Research update for HackTricks content

🤖 Agent Actions

I’m starting with the target page and nearby HackTricks content to pin down what is already covered before I add anything. After that I’ll do current-source research on phpinfo-assisted LFI to RCE and only keep techniques that materially improve this page.
The page is already solid on the classic race. I’m checking the other LFI2RCE pages now to avoid copying content that belongs in the generic LFI page or in the temp-upload/session variants instead of this phpinfo-specific page.
I’ve separated what belongs to this page: modern constraints around output buffering, HTTP stacks, and practical parsing/targeting notes that are specific to phpinfo disclosure. Next I’m validating those points against current sources and recent writeups instead of repeating the older whitepaper.
I have enough local context. Now I’m pulling the source material behind a few credible hits: PHP’s own buffering docs for what still governs the race, plus lab/writeup material that shows how operators are adapting the exploit on modern stacks.
The recent searches are converging on the same useful signal: the exploit still works in modern labs, but reliability now depends more on buffering across PHP, FastCGI, and the reverse proxy than on PHP version alone. I’m extracting the exact points I can support cleanly before editing the page.
I’m at the edit point. The changes will stay tight: one new reconnaissance section for what to read directly from phpinfo(), and a buffering-focused reliability section so the page reflects how this attack behaves on modern PHP/FPM stacks without duplicating the generic LFI2RCE pages.
The file is updated. I’m doing a final readback and diff now to verify the new sections land cleanly, the references stay at the end, and I didn’t accidentally blur this page into the other LFI2RCE techniques.
One cleanup before I close this out: the page already had a training banner after ## References, which violates the user’s “references last” requirement. I’m moving that include so the file ends on the reference list without changing any substantive content.
Updated lfi2rce-via-phpinfo.md with phpinfo-specific reconnaissance and modern reliability notes rather than generic LFI2RCE content. I added a new section on what to read directly from phpinfo() before racing (file_uploads, upload_tmp_dir, open_basedir, output_buffering, compression/handlers, Server API), expanded troubleshooting around buffering/proxy behavior, and added a short “modern stacks” section explaining that the technique still works in current labs but is now mostly constrained by buffering layers, not by a phpinfo-specific fix.

I also kept ## References as the last section and added only two new references there: PHP’s output flushing docs and Vulhub’s reproducible PHPINFO lab. I verified the final diff after editing.
