CVE-2023-1133

CWE-502Published: March 27, 2023· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

Delta Electronics InfraSuite Device Master versions prior to 1.0.5 contain a vulnerability in which the Device-status service listens on port 10100/ UDP by default. The service accepts the unverified UDP packets and deserializes the content, which could allow an unauthenticated attacker to remotely execute arbitrary code.

Risk Analysis

The Device-status service in Delta Electronics InfraSuite Device Master improperly handles unverified UDP packets, leading to potential remote code execution. This critical vulnerability is rated 9.8 and allows unauthenticated attackers to execute arbitrary code.

No public exploit is currently known, and it is not included in the CISA KEV catalog. The vulnerability is remotely exploitable via UDP port 10100 with low attack complexity.

Recommended Action

Update to InfraSuite Device Master version 1.0.5 or later to secure the service.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-1133 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
