SD-330AC and AMC Manager provided by silex technology, Inc. contain a heap-based buffer overflow vulnerability in packet data processing of sx_smpd. Processing a crafted packet may cause a temporary denial-of-service (DoS) condition.
AnalysisAI
Heap-based buffer overflow in Silex SD-330AC and AMC Manager packet processing allows remote unauthenticated attackers to trigger a temporary denial-of-service condition via crafted network packets to the sx_smpd service. CVSS score is 5.3 (moderate) with confirmed active reporting by JPCERT, though no public exploit code or CISA KEV listing is evident from available data. …

Vulnerability AssessmentAI
| Exploitation | The sx_smpd service must be network-accessible and listening on its management port. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) indicates moderate real-world risk: network-accessible, low attack complexity, no authentication required, but impact limited to availability (temporary DoS). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on the network crafts a malicious packet conforming to the sx_smpd protocol and sends it to the SD-330AC or AMC Manager management interface without authentication. The packet triggers the heap buffer overflow in packet data processing, corrupting heap memory and causing the sx_smpd process to crash. … |
| Remediation | Contact Silex Technology, Inc. … Detailed patch versions, workarounds, and compensating controls in full report. |
