Insecure Default Password Initialization in Silex SD-330AC and AMC Manager

IdentifiersCVE-2026-32965CWE-1188· Initialization of a Resource with…

CVE-2026-32965 is an initialization of a resource with an insecure default vulnerability affecting Silex Technology SD-330AC and AMC Manager. When an affected device is connected to the network while still in its initial factory-default configuration, it can be configured using a null string password. The issue is therefore exposed during first-use or uninitialized deployment states, where the product permits configuration without a meaningful password being set. The vulnerability is classified as CWE-1188.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an unauthenticated remote attacker to alter device configuration when the product is deployed with factory-default settings. Available sources indicate high integrity impact and no stated confidentiality or availability impact under the CVSS assessment. In broader operational terms, this can enable device takeover or unauthorized administrative control over the affected device's configuration state.

Mitigation

If you can’t patch tonight, do this now.

As a workaround and hardening measure, set a password for the settings web interface before connecting the device to untrusted or production networks. More generally, avoid leaving affected devices in factory-default state, replace default or empty credentials immediately during provisioning, and avoid direct exposure of management interfaces to untrusted networks.

Remediation

Patch, then assume compromise.

Update affected products to the vendor-fixed versions: SD-330AC firmware version 1.50 or later and AMC Manager version 5.1.0 or later, as recommended by Silex Technology.
