DescriptionNVD

Delta Electronics AS320T has incorrect calculation of the buffer size on the stack in the GET/PUT request handler of the web service.

AnalysisAI

Remote code execution in Delta Electronics AS320T industrial automation server allows unauthenticated network attackers to trigger memory corruption via malformed GET/PUT requests to the web service. The incorrect buffer size calculation (CWE-131) enables stack-based overflow attacks against network-exposed management interfaces. …

RemediationAI

Within 24 hours: inventory all Delta AS320T deployments and document network accessibility; isolate externally-facing instances behind network segmentation or air-gapping. Within 7 days: implement network-level access controls (firewall rules) restricting web service ports to trusted administrative sources only; begin coordination with Delta for patch timeline. …
