Version 1.4.2 added a check `if (\\strpos($filename, 'phar://') === 0)` in the `prepareOutput` function to resolve this CVE, however if the user is able to control the second parameter of the `generateFromHtml()` function of Snappy, it will then be passed as the `$filename` parameter in the `prepareOutput()` function. In the original vulnerability, a file name with a `phar://` wrapper could be sent to the `fileExists()` function, equivalent to the `file_exists()` PHP function. This allowed users to trigger a deserialization on arbitrary PHAR files. To fix this issue, the string is now passed to the `strpos()` function and if it starts with `phar://`, an exception is raised. However, PHP wrappers being case insensitive, this patch can be bypassed using `PHAR://` instead of `phar://`. A successful exploitation of this vulnerability allows executing arbitrary code and accessing the underlying filesystem. The attacker must be able to upload a file and the server must be running a PHP version prior to 8. This issue has been addressed in commit `d3b742d61a` which has been included in version 1.4.3. Users are advised to upgrade. Users unable to upgrade should ensure that only trusted users may submit data to the `AbstractGenerator->generate(...)` function.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2023-09-06T22:18:16.000000Z"} 2023-09-06T22:18:16+00:00 https://vulnerability.circl.lu/sighting/1493da73-51ac-4167-9cd5-a007eb9c57b6/export 2026-06-05T10:12:33.995240+00:00 Joseph Lee https://cvepremium.circl.lu/user/syspect {"uuid": "1493da73-51ac-4167-9cd5-a007eb9c57b6", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2023-41330", "type": "published-proof-of-concept", "source": "https://github.com/advisories/GHSA-92rv-4j2h-8mjj", "content": "", "creation_timestamp": "2023-09-08T12:17:48.000000Z"} 2023-09-08T12:17:48+00:00
