### Summary The URI validation on dompdf 2.0.1 can be bypassed on SVG parsing by passing `<image>` tags with uppercase letters. This might leads to arbitrary object unserialize on PHP < 8, through the `phar` URL wrapper. ### Details The bug occurs during SVG parsing of `<image>` tags, in src/Image/Cache.php : ``` if ($type === "svg") { $parser = xml_parser_create("utf-8"); xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, false); xml_set_element_handler( $parser, function ($parser, $name, $attributes) use ($options, $parsed_url, $full_url) { if ($name === "image") { $attributes = array_change_key_case($attributes, CASE_LOWER); ``` This part will try to detect `<image>` tags in SVG, and will take the href to validate it against the protocolAllowed whitelist. However, the `$name comparison with "image" is case sensitive, which means that such a tag in the SVG will pass : ``` <svg> <Image xlink:href="phar:///foo"></Ima...
Dompdf is an HTML to PDF converter. The URI validation on dompdf 2.0.1 can be bypassed on SVG parsing by passing `<image>` tags with uppercase letters. This may lead to arbitrary object unserialize on PHP < 8, through the `phar` URL wrapper. An attacker can exploit the vulnerability to call arbitrary URL with arbitrary protocols, if they can provide a SVG file to dompdf. In PHP versions before 8.0.0, it leads to arbitrary unserialize, that will lead to the very least to an arbitrary file deletion and even remote code execution, depending on classes that are available.
