The Article
A maximum-severity security flaw has been disclosed in the TP-Link Archer C5400X gaming router that could lead to remote code execution on susceptible devices by sending specially crafted requests. The vulnerability, tracked as CVE-2024-5035, carries a CVSS score of 10.0. It impacts all versions of the router firmware including and prior to 1_1.1.6. It has been patched in version 1_1.1.7 released on May 24, 2024.
“By successfully exploiting this flaw, remote unauthenticated attackers can gain arbitrary command execution on the device with elevated privileges,” German cybersecurity firm ONEKEY said in a report published Monday. The issue is rooted in a binary related to radio frequency testing “rftest” that’s launched on startup and exposes a network listener on TCP ports 8888, 8889, and 8890, thus allowing a remote unauthenticated attacker to achieve code execution. While the network service is designed to only accept commands that start with “wl” or “nvram get,” ONEKEY found that the restriction could be trivially bypassed by injecting a command after shell meta-characters like ; , & , or, | (e.g., “wl;id;”). Cybersecurity
TP-Link’s implemented fix in version 1_1.1.7 Build 20240510 addresses the vulnerability by discarding any command containing these special characters. “It seems the need to provide a wireless device configuration API at TP-Link had to be answered either fast or cheap, which ended up with them exposing a supposedly limited shell over the network that clients within the router could use as a way to configure wireless devices,” ONEKEY said.
The disclosure arrives weeks after security flaws were also revealed by the company in Delta Electronics DVW W02W2 industrial Ethernet routers (CVE-2024-3871) and Ligowave networking gear (CVE-2024-4999) that could allow remote attackers to gain remote command execution with elevated privileges. It’s worth noting that these flaws remain unpatched due to the devices being no longer actively maintained, making it imperative that users take adequate steps to limit exposure of administration interfaces to reduce the potential for exploitation.

People only buying this for the aesthetic in the first place and it’s pathetic.
Just buy a functional router and a Lego kit like a real adult ffs.
No one diss the gaming demon summoning circle! Sacrifice him!
I look at this thing wondering why the hell it has 9 antennas?? Or is that really just for looks? Which only raises more questions really…
Supposably for beam forming 🤷🏼♂️
I wanna see Scotty installing these on the Enterprise.
They also buy it because it is marketed for gamers telling them it gives them an advantage. Which it will if you compare it to a shitty router from 2008. Nowadays any mainstream router will do fine as long as you are within its range. If you really care as a gamer use a wired connection.
There aren't enough RGBs on this thing for me to even consider it "gaming." Step it up, TP Link!
Yeah, what’s “gaming” about this thing? Does it hate women and minorities?
Red accents of course.
And spikes
Hate the look of all these home routers.
Looks like a Daedric artifact of some sort.
Or like a Split trading station from X4
Whenever I feel like I’m a terrible programmer, I remind myself that there are vast amounts of confident coders out there being paid for code with idiotic mistakes like this and they have no intention of getting any better at it
Frankly " injecting a command after shell-metacharacters" makes it sound much more mystical and arcane than"just use the normal one liner syntax to run 2 commands"
On the plus side, this particular router will work fine as a stand for a fondue pot.
Utterly hilarious designs in the router world.
lmao just bought one of these last week! Glad the fix is already out.
And no, I didn't buy it for its looks xD It's actually a decent router that does additional things I needed.
I have one that looks just like this. Always worked pretty well for me.
Inside me there are two wolves, one that thinks “gamer” stuff is stupid, and another that thinks this router looks sweet as hell.
Just have to gibbet some dolls on those spikes
Leaving consumer routers behind and going the pfSense route is among the best decisions I’ve ever made. Highly recommended for anyone who isn’t afraid to learn some network stuff.
I’m doing this myself very soon, honestly looking forwards to it so much 😁
I remember that anticipation fondly. 😁 I watched a bunch of videos on pfSense (Lawrence Systems on YT is great, but you probably know that already) and read a bunch of things, planning out what I wanted to do before I made the leap, and it was great!
Yeah LS is truly a great resource for so many topics. Thanks for the suggestion! 🙌
I went with “cheap mikrotik router + cheap used enterprise APs (3x Aruba 325),” and I’ve been pretty happy.
What hardware you running for pfSense?
I’m running a Pentium G4560 and 8Gb of RAM in a dual NIC Shuttle case. The specs were a total gamble but I have a lot of headroom currently so if I need to do more advanced stuff in the future I can.
Same idea here. Fortigate 30f (since I can dl updates manually), Fortiswitch 124e (same) and 2 FortiAP 421E’s (ditto). All but ap’s I could grab from employers “ditch bin”.
You can run pf sense on fortinet stuff?
No. It’s proprietary custom SoC that runs heavily modified unix on ARM.
But software is solid and patches come out lightning fast.
Oh. The fortigate wasn’t one of the ones that had to be replaced because of a cvss 10 was it?
Yes and no. That model still gets updates. One I have has no active support licence, so it has to be updated manually.
I thought they had a batch of fortigate hardware whose baked in keys got leaked and their response was to recommend that affected devices be removed from service, no update fix, no patch, just “stop using them, we can’t fix it”.
Sorry for not having more information on hand, I’m on mobile at the moment and the nist database is tough to navigate with fat thumbs.
My old PC.
Its on proxmox but I’ve got an i7 8600k 18tb hard drive for frigate / nas, rtx2080ti because where else am I going to put it. 32gb ram. 1000 watt PSU.
Setting up a pfsense router / firewall virtualized in proxmox on my server PC with separate vlans for my iot devices and guest WiFi was tedious, time consuming, challenging, educational, and ultimately worth it. I’m not invincible buy at least I have fucking viability into what’s going on in my fucking home network.
Do you have any recommendations for someone looking to do this? Guides you found useful, videos or YouTube channels, software packages, pitfalls to avoid? I’ve been thinking of doing something like this for years and lately feel like I need to to get a handle on what’s really going on in my network
Dude I wish. I’d love to be able to point you in the right direction but getting this all working for me was just the product.of determination and posts / videos from all over the place.
I can tell you that adding proxmox to the equation made things way more complicated. And that vlans are not intuitive.
My advice would be to just kind of go for it. I ended up needing a smart switch, a mul5i nic pace card, a regular switch, and two access points (you could get a vlan aware access point but I couldn’t find anything that made sense price wise).
The whole thing took days to set up. I frequently didn’t know why things weren’t working. It sucked.
You can pm me if you get stuck and I can try to give you a hand buy the frustrating truth I learned about the process was that I was kind of on my own since every set up is kind of unique based on your hardware.
I’m glad its done but doing it frankly sucked…
Thanks for the reply!
I’ll probably just start messing around with things and see where they go, worst case I’ll spend some time and learn some things
Looks like a dead spider
Don’t ever buy anything marketed specifically to gamers
As a “gamer” and game developer, this is sound advice.
Yep.
At best, you’re paying extra for RGB lighting.
But what about video games :(
Compile it yourself
Donate to developers
Pro tip: Avoid routers with proprietary firmware.
OpenWrt is a nice alternative that can be installed on many devices.
I don’t see how this is possible. The router has EIGHT aerodynamic antennas.
Maybe they should have added one or two more…
