description: "Adobe Reader 7.0 ships ENUtxt.pdf at a fixed path, so a file:/// URL to it with #blah=javascript:alert() executes script from the local zone in Firefox and Opera. Turns the remote PDF-XSS class into a local one needing no attacker-hosted PDF."

## [PDF XSS Can Compromise Your Machine](http://ha.ckers.org/blog/20070103/pdf-xss-can-compromise-your-machine/)

Okay, I spent exactly 5 minutes looking at my machine before I found a default file that is included with Adobe Acrobat Reader 7.0. It’s located at file:///C:/Program%20Files/Adobe/Acrobat%207.0/Resource/ENUtxt.pdf and it is a valid location. Great. So let’s see if it’s vulnerable to the XSS DOM injection:

file:///C:/Program%20Files/Adobe/Acrobat%207.0/Resource/ENUtxt.pdf#blah=javascript:alert("XSS");

Hmmm… It would appear that Adobe Acrobat has now created a local JavaScript issue for Firefox and Opera users. I’m sure there are other default locations for other versions of Adobe Acrobat. Very scary stuff.

## Recovery notes

Source evidence recovered on 2026-09-14. The earlier source capture (SHA-256 `4341fcba21876ec3d366d09ffcb3da1feb3ed0138da0eec1265d458470b6ff77`) is no longer available. This publication uses a separately preserved capture of the same document recorded on 2026-08-09 (SHA-256 `8d71af25bcb8dffd6990cb72cc825350e04d121f338564b01f94b4101706570c`). The retained article text was checked against this replacement capture. Complete retained post agrees, including Acrobat7 ENUtxt.pdf location and literal #blah=javascript fragment demonstration. Existing capture-quality limitations remain recorded separately. The missing earlier capture remains documented in the archive history.
