Summary

CVE-2024-48839 is a critical-severity Code Injection (CWE-94) vulnerability in Abb Aspect-Ent-2 Firmware. Its CVSS base score is 9.3 (Critical).

Operationally, ranked in the top 5.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

CVE-2024-48839 is an improper input validation vulnerability that permits remote code execution and is tracked under CWE-94. It affects ABB ASPECT Enterprise v3.08.02 as well as the NEXUS Series and MATRIX Series at the same version. The issue received a CVSS v4 score of 9.3, reflecting network attack vector, low attack complexity, and no requirements for authentication or user interaction.

An unauthenticated remote attacker can send specially crafted input to trigger arbitrary code execution, resulting in high confidentiality and integrity impacts along with limited availability effects on the targeted systems. The current and peak EPSS score for the CVE is 0.1248.

An ABB advisory addressing the affected products is published at https://search.abb.com/library/Download.aspx?DocumentID=9AKK108469A7497&LanguageCode=en&DocumentPartId=&Action=Launch. No information on real-world exploitation or patches is provided in the available data.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
