Summary
Statamic is a flat-first, Laravel and Git powered content management system. Prior to version 4.10.0, the SVG tag does not sanitize malicious SVG. Therefore, an attacker can exploit this vulnerability to perform cross-site scripting attacks using SVG, even when using the `sanitize` function. Version 4.10.0 contains a patch for this issue.

Summary
Statamic's Antlers sanitizer cannot effectively sanitize malicious SVG
Details
Antlers sanitizer cannot effectively sanitize malicious SVG
Summary
The SVG tag does not sanitize malicious SVG. Therefore, an attacker can exploit this vulnerability to perform XSS attacks using SVG, even when using the sanitize function.
Details
Regarding the previous discussion mentioned here, it has been identified that the default blacklist in the FilesFieldtypeController (located at this link) only blocks certain file extensions such as php, php3, php4, php5, and phtml. This allows a malicious user to upload a manipulated SVG file disguised as a social media icon, potentially triggering an XSS vulnerability.
PoC Screenshot
PoC
- Create new Global set, let's say "Settings"
- Create a "Grid" field in Blueprint (named: social), then add somefields Name (text), URL (text) and Icon (Assets) in the section Fields.
- When calling the social setting in the
_footer.antlers.html, remember to sanitize{{ settings:social }} <a href="{{ $url }}" class="ml-4" aria-label="{{ $name }}" rel="noopener"> {{ svg :src="icon" class="h-6 w-6 hover:text-hot-pink" | sanitize }} </a> {{ /settings:social }} - Upload the malicious SVG image, here is the code: ```
Statamic ```
Impact
Since the social media icon is displayed in the footer layout, any user can view it, potentially leading to the execution of XSS.
Suggestions to Mitigate or Resolve the Issue:
Sanitize when outputing the svg. This vulnerability caused by unsanitized File::get() when retrieving the SVG, it is crucial to sanitize the SVG when outputting it. The issue can be found in the following file: https://github.com/statamic/cms/blob/f806b6b007ddcf066082eef175653c5beaa96d60/src/Tags/Svg.php#L36-L40.
It is highly recommended to implement proper sanitization measures to ensure the security of the SVG content. One effective approach is to utilize a reliable package, such as https://github.com/darylldoyle/svg-sanitizer ,which provides comprehensive SVG sanitization capabilities.
So the code becomes: ```php use enshrined\svgSanitize\Sanitizer;
if (File::exists($file)) {
$sanitizer = new Sanitizer();
$dirtySVG = File::get($file);
$svg = $sanitizer->sanitize($dirtySVG);
break;
} ```
