📄 Description (English)

UAC (Unix-like Artifacts Collector) before 3.3.0-rc1 contains a command injection vulnerability in the placeholder substitution and command execution pipeline where the _run_command() function passes constructed command strings directly to eval without proper sanitization. Attackers can inject shell metacharacters or command substitutions through attacker-controlled inputs including %line% values from foreach iterators and %user% / %user_home% values derived from system files to achieve arbitrary command execution with the privileges of the UAC process.

🤖 AI Executive Summary

CVE-2026-40032 is a critical command injection vulnerability in UAC (Unix-like Artifacts Collector) versions before 3.3.0-rc1 that allows arbitrary command execution through unsanitized placeholder substitution in the _run_command() function. Attackers can exploit foreach iterators and system file-derived values (%line%, %user%, %user_home%) to inject shell metacharacters and achieve code execution with UAC process privileges. With no patch currently available and no exploit publicly disclosed, organizations using UAC for forensic collection or system monitoring face immediate risk of compromise.

🤖 AI Intelligence Analysis Analyzed: Apr 27, 2026 11:01
🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using UAC for digital forensics, incident response, or system auditing face significant risk, particularly: (1) Government agencies and NCA utilizing UAC for security investigations and compliance monitoring; (2) Banking sector (SAMA-regulated institutions) employing UAC for forensic analysis and audit trails; (3) Critical infrastructure operators (ARAMCO, SEC, telecom providers like STC) using UAC for system monitoring and threat detection; (4) Healthcare organizations collecting system artifacts for compliance and breach investigation. The vulnerability is particularly dangerous in Saudi environments where UAC may be deployed across multiple systems with elevated privileges for centralized log collection and forensic analysis.

⚖️ Saudi Risk Score (AI)
8.2
/ 10.0
🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems running UAC versions prior to 3.3.0-rc1 using asset inventory and vulnerability scanning
2. Restrict network access to UAC processes and limit execution to trusted administrative accounts only
3. Disable UAC temporarily if not critical to operations until patch is available
4. Monitor UAC process execution logs for suspicious command patterns

COMPENSATING CONTROLS (until patch available):
1. Implement strict input validation on any user-supplied data that feeds into UAC placeholders (%line%, %user%, %user_home%)
2. Run UAC with minimal necessary privileges (principle of least privilege)
3. Use AppArmor or SELinux profiles to restrict UAC command execution capabilities
4. Implement command whitelisting for UAC-executed commands
5. Deploy Web Application Firewall (WAF) rules if UAC is exposed via web interface

DETECTION RULES:
1. Monitor for UAC process spawning unexpected child processes (bash, sh, cmd, powershell)
2. Alert on UAC executing commands containing shell metacharacters (|, &, ;, $(), ``, >, <)
3. Log and alert on UAC reading sensitive files (/etc/passwd, /etc/shadow, home directories)
4. Track UAC process with unusual environment variables or command-line arguments
5. Monitor for UAC writing to unexpected locations or modifying system files

PATCHING GUIDANCE:
1. Subscribe to UAC project security advisories for 3.3.0-rc1 or later release
2. Test patch in isolated lab environment before production deployment
3. Plan phased rollout across critical systems first (government, banking, infrastructure)
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل إصدارات UAC السابقة للإصدار 3.3.0-rc1 باستخدام جرد الأصول والفحص الضعيف
2. تقييد الوصول إلى الشبكة لعمليات UAC وتحديد التنفيذ للحسابات الإدارية الموثوقة فقط
3. تعطيل UAC مؤقتاً إذا لم يكن حرجاً للعمليات حتى يتوفر التصحيح
4. مراقبة سجلات تنفيذ عملية UAC للأنماط المريبة

الضوابط التعويضية (حتى يتوفر التصحيح):
1. تنفيذ التحقق الصارم من المدخلات على أي بيانات يوفرها المستخدم تغذي عناصر UAC النائبة
2. تشغيل UAC بأقل امتيازات ضرورية (مبدأ أقل امتياز)
3. استخدام ملفات تعريف AppArmor أو SELinux لتقييد قدرات تنفيذ أوامر UAC
4. تنفيذ القائمة البيضاء للأوامر لأوامر UAC المنفذة
5. نشر قواعد جدار الحماية لتطبيقات الويب (WAF) إذا كان UAC معرضاً عبر واجهة الويب

قواعد الكشف:
1. مراقبة عملية UAC التي تولد عمليات فرعية غير متوقعة
2. التنبيه على UAC تنفيذ أوامر تحتوي على أحرف shell metacharacters
3. تسجيل والتنبيه على UAC قراءة الملفات الحساسة
4. تتبع عملية UAC بمتغيرات بيئية أو حجج سطر أوامر غير عادية
5. مراقبة UAC الكتابة إلى مواقع غير متوقعة أو تعديل ملفات النظام

إرشادات التصحيح:
1. الاشتراك في تنبيهات أمان مشروع UAC للإصدار 3.3.0-rc1 أو إصدار لاحق
2. اختبار التصحيح في بيئة معملية معزولة قبل نشر الإنتاج
3. التخطيط للنشر المرحلي عبر الأنظمة الحرجة أولاً
