Summary

CVE-2024-51550 is a critical-severity Improper Validation of Specified Type of Input (CWE-1287) vulnerability in Abb Aspect-Ent-12 Firmware. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 23% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

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-2024-51550 is a data validation and sanitization vulnerability affecting ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series devices running version 3.08.02. The flaw resides in the Linux-based environment of these Aspect devices and permits injection of unvalidated and unsanitized data.

An unauthenticated attacker with network access can exploit the issue remotely to compromise confidentiality and integrity at a high level while also affecting availability to a lesser degree, as reflected in the CVSS 9.3 rating.

An ABB advisory describing the affected products and recommended actions is available at https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch. The associated EPSS score has remained low, moving only from 0.0475 currently to a peak of 0.0553.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs, which structurally prevents type-validation failures from being introduced or exploitable.
