📄 Description (English)
Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses padLeft(32, '0') when it should use padLeft(64, '0') because SHA-256 produces 32 bytes which equates to 64 hex characters. This vulnerability is fixed in 2.2.
🤖 AI Executive Summary
CVE-2025-68702 is a cryptographic weakness in Jervis library versions prior to 2.2 where SHA-256 hash padding is incorrectly implemented using 32 characters instead of 64, resulting in truncated hash representations. This vulnerability affects Jenkins pipeline automation and CI/CD environments, potentially compromising build integrity verification and artifact authentication. Organizations using Jervis in automated deployment pipelines face risks of undetected tampering with build artifacts and pipeline configurations.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations leveraging Jenkins CI/CD pipelines for critical infrastructure automation—particularly in banking (SAMA-regulated institutions), government digital transformation initiatives (NCA oversight), energy sector (ARAMCO operations), and telecommunications (STC infrastructure)—face elevated risk. The cryptographic weakness could allow attackers to forge or tamper with build artifacts, deployment configurations, and pipeline integrity checks without detection. Financial institutions and government agencies relying on Jervis for secure deployment automation are most vulnerable to supply chain attacks and unauthorized code injection.

🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Audit all Jenkins instances and CI/CD pipelines for Jervis library usage
- Identify all systems running Jervis versions prior to 2.2
- Review build artifact integrity logs for suspicious hash mismatches
- Implement additional hash verification using external tools (e.g., sha256sum verification)
2. PATCHING GUIDANCE:
- Upgrade Jervis library to version 2.2 or later immediately
- Update Jenkins plugins that depend on Jervis
- Restart Jenkins services after patching
- Verify patch installation: confirm padLeft uses 64-character padding
3. COMPENSATING CONTROLS (if immediate patching delayed):
- Implement external SHA-256 hash validation for all build artifacts
- Enable Jenkins audit logging for all pipeline executions
- Require manual code review for all deployments
- Implement GPG signing for critical artifacts
4. DETECTION RULES:
- Monitor Jenkins logs for hash validation failures
- Alert on mismatched artifact hashes (32 vs 64 character discrepancies)
- Track Jervis library version in configuration management
- Implement SIEM rules to detect unusual build artifact modifications
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تدقيق جميع مثيلات Jenkins وخطوط أنابيب CI/CD للتحقق من استخدام مكتبة Jervis
- تحديد جميع الأنظمة التي تقوم بتشغيل إصدارات Jervis السابقة للإصدار 2.2
- مراجعة سجلات سلامة قطع البناء للتحقق من عدم تطابق التجزئة المريبة
- تنفيذ التحقق من التجزئة الإضافي باستخدام أدوات خارجية
2. إرشادات الترقيع:
- ترقية مكتبة Jervis إلى الإصدار 2.2 أو أحدث فوراً
- تحديث مكونات Jenkins التي تعتمد على Jervis
- إعادة تشغيل خدمات Jenkins بعد الترقيع
- التحقق من تثبيت الترقيع: تأكيد استخدام padLeft لحشو 64 حرفاً
3. الضوابط البديلة (إذا تأخر الترقيع الفوري):
- تنفيذ التحقق من SHA-256 الخارجي لجميع قطع البناء
- تفعيل تسجيل تدقيق Jenkins لجميع عمليات خطوط الأنابيب
- طلب مراجعة يدوية للكود لجميع النشرات
- تنفيذ التوقيع بـ GPG للقطع الحرجة
4. قواعد الكشف:
- مراقبة سجلات Jenkins لفشل التحقق من التجزئة
- التنبيه على عدم تطابق التجزئة (عدم تطابق 32 مقابل 64 حرفاً)
- تتبع إصدار مكتبة Jervis في إدارة التكوين
- تنفيذ قواعد SIEM للكشف عن تعديلات قطع البناء غير العادية
