Some Older Linksys Routers allow UPnP Configurable from the net


Recommended Posts

very true and that is why you see many routers that have no wireless security and upnp disabled because they kept the defaults.

point being that although it is a flaw, the majority isn't succumed to this flaw being that they don't even know how to get in to it to check it's ip or if it is connected to the internet. the ones who this flaw is subject to are the people who know enough to enable it for whatever reason and should be keeping up on their security and updates.

After researching a little bit on the net. It appears as far back as the WRT54G has UPnP on by default. Now I'm not sure which version of the router finally got UPnP in the firmware or if the firmware has always had it. But which ever one does have it, has it turned on by default.

Back to the short story, this ultimately determined that the new camera had a capacity UPnP and UPnP by default. The WRT54G also has UPnP enabled by default.

Doesnt media sharing between console and computer require this to be on, or some other useful sharing? I remember a while back I had this disabled, but I wanted to share with my Xbox 360 (around the first few years it was released) and it had a fit since it was disabled.

Quite interesting...I have a wrt54g and I can assure u upnp is not on by default. I have to double check to see if it is supported, pretty sure it is not.

I don't think it should matter, ports on the router aren't blocked from internal communication just external.

Yep, go hard reset that bitch and come back with the results :laugh:

Linksys will more than likely fix this in a firmware update. But now many "Average user" upgrade the firmware of their routers?

How many "Average user" also install custom firmware?

So my guess would be we have millions of average users with linksys routers out there that are non the wiser to this issue.

Bringing us right back to

How many "average users" will share folders and

how many "average" users won't have a firewall activated on their computer.

none. For those average users there's nothing this issue can do anyway, and for those with windows 7 that automatically adds some shares if they go through the home group wizard when they connect to the network, Well that uses home group credentials and aren't accessible anyway.

Windows 7 Home Network (the one most people will use) firewall description

Home Network

Choose Home network for home networks or when you know and trust the people and devices on the network. Computers on a home network can belong to a homegroup. Network discovery is turned on for home networks, which allows you to see other computers and devices on the network and allows other network users to see your computer. For more information, see What is network discovery?

    • That is $130 more than I paid for my 4TB a year ago. How is this a deal?
    • JetBrains' new AI-first 'IDE' JetBrains Air is now on Windows by David Uzondu JetBrains has announced that JetBrains Air, its Agentic Development Environment (ADE) is now available for download on Windows x64 and ARM. You might not be familiar with JetBrains Air. It's this new desktop app that the company launched back in March 2026 to let developers hand off tasks to AI agents instead of writing every line manually. You can see it as more of an Agentic Development Environment (ADE) rather than a traditional Integrated Development Environment (IDE). The latter builds its features around a central text editor, while the former arranges everything around the AI agent itself. Here's how JetBrains describes it: Air was born from the ashes of Fleet, an experimental editor that the company quietly killed in December 2025 after realizing that competing directly with VS Code was a losing battle. The company repurposed Fleet's lightweight, modern architecture to build Air, transforming a basic code editor into a workspace for running multiple AI agents. When Air launched, it was only available for macOS. It wasn't until earlier this month that Linux users got a chance to play with the software. Now that Air is on Windows, you can do things like map out a complex feature in Plan mode and watch an AI write the implementation plan to a markdown file before writing any code. You can iterate on this plan, add references to specific classes or files, and choose whether to run the agent locally or inside an isolated Git worktree. Running agents in parallel means you can have Claude refactor a database schema in one branch while Codex writes tests in another, leaving you free to do other important things. You can even set up a pipeline where Claude writes the code, and Codex reviews it. At the moment, Air is free. If you have a JetBrains AI Pro or Ultimate subscription, you get full access to the built-in agents, though there's also the option to Bring Your Own Key (BYOK) to run APIs from Anthropic, OpenAI, or Google. If you're interested, here are the download links for both x64 and ARM64.
    • Depending how you’re wiring it internally, but try to put it inside conduit, that way in the future you can more easily replace cables, compared to running inside studs alone At least cat6a too
    • I bet Meta has lots of info on you anyway, gathered by other means. And Google, and Microsoft, and every other tech giant. If you use some form of modern electronic device, they own you already...
