Unauthenticated RCE possible, Over 628k records stolen, Miners hidden as Edge
Let's do it.
Okay, so this one demands immediate tactical response.
We are looking at CVE-twozero2six-eightfivezero9seven.
You don't see those every day.
No, you don't.
It impacts Bricksforge, which is this really popular visual website building tool for WordPress.
And according to data from Patchstack and Wordfence, this flaw allows an unauthenticated attacker to upload and execute arbitrary PHP code.
Yeah, and that's on versions up to three point one point eight point nine.
Right.
But, um, the mechanism of how they actually bypass the security checks is what I found truly fascinating here.
Oh, it's a textbook example of how failing to validate data across a multi-step process creates just a catastrophic opening.
Yeah.
At its core, this is a remote code execution vulnerability, right? So Bricksforge has this feature that allows users to upload temporary files.
Okay.
Now, when an attacker attempts to upload a malicious payload, the application actually does its first security check perfectly.
Wait, really? It catches it at first?
Well, it tries to.
Okay.
It inspects the MIME type of the file, meaning it looks at the file structure to verify if it's genuinely an image, like, you know, a GIF or a PNG.
Right.
So in the physical world, that's kinda like a nightclub bouncer thoroughly checking your ID at the front door.
Exactly.
The system reads the top few bytes of the file, the magic bytes, as they call them, sees the signature for a GIF, and just assumes the file is totally safe.
Yep.
