CVE-2023-0755 is a critical-severity Improper Validation of Array Index (CWE-129) vulnerability in Ge Digital Industrial Gateway Server. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-0755 is an improper array index validation vulnerability, tracked under CWE-129, that affects certain unspecified industrial control system products. The flaw carries a CVSS 3.1 base score of 9.8 and can cause the server to crash or permit remote arbitrary code execution.

An unauthenticated attacker can exploit the issue over the network without user interaction or credentials, resulting in complete loss of confidentiality, integrity, and availability on the affected system.

The associated CISA advisory ICSA-23-054-01 outlines mitigation steps for the impacted products. The EPSS score has remained flat at 0.0818 since disclosure, indicating no material increase in observed exploitation interest.
