-2020-24363, has re-emerged like an awkward high school yearbook photo. This flaw, which allows attackers to bypass authentication and reset the device’s settings, is like finding out your grandma’s rotary phone is a hot commodity for hackers. Seriously, who knew?

A Blast from the Past

Remember the good ol’ days of 2020? You know, when TP-Link had already patched this little hiccup with a firmware update? Well, it turns out some TL-WA855RE extenders are still out there in the wild, like rare Pokémon that need to be caught—except in this case, they need to be retired. CISA, the cybersecurity sheriff in town, is now wrangling these outdated gadgets back into the spotlight. So if you’ve been clinging to your TL-WA855RE like it’s a vintage treasure, it’s time to let it go.

Why You Should Care

While it might seem like a relic of the past, this vulnerability is like a ghost that refuses to leave the haunted house that is your network. An attacker on the same network could easily reset your device and set a new password, essentially taking control of your Wi-Fi extender. Think of it as leaving your front door wide open with a “Welcome, Hackers!” mat. Unless you’re into that sort of thing, it’s time to upgrade.

CISA’s Call to Action

In a move that says “better late than never,” CISA has added this vulnerability to its Known Exploited Vulnerabilities catalog. They’re urging federal agencies to address this and a WhatsApp zero-day by September 23. It’s like getting a last-minute invitation to the cybersecurity party, and now everyone has to scramble to find a gift—or in this case, a fix. If you still have one of these extenders, consider it your cue to exit stage left.

Outdated and Outclassed

This tale of Wi-Fi woe serves as a gentle reminder that even tech with a senior citizen discount can still find its way into the hands of opportunistic cyber attackers. The TL-WA855RE is now as discontinued as a limited-edition seasonal latte, and just as irrelevant. So if you’re still holding onto one, it might just be time to upgrade to something a little less… vulnerable. After all, no one wants their Wi-Fi extender to be the punchline of a cybersecurity joke.

So there you have it, folks! A blast from the past that proves some tech never truly dies—it just gets a second chance to haunt your network. Stay safe, stay updated, and remember: in the world of cybersecurity, retirement isn’t just for people—it’s for outdated gadgets, too.
