Dell Client BIOS contains a Buffer Overflow vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by manipulating an SMI to cause an arbitrary write during SMM.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

Dell BIOS versions contain an Insecure Automated Optimization vulnerability. A local authenticated malicious user could exploit this vulnerability by sending malicious input via SMI to obtain arbitrary code execution during SMM.

Dell BIOS versions contain a stack-based buffer overflow vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI to bypass security checks resulting in arbitrary code execution in SMM.

Dell BIOS contains a race condition vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI in order to bypass security checks during SMM.

Dell BIOS versions contain an Improper Authentication vulnerability. A locally authenticated malicious user could potentially exploit this vulnerability by sending malicious input to an SMI in order to bypass security controls.

An attacker may use TWinSoft and a malicious source project file (TPG) to extract files on machine executing Ovarro TWinSoft, which could lead to code execution.

Ovarro TBox proprietary Modbus file access functions allow attackers to read, alter, or delete the configuration file.

The “ipk” package containing the configuration created by TWinSoft can be uploaded, extracted, and executed in Ovarro TBox, allowing malicious code execution.

Ovarro TBox TWinSoft uses the custom hardcoded user “TWinSoft” with a hardcoded key.
