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 in Dell Secure Connect Gateway (SCG) 5.0 exposes organizations running either the Appliance (prior to 5.36.00.16) or Application (prior to 5.36.00.00) builds to unauthenticated remote exploitation via alternate XSS syntax. An attacker can bypass the product's XSS neutralization controls using non-standard or alternate encoding forms, resulting in script injection with limited confidentiality impact per the CVSS C:L assessment. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication is required and no special user interaction is necessary per the CVSS PR:N/UI:N vector - remote unauthenticated exploitation is possible against default-configuration Dell SCG 5.0 instances accessible over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.3 (Medium) appropriately reflects the limited impact ceiling - C:L/I:N/A:N - but the PR:N/AV:N/AC:L attack conditions warrant attention given the unauthenticated remote exploitation path. … 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 | Upgrade Dell SCG 5.0 Appliance to version 5.36.00.16 or later, and Dell SCG 5.0 Application to version 5.36.00.00 or later, per vendor advisory DSA-2026-382 at https://www.dell.com/support/kbdoc/en-in/000503426/dsa-2026-382-security-update-for-dell-secure-connect-gateway-virtual-edition-multiple-vulnerabilities. … Detailed patch versions, workarounds, and compensating controls in full report. |
