CVE-2023-24813
GHSA-56gj-mvh6-rp75 |
| Summary | Dompdf is an HTML to PDF converter written in php. Due to the difference in the attribute parser of Dompdf and php-svg-lib, an attacker can still call arbitrary URLs with arbitrary protocols. Dompdf parses the href attribute of `image` tags and respects `xlink:href` even if `href` is specified. However, php-svg-lib, which is later used to parse the svg file, parses the href attribute. Since `href` is respected if both `xlink:href` and `href` is specified, it's possible to bypass the protection on the Dompdf side by providing an empty `xlink:href` attribute. An attacker can exploit the vulnerability to call arbitrary URLs with arbitrary protocols if they provide an SVG file to the Dompdf. In PHP versions before 8.0.0, it leads to arbitrary unserialize, which will lead, at the very least, to arbitrary file deletion and might lead to remote code execution, depending on available classes. This vulnerability has been addressed in commit `95009ea98` which has been included in release version 2.0.3. Users are advised to upgrade. There are no known workarounds for this vulnerability. |

| Description | This module exploits CVE-2022-28368, a Remote Code Execution vulnerability in dompdf versions prior to 1.2.1. The vulnerability exists because dompdf preserves the original file extension when caching fonts downloaded via CSS @font-face rules. By pointing a @font-face src to a .php file containing a valid TrueType font header with embedded PHP code, the file is saved in the dompdf font cache (lib/fonts/) with its .php extension intact. The cached file can then be executed by directly requesting it from the web server. For dompdf versions <= 0.8.5, remote font loading works regardless of the $isRemoteEnabled setting. For versions 0.8.6 through 1.2.0, the $isRemoteEnabled option must be set to true. This module requires the ability to inject HTML/CSS into the data processed by dompdf (e.g., via an XSS, a user-controlled form field, or a direct parameter) and that the dompdf font cache directory is web-accessible. |
