📄 Description (English)
WebSSH for iOS 14.16.10 contains a denial of service vulnerability in the mashREPL tool that allows attackers to crash the application by pasting malformed input. Attackers can trigger the vulnerability by copying a 300-character buffer of repeated 'A' characters into the mashREPL input field, causing the application to crash.
🤖 AI Executive Summary
WebSSH for iOS 14.16.10 contains a denial of service vulnerability in the mashREPL tool that allows attackers to crash the application through malformed input. An attacker can trigger the vulnerability by pasting a 300-character buffer of repeated characters into the mashREPL input field, causing immediate application crash. While no public exploit is available, the low barrier to entry and high CVSS score (7.5) warrant prompt patching for organizations relying on this tool for remote administration.

🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all iOS devices running WebSSH 14.16.10 across the organization
- Restrict access to mashREPL tool until patching is complete
- Implement input validation at network level if possible
- Alert users not to paste untrusted content into mashREPL fields
2. PATCHING GUIDANCE:
- Update WebSSH to version 14.16.11 or later immediately
- Prioritize patching for devices used by critical infrastructure administrators
- Test patches in non-production environment first
- Deploy patches through MDM (Mobile Device Management) if available
3. COMPENSATING CONTROLS:
- Implement network-level input filtering for SSH sessions
- Monitor for repeated application crashes on iOS devices
- Maintain alternative remote access methods during transition period
- Restrict mashREPL access to authorized personnel only
4. DETECTION RULES:
- Monitor for WebSSH application crashes in MDM logs
- Alert on repeated failed SSH connection attempts from iOS devices
- Track application version compliance across fleet
- Log any paste operations containing repetitive character sequences
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع أجهزة iOS التي تقوم بتشغيل WebSSH 14.16.10 في المنظمة
- تقييد الوصول إلى أداة mashREPL حتى اكتمال التصحيح
- تطبيق التحقق من صحة الإدخال على مستوى الشبكة إن أمكن
- تنبيه المستخدمين بعدم لصق محتوى غير موثوق به في حقول mashREPL
2. إرشادات التصحيح:
- تحديث WebSSH إلى الإصدار 14.16.11 أو أحدث فوراً
- إعطاء الأولوية لتصحيح الأجهزة التي يستخدمها مسؤولو البنية التحتية الحرجة
- اختبار التصحيحات في بيئة غير الإنتاج أولاً
- نشر التصحيحات من خلال MDM إن أمكن
3. الضوابط البديلة:
- تطبيق تصفية الإدخال على مستوى الشبكة لجلسات SSH
- مراقبة توقف تطبيق WebSSH على أجهزة iOS
- الحفاظ على طرق وصول بديلة أثناء فترة الانتقال
- تقييد الوصول إلى mashREPL للموظفين المصرح لهم فقط
4. قواعد الكشف:
- مراقبة توقف تطبيق WebSSH في سجلات MDM
- تنبيه محاولات اتصال SSH الفاشلة المتكررة من أجهزة iOS
- تتبع توافق إصدار التطبيق عبر الأسطول
- تسجيل أي عمليات لصق تحتوي على تسلسلات أحرف متكررة
