Description
Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Insufficient Verification of Data Authenticity vulnerability. An unauthenticated attacker with remote access could exploit this, leading to unauthorized access. This vulnerability is considered critical as an unauthenticated attacker can repeatedly reuse a captured request to generate ADMIN access and refresh tokens. Since there is no nonce validation or time limit on requests, the attack can be performed indefinitely. Dell recommends customers to upgrade at the earliest opportunity

AI Analysis

Impact

The vulnerability is an insufficient verification of data authenticity, allowing an attacker to capture a legitimate request and replay it repeatedly to obtain administrative access tokens. Because no nonce or time limit is enforced, the attack can be carried out indefinitely. This flaw, classified as CWE-345, could lead to full control over the Secure Connect Gateway appliance or application through unauthorized admin privileges.

Affected Systems

Dell Secure Connect Gateway 5.0 Appliance versions before 5.36.00.16 and Application versions before 5.36.00.00 are impacted.

Risk and Exploitability

The CVSS score of 9.8 indicates critical severity, yet the EPSS score is not available, so the probability of exploitation is unclear. The vulnerability is not listed in CISA KEV. Based on the description, the attack vector is remote over the network; an unauthenticated attacker can replay captured requests without any additional credentials. This scenario poses a significant risk to confidentiality and integrity of the system.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Dell Secure Connect Gateway Appliance to version 5.36.00.16 or later, and upgrade Application to version 5.36.00.00 or later.
  • Until the upgrade is applied, block or restrict external access to administrative endpoints to mitigate replay attacks.
  • Implement additional session token rotation or enforce nonce and time‑limited request validation, if supported by the system, to prevent indefinite replay exploitation.
