Title

Laravel Framework存在未明漏洞

Description

Laravel Framework是Taylor Otwell个人开发者的一款基于PHP的Web应用程序开发框架。 Laravel Framework8.70.2之前版本存在安全漏洞，该漏洞源于框架并没有充分阻止可执行PHP内容的上传，因为Illuminate/Validation/Concerns/ValidatesAttributes.php缺少对.phar文件的检查，这些文件在基于Debian的系统上被处理为application/x-httpd-php。在某些用例中，这可能与图像上传的文件类型验证有关。目前没有详细的漏洞细节提供。

CVE-2021-43617 (GCVE-0-2021-43617)

Vulnerability from cvelistv5 – Published: 2021-11-14 15:32 – Updated: 2024-08-04 04:03

NOTE: this CVE Record is for Laravel Framework, and is unrelated to any reports concerning incorrectly written user applications for image upload.

Severity

No CVSS data available.
