📄 Description (English)
Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses java.util.Random() which is not cryptographically secure for timing attack mitigation. This vulnerability is fixed in 2.2.
🤖 AI Executive Summary
Jervis library versions prior to 2.2 use insecure java.util.Random() for cryptographic operations, creating vulnerability to timing attacks that could compromise Jenkins pipeline security. This affects organizations using Jervis for Job DSL and shared pipeline libraries. While no public exploit is available, the vulnerability enables attackers to potentially predict random values and bypass security controls. Immediate upgrade to version 2.2 or later is strongly recommended.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using Jenkins with Jervis library for CI/CD pipelines face timing attack risks, particularly in: (1) Banking sector (SAMA-regulated institutions) using Jenkins for secure deployment pipelines; (2) Government agencies (NCA oversight) managing critical infrastructure automation; (3) Telecom operators (STC, Mobily) running pipeline-based deployments; (4) Energy sector (ARAMCO, utilities) with Jenkins-based infrastructure automation. The vulnerability could allow attackers to predict random tokens used in pipeline authentication and authorization, potentially leading to unauthorized code deployment or pipeline manipulation.

🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all Jenkins instances using Jervis library by checking Jenkins plugin manager and pipeline library configurations
2. Document current Jervis version across all Jenkins environments
3. Review Jenkins audit logs for any suspicious pipeline execution patterns
Patching Guidance:
1. Upgrade Jervis library to version 2.2 or later immediately
2. Update Jenkins Job DSL plugin to latest compatible version
3. Restart Jenkins services after patching
4. Verify pipeline functionality post-upgrade with test runs
Compensating Controls (if immediate patching delayed):
1. Restrict Jenkins access to trusted networks only
2. Implement additional authentication factors for pipeline triggers
3. Monitor Jenkins audit logs for timing-based attack indicators
4. Disable unused pipeline libraries and Job DSL features
Detection Rules:
1. Monitor for repeated failed authentication attempts with timing patterns
2. Alert on unexpected pipeline executions or parameter modifications
3. Track changes to Jervis library configuration files
4. Monitor system logs for java.util.Random() usage in security contexts
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع مثيلات Jenkins التي تستخدم مكتبة Jervis من خلال فحص مدير المكونات الإضافية وتكوينات المكتبات
2. توثيق إصدار Jervis الحالي عبر جميع بيئات Jenkins
3. مراجعة سجلات تدقيق Jenkins للبحث عن أنماط تنفيذ خط أنابيب مريبة
إرشادات الترقية:
1. ترقية مكتبة Jervis إلى الإصدار 2.2 أو أحدث فوراً
2. تحديث مكون Jenkins Job DSL إلى أحدث إصدار متوافق
3. إعادة تشغيل خدمات Jenkins بعد التصحيح
4. التحقق من وظائف خط الأنابيب بعد الترقية من خلال عمليات الاختبار
عناصر التحكم التعويضية (إذا تأخر التصحيح الفوري):
1. تقييد وصول Jenkins للشبكات الموثوقة فقط
2. تنفيذ عوامل مصادقة إضافية لمشغلات خط الأنابيب
3. مراقبة سجلات تدقيق Jenkins لمؤشرات هجمات التوقيت
4. تعطيل المكتبات والميزات غير المستخدمة
قواعد الكشف:
1. مراقبة محاولات المصادقة الفاشلة المتكررة مع أنماط التوقيت
2. تنبيهات على تنفيذ خط الأنابيب غير المتوقع أو تعديلات المعاملات
3. تتبع التغييرات على ملفات تكوين مكتبة Jervis
4. مراقبة سجلات النظام لاستخدام java.util.Random() في السياقات الأمنية
