Technical ContextAI · show details

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Dell PowerEdge 14G server BIOS versions prior to 2.18.1 and Dell Precision BIOS versions prior to 2.18.2, contain an Out of Bounds write vulnerability. A local attacker with low privileges could potentially exploit this vulnerability leading to exposure of some SMRAM stack/data/code in System Management Mode, leading to arbitrary code execution or escalation of privilege. Affected products include: Dell Poweredge R740 Firmware, Dell Poweredge R740Xd Firmware, Dell Poweredge R640 Firmware, Dell Poweredge R940 Firmware, Dell Poweredge R540 Firmware. Version information: prior to 2.18.1.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

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.

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
