DescriptionCVE.org
AMI’s SPx contains a vulnerability in the BMC where an Attacker may cause a stack-based buffer overflow via an adjacent network. A successful exploitation of this vulnerability may lead to a loss of confidentiality, integrity, and/or availability.
Executive ViewAI
CVE-2023-3043 presents critical security risk, a stack-based buffer overflow vulnerability rated CVSS 9.6. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
