XikeStor Layer3 switches miss authentication for downloading configuration data. Unauthenticated attacker may retrieve the configuration data containing network configurations and passwords to operate the affected product improperly or to exploit the affected product as a jump host.
AnalysisAI
Unauthenticated remote access to the configuration download function on XikeStor Layer3 switches (SKS8300-8T, SKS8300-12E2T2X, SKS8310-8X) running firmware below V1.04.B09 exposes full device configuration files to any network-reachable attacker. Recovered configurations contain network topology details and credentials, enabling attackers to authenticate to the switch itself or leverage it as a pivot point into the protected network segment it manages. …

Vulnerability AssessmentAI
| Exploitation | No authentication or special privilege is required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) correctly captures the core risk: zero-friction remote exploitation with high confidentiality impact. … 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 affected switches to firmware V1.04.B09 or later, as confirmed by the vendor advisory at https://www.xikestor.com/security-advisory/ and JPCERT/CC publication JVN#45281119. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all XikeStor SKS8300-8T, SKS8300-12E2T2X, and SKS8310-8X switches and verify firmware versions; immediately implement firewall rules to restrict network access to management and configuration ports from untrusted segments. …
