Tenda Router’s Epic Fail: Stack Overflow Unplugged!
A buffer overflow vulnerability in the Tenda FH451 router could lead to a service crash, bringing your network down faster than your in-laws at Thanksgiving. Exploitable via an unauthenticated POST request, CVE-2025-7795 offers hackers a buffet of chaos without even needing a password.

Hot Take:
Looks like Tenda routers are having a bit of an identity crisis—do they want to be routers or crash test dummies? With a vulnerability like CVE-2025-7795 lurking, these routers might just be the new “blue screen of death” for network hardware. Is it a bird? Is it a plane? No, it’s a stack-based buffer overflow taking your router down faster than you can say “Oops, I did it again.” Unauthenticated POST requests have never been this scandalous. Britney Spears would be proud.
