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 Improper Neutralization of Alternate XSS Syntax vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to script injection.
AnalysisAI
Script injection via alternate XSS syntax affects Dell Secure Connect Gateway (SCG) 5.0 in both Appliance (prior to 5.36.00.16) and Application (prior to 5.36.00.00) editions, as disclosed in Dell advisory DSA-2026-382. An unauthenticated remote attacker exploiting CWE-87 can bypass the application's standard XSS filters using alternative injection syntax, causing malicious scripts to execute in the context of affected users' browsers and potentially enabling session hijacking or credential exfiltration. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required (PR:N per CVSS vector) and no special network protocol or application configuration is specified as a prerequisite beyond network-level access to the SCG web interface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 3.1 score of 5.3 Medium (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) warrants scrutiny on the UI:N metric: a no-user-interaction designation is atypical for XSS, which ordinarily requires a victim to interact with a crafted link (reflected XSS, UI:R) or view an injected page (stored XSS, still UI:R from the victim's perspective). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patches are available: upgrade Dell Secure Connect Gateway 5.0 Appliance to version 5.36.00.16 or later, and Dell Secure Connect Gateway 5.0 Application to version 5.36.00.00 or later, per Dell advisory DSA-2026-382 (https://www.dell.com/support/kbdoc/en-in/000503426/). … Detailed patch versions, workarounds, and compensating controls in full report. |
