More React2Shell Exploits CVE-2025-55182 – Because Apparently Patching is Optional Now

Oh bloody fantastic – another day, another avalanche of half-baked exploits making sysadmins everywhere cry into their coffee. This one’s a lovely mess dealing with React2Shell crap hammering away at CVE-2025-55182. Basically, some chuckleheads figured out they could use the same tired exploit tricks to poke at poorly maintained servers running outdated web frameworks. Guess what? It bloody works. Because nothing says “we care about security” like ignoring updates for six months and leaving your system wide open for script kiddies.

The ISC folks spotted a bump in exploit traffic aimed at this CVE, mostly hitting web servers exposed to the internet because apparently “internal only” means “wide open, no firewall, and root on public port 80.” And of course, these exploits come gift-wrapped with the usual payload crap—reverse shells, data theft, crypto-mining garbage, and other “fun” things designed to make your monitoring graphs look like a Christmas tree that’s about to explode.

In short: if your logs start looking like a horror show of base64 blobs, random shell commands, and your CPU’s suddenly hotter than Satan’s laptop, congratulations – you’ve joined the ever-growing club of “lazy bastards who didn’t patch.” The fix? PATCH THE DAMN THING. And while you’re at it, maybe stop exposing admin interfaces to the open internet like it’s 1999 and your firewall’s on permanent holiday.

Anecdote time: Reminds me of the time a dev told me, “We can’t patch, it might break production.” Next day they’re wondering why their server’s mining crypto for someone in Russia. Yeah, sure Steve, tell me more about your uptime metrics while I’m scraping ransomware off your box with a flamethrower.
