📄 Description (English)

Smoothwall Express versions prior to 3.1 Update 13 contain a reflected cross-site scripting vulnerability in the /redirect.cgi endpoint due to improper sanitation of the url parameter. Attackers can craft malicious URLs with javascript: schemes that execute arbitrary JavaScript in victims' browsers when clicked through the unsanitized link.

🤖 AI Executive Summary

Smoothwall Express versions before 3.1 Update 13 contain a reflected XSS vulnerability in the /redirect.cgi endpoint that allows attackers to execute arbitrary JavaScript through malicious URLs. Organizations using affected versions should immediately update to patch this vulnerability that could compromise user sessions and data.

📄 Description (Arabic)

تحتوي ثغرة XSS المنعكسة على نقطة نهاية /redirect.cgi في Smoothwall Express على معالجة غير آمنة لمعامل URL. يمكن للمهاجمين إنشاء روابط ضارة تحتوي على أكواد JavaScript التي تُنفذ في متصفح الضحية عند النقر عليها. قد يؤدي هذا إلى سرقة الجلسات أو بيانات اعتماد المستخدم أو تنفيذ إجراءات غير مصرح بها.
