Vulnerability title: Arbitrary File Read In dompdf

CVE: CVE-2014-2383
Vendor: dompdf
Product: dompdf
Affected version: v0.6.0
Fixed version: v0.6.1 (partial fix)
Reported by: Alejo Murillo Moya


An arbitrary file read vulnerability is present on dompdf.php file that allows remote or local attackers to read local files using a special crafted argument. This vulnerability requires the configuration flag DOMPDF_ENABLE_PHP to be enabled (which is disabled by default).

Using PHP protocol and wrappers it is possible to bypass the dompdf’s “chroot” protection (DOMPDF_CHROOT) which prevents dompdf from accessing system files or other files on the webserver. Please note that the flag DOMPDF_ENABLE_REMOTE needs to be enabled.

Command line interface:
php dompdf.php php://filter/read=convert.base64-encode/resource=<PATH_TO_THE_FILE>

Web interface:


A successful attack could allow an attacker to bypass the dompdf’s “chroot” protection (DOMPDF_CHROOT) which prevents dompdf from accessing files outside the folder stated in the configuration file.

Effectively, this vulnerability is able to bypass two implemented protections:

- DOMPDF_ENABLE_REMOTE (as it is possible to access local resources)

- DOMPDF_CHROOT (as local files outside the chroot can be read)


Exploit code not required.
