CVE-2026-80172: CWE-345: Insufficient Verification of Data Authenticity in Dell Secure Connect Gateway 5.0 - Application
Dell Secure Connect Gateway (SCG) 5.0 Appliance and Application versions prior to 5.36.00.16 and 5.36.00.00 respectively contain a critical vulnerability involving insufficient verification of data authenticity. An unauthenticated remote attacker can exploit this flaw to repeatedly reuse captured requests to generate ADMIN access and refresh tokens without nonce validation or time limits on requests. This allows indefinite exploitation leading to full compromise. Dell recommends upgrading to fixed versions as soon as possible.
AI Analysis
Technical Summary
CVE-2026-80172 is a critical vulnerability in Dell Secure Connect Gateway 5.0 Appliance (prior to 5.36.00.16) and Application (prior to 5.36.00.00) caused by insufficient verification of data authenticity (CWE-345). The vulnerability allows an unauthenticated remote attacker to reuse captured requests indefinitely to obtain ADMIN access and refresh tokens because the system lacks nonce validation and time limits on requests. This flaw enables unauthorized access escalation and persistent administrative control.
Potential Impact
An unauthenticated attacker with remote access can exploit this vulnerability to gain unauthorized ADMIN access and refresh tokens repeatedly without restriction. This leads to full compromise of the affected system's administrative functions, posing a critical security risk with confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Dell recommends customers upgrade Dell Secure Connect Gateway Appliance to version 5.36.00.16 or later and the Application to version 5.36.00.00 or later at the earliest opportunity. Patch status is not explicitly confirmed in the advisory, but the vendor's upgrade recommendation indicates a fix is available in these versions. Until upgraded, systems remain vulnerable.
