(CVE-2025-3155) Arbitrary file read by abusing ghelp scheme

https://gitlab.gnome.org/GNOME/yelp/-/issues/221

"Yelp, the GNOME user help application, allows help documents to execute
arbitrary JavaScript. A malicious help document may exfiltrate user files
to a remote server. A malicious website may download a help document
without user intervention, then trick the user into opening a ghelp URL
that references the help document. This notably requires the attacker to
guess the filesystem path of the downloaded help document."

And we just discussed old-school .HLP exploits the other day...

Here's me face talking about low-level #IBMi security:

The video also has some '90s VHS vibes to it, the writeup is still available here (minus the last temporal safety stuff):

@haroonmeer It's not that strange if you consider they speak to the low-class workers. Again, a great summary: https://www.youtube.com/watch?v=1CP9Peipxzk (note that B4B is strictily against the alt-right, yet I think they capture the core problems that the current USgov successfully capitalized)

@Newk @mrclark I think you should not attack the problem from the angle of who is being targeted: it's pretty easy to see it's everyone. IME you can get to an actual victim with one handshake, maybe two if you don't work in infosec.

It's more important to make people realize that they have shit to loose: enumerate critical assets, create estimations what damage can be done (which is what banks do as part of their compliance process). Many businesses (manufacturing is a typical example) don't realize how much they rely on IT these days.

@wdormann Yes, and this makes me think that bad guys had this exploit well before the patch:
1) APTx runs its dumbest fuzzer and writes an exploit
2) ???
3) Ivanti releases a patch
4) APTx notices their bug is burned
5) APTx goes for a aggressive campaign (or passes the exploit to low-end peers) to cash in on the patch gap.
6) Threat intel picks up ItW exploitation

With my previous comment I wanted to express my worry that we are probably in stage 2) with God knows how many Ivanti 0-days right this moment.

Hey ,
what's your best answer to people telling you "But we're not a Bank!" whenever you plan to introduce any measure to lower a risk?

@mrclark @Newk This can be a reasonable risk assessment though: take a worst case scenario, if you can recover from that with acceptable loss, do nothing. I think the hard part is get people to do the math properly, e.g. what if you have to do recovery two weeks in a row, what is the likelihood of that happening...
