Adobe Dimension, a popular 3D rendering and design software, is widely used for creating photorealistic graphics, images, and scenes. However, security researchers have recently identified a vulnerability (CVE-2023-26404) in Adobe Dimension version 3.4.8 and earlier that can lead to the exposure of sensitive memory and a subsequent bypass of mitigation techniques such as Address Space Layout Randomization (ASLR).

Code Snippet:
Consider the following vulnerable code snippet that demonstrates the out-of-bounds read in Adobe Dimension:

void vulnerable_function(char* input) {
  char buffer[1024];
  int index = ;
  
  for (; input[index] != '\'; ++index) {
    buffer[index] = input[index];
  }
  buffer[index] = '\';
  
  // ... Application logic
}

In the above code snippet, the function accepts an input string without checking if the input length is within the bounds of the buffer. This can lead to an out-of-bounds read vulnerability as well as a potential information disclosure.

Exploit Details

To exploit this vulnerability, an attacker would need to create a malicious file that causes the out-of-bounds read when it is opened by a user in Adobe Dimension. This would enable the attacker to access sensitive memory content that could be used to bypass ASLR, which is crucial for exploiting other vulnerabilities.

Attacker gains access to sensitive memory content and uses it to bypass ASLR.

5. Attacker takes advantage of the bypassed ASLR to exploit other vulnerabilities and potentially compromise the system.
