🔗 NVD Official
📄 Description (English)

parseusbs before 1.9 contains an OS command injection vulnerability where the volume listing path argument (-v flag) is passed unsanitized into an os.popen() shell command with ls, allowing arbitrary command injection via crafted volume path arguments containing shell metacharacters. An attacker can provide a crafted volume path via the -v flag that injects arbitrary commands during volume content enumeration.

🤖 AI Executive Summary

CVE-2026-40030 is a critical OS command injection vulnerability in parseusbs before version 1.9 that allows arbitrary command execution through unsanitized volume path arguments passed to shell commands. The vulnerability exists in the -v flag parameter which is directly passed to os.popen() without sanitization, enabling attackers to inject shell metacharacters and execute arbitrary commands. With no patch currently available and moderate CVSS score of 7.8, this poses significant risk to organizations using parseusbs for USB device enumeration and forensic analysis.

🇸🇦 Saudi Arabia Impact Assessment
This vulnerability primarily impacts Saudi government agencies (NCA, NCSC), law enforcement, and cybersecurity firms that utilize parseusbs for digital forensics, USB device analysis, and incident response operations. Banking sector organizations (SAMA-regulated) using parseusbs in security operations centers for threat analysis face elevated risk. Healthcare institutions conducting forensic investigations and energy sector organizations (ARAMCO, SEC) performing security audits are also vulnerable. Telecommunications providers (STC, Mobily) using parseusbs in their SOCs for malware analysis and threat hunting could be compromised. The vulnerability is particularly dangerous in air-gapped forensic environments where parseusbs might be trusted without input validation.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all systems running parseusbs versions before 1.9 using asset inventory and vulnerability scanning tools
2. Restrict access to parseusbs binary to authorized personnel only through file permissions (chmod 750)
3. Disable or isolate parseusbs functionality until patching is available
4. Review audit logs for suspicious -v flag usage patterns containing shell metacharacters (|, ;, &, $, `, etc.)

COMPENSATING CONTROLS:
1. Implement input validation wrapper script that sanitizes volume path arguments before passing to parseusbs
2. Use allowlist-based validation: only permit alphanumeric characters, hyphens, underscores, and forward slashes in volume paths
3. Run parseusbs in restricted containers/sandboxes with minimal privileges and network isolation
4. Implement command-line argument logging and monitoring for suspicious patterns
5. Use SELinux or AppArmor profiles to restrict parseusbs process capabilities

DETECTION RULES:
1. Monitor process execution logs for parseusbs with -v arguments containing: pipe (|), semicolon (;), ampersand (&), backticks (`), dollar signs ($), or command substitution patterns
2. Alert on parseusbs spawning unexpected child processes (bash, sh, cmd, powershell)
3. Monitor file system access from parseusbs to sensitive directories outside expected USB mount points
4. Track network connections initiated by parseusbs or its child processes

PATCHING GUIDANCE:
1. Monitor parseusbs GitHub repository and vendor announcements for version 1.9+ release
2. Establish upgrade testing procedure in isolated lab environment before production deployment
3. Plan phased rollout of patched version across organization
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل إصدارات parseusbs قبل 1.9 باستخدام أدوات جرد الأصول والفحص
2. تقييد الوصول إلى ملف parseusbs للموظفين المصرح لهم فقط من خلال أذونات الملفات
3. تعطيل أو عزل وظيفة parseusbs حتى يتوفر التصحيح
4. مراجعة سجلات التدقيق للأنماط المريبة في استخدام العلم -v التي تحتوي على أحرف shell

الضوابط التعويضية:
1. تنفيذ سكريبت تحقق من صحة الإدخال يعقم معاملات مسار وحدة التخزين قبل التمرير إلى parseusbs
2. استخدام التحقق القائم على قائمة بيضاء: السماح فقط بالأحرف الأبجدية الرقمية والواصلات والشرطات السفلية والشرطات المائلة
3. تشغيل parseusbs في حاويات/بيئات رملية مقيدة بامتيازات دنيا وعزل الشبكة
4. تنفيذ تسجيل ومراقبة معاملات سطر الأوامر للأنماط المريبة
5. استخدام ملفات تعريف SELinux أو AppArmor لتقييد قدرات عملية parseusbs

قواعد الكشف:
1. مراقبة سجلات تنفيذ العملية لـ parseusbs مع معاملات -v تحتوي على: الأنابيب والفواصل المنقوطة والعلامات التجارية والعلامات العكسية
2. التنبيه عند قيام parseusbs بإنشاء عمليات فرعية غير متوقعة
3. مراقبة الوصول إلى نظام الملفات من parseusbs إلى الدلائل الحساسة
4. تتبع اتصالات الشبكة التي يبدأها parseusbs أو عملياته الفرعية

إرشادات التصحيح:
1. مراقبة مستودع parseusbs والإعلانات الرسمية للإصدار 1.9+
2. إنشاء إجراء اختبار الترقية في بيئة معملية معزولة
3. التخطيط لنشر متدرج للإصدار المصحح عبر المنظمة
