OK, Rocket Software believes that the likelihood of my unauthenticated RCE "being exploited is rare"...🤦‍♂️

Nah, it's only been a very vivid fever dream. It never happened, for sure 😬

Another day, another Remote Code Execution (and its 3 friends).

Pre-auth path traversal, hard-coded crypto key allowing cookie forgery, arbitrary file write, and PII disclosure in TRUfusion Enterprise (CVE-2025-27222 to CVE-2025-27225) #security

Remember I wanted to drop more bugs (Pre-Auth RCE, Cookie Forgery etc.) in June?

Unfortunately, I had to postpone the disclosure because there are still too many vulnerable instances online and the vendor apparently needs to manually patch each one... 🤦‍♂️

I‘d say it’s gonna be option one 🤪 Norway is one of the most beautiful countries on this planet 👌

Yeah, I mean it really depends how you’re using it. Personally, Notion was more of an overpriced idea dump with project management for me. So switching it to Stackfield wasn’t that much of a change 🤷‍♂️
mrtuxracer.bsky.social
Although self-hosted Obsidian would do it too 👍
mrtuxracer.bsky.social
I‘m abusing my Stackfield instance for that 😏

In terms of that, big shout-out to @proton.me for their stance on #privacy and for their Mail/Drive/Pass products that are a perfect alternative to some of these products! Cheers guys! Appreciate your hard work!

I am a huge fan of the #BuyFromEU movement! So far, I've ditched a lot of US stuff already, including Microsoft, Dropbox, 1Password, Notion, Grammarly, Amazon, Slack, and Google.

Here's an update to the blog post about CVE-2025-47812, which now includes a way to leak a user's password (CVE-2025-27889), but requires a bit of social engineering.

We've just updated our latest blog post about CVE-2025-47812 to include another disclosure that went a little under the radar but could be used to leak a user's password: CVE-2025-27889.

What the NULL?! Wing FTP Server RCE (CVE-2025-47812) | RCE Security

As promised! Here's a root/SYSTEM-level RCE (aka CVE-2025-47812) affecting Wing FTP Server in versions before 7.4.4.

Enjoy 🥷

During a customer pentest, we went from anonymous Read-Only FTP access to full root-level remote code execution by abusing a string parsing discrepancy in Wing FTP's username handling.

I'll publish 4 CVEs later today, including one unauthenticated Root/SYSTEM-level RCE.

I'm a bit nervous, TBH, because it potentially affects 15k systems on the internet. But, according to the vendor, most instances should've been updated already 😬

I don’t know why, but this has some very strong jonathandata vibes 😬

A missing SPF record chained with sending an email leading to critical content injection? 🤯
mrtuxracer.bsky.social
Yep, he does this stuff 👍
mrtuxracer.bsky.social
Totally understandable 😬

It caused a long sequence of WTFs on my face when I found it.

I have plenty of public disclosures planned for June:

2x RCE (one as root!),
Full SSRF,
Directory traversal,
Cookie forgery leading to auth bypass,
Multiple information disclosures incl. PII
Link injection leaking clear-text passwords

All pre-auth 🙃
