NVD description

FatPipe MPVPN, WARP, and IPVPN appliances running the end-of-life firmware version 10.1.2r60p100 contain a stack-based buffer overflow in /usr/sbin/auth_user_pass. An unauthenticated remote attacker with access to the affected management interface can submit a crafted authentication request that reaches an unchecked copy into a fixed-size stack buffer, potentially allowing arbitrary code execution as root. The affected management interface is disabled by default and must be affirmatively enabled by the customer before the endpoint becomes reachable. FatPipe recommends restricting management access to trusted administrative networks and using WAN access control lists to limit access to trusted sources. Customers running the affected end-of-life firmware can contact FatPipe Support for help confirming their firmware version and upgrading to a current supported release at https://www.fatpipeinc.com/support/support, [email protected], or +1 800-724-8521 (option 3).

    تسجيل دخول واحد قد يكشف سطح هجوم أكبر مما يبدو. CVE-2026-90822 وCVE-2026-90823 هما ثغرتا RCE، وهذا يجعل التعامل معهما أولوية لفرق الأمن والتطبيقات، خصوصاً إذا كان مسار تسجيل الدخول ضمن الأنظمة المتأثرة. القيمة التقنية هنا ليست في أرقام CVE فقط، بل في فهم شروط الاستغلال، نطاق التعرض، وحدود التنفيذ عن بُعد كما يوضحها التحليل. عملياً، يجب ربط الثغرات بإدارة الأصول، مراجعة التعرض الخارجي، وتحديد أولوية التحديث أو إجراءات التخفيف بناءً على وجود المكوّن المتأثر في البيئة. One login flow can expose more attack surface than expected. CVE-2026-90822 and CVE-2026-90823 are RCE vulnerabilities, which makes them important for security, AppSec, and operations teams to triage carefully. The technical value is in understanding the exploitation conditions, affected scope, and where remote code execution becomes possible. In practice, this should be mapped against asset inventory, external exposure, and patch or mitigation priority for any affected systems. https://www.securifera.com/blog/2026/09/21/one-login-two-rces-cve-2026-90822-and-cve-2026-90823/ #RCE #CVE #AppSec

    Post summary

    The post reports two RCE CVEs (CVE-2026-90822 and CVE-2026-90823), explains their exploitation context, and urges asset mapping and patching, but provides no PoC, exploit tool, active exploitation evidence, or specific patch details.
