How the Exploit Works
The vulnerability arises in Premiere Pro due to a Use After Free (UAF) condition. This happens when the software continues to use memory after it has been freed, leading to a state where an attacker can exploit this condition to execute arbitrary code in the context of the current user. The exploitation of this vulnerability requires user interaction, such as opening a malicious file.
Conceptual Example Code
The following is a conceptual example demonstrating how the vulnerability might be exploited. The attacker crafts a malicious file that, when opened in the vulnerable version of Premiere Pro, triggers the UAF condition and executes the embedded arbitrary code.
class MaliciousFile:
def __init__(self):
self.payload = b"\x90" * 200 # NOP sled
self.payload += b"\xcc" # INT3 - represents malicious code
self.trigger_uaf = False
def open(self):
if self.trigger_uaf:
# Simulate UAF condition
memory = ctypes.string_at(id(self.payload), len(self.payload))
del self.payload
# The memory is now freed, but still used
execute(memory) # Arbitrary code executionThis is just a conceptual example, the actual exploit will vary based on the specific conditions of the vulnerable system.
