CVE: CVE-2014-2383
Vendor: dompdf
Product: dompdf
Affected version: v0.6.0
Fixed version: v0.6.1 (partial fix)
Reported by: Alejo Murillo Moyas
Details:
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:
http://example/dompdf.php?input_file=php://filter/read=convert.base64-encode/resource=<PATH_TO_THE_FILE>
