How the Exploit Works

This vulnerability arises due to insecure permissions while creating temporary files in Dell SupportAssist OS Recovery. An authenticated local attacker could exploit this vulnerability by manipulating these insecurely created temporary files, leading to an elevation of privileges.
This elevation of privileges can give the attacker unauthorized access to system resources, potentially leading to full system compromise or data leakage. It’s important to note that the attacker would need to have initial access to the system and the ability to interact with the user session to exploit this vulnerability.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited in a Unix-like system.

# Assuming the attacker has access to user's session
$ cd /tmp
$ touch insecure_file # The insecurely created temporary file
$ chmod 777 insecure_file # Setting insecure permissions
$ echo "malicious code" > insecure_file
$ ./insecure_file # Running the file with escalated privileges

This simple example illustrates how an attacker could potentially exploit the insecure permissions to create and execute a malicious file, subsequently leading to the elevation of privileges.
Please note that this is a conceptual example, and the actual exploitation code will depend on the specific environment and system configurations.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Bluetooth Host | All versions prior to Patch XX.X

How the Exploit Works

The vulnerability arises from the mishandling of IOCTL commands with larger buffers in Bluetooth hosts. IOCTL, or input/output control, is a system call for device-specific I/O operations. A malicious actor could craft and send an IOCTL command with an overly large buffer that the Bluetooth host is not equipped to handle, causing memory corruption. This corruption could lead to unexpected behaviors, including system crashes, data leakage, or potentially providing an attacker with a means to execute arbitrary code.

Conceptual Example Code

Here is a conceptual example of how the exploit might be executed. Please note that this is a simplified demonstration and real-world exploitation would likely involve more complex techniques and obfuscation:

#include <sys/ioctl.h>
#include <fcntl.h>
#include <string.h>
int main() {
int fd = open("/dev/bluetooth", O_RDWR);
char buffer[1024000]; // excessively large buffer
memset(buffer, 'A', sizeof(buffer)); // fill the buffer with 'A'
ioctl(fd, BLUETOOTH_SOME_IOCTL, &buffer); // send IOCTL command with the large buffer
return 0;
}

In this example, the attacker opens the Bluetooth device and sends an IOCTL command with an excessively large buffer that causes memory corruption. The attacker could then leverage this vulnerability to compromise the system or leak data.

Mitigation

As a mitigation, users should immediately apply the vendor’s patch, which addresses this vulnerability. As a temporary measure, users could also implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and filter out malicious IOCTL calls. However, these are stopgap measures and cannot replace the need for the patch.
