Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Attack-Flow Graph

Executive Summary

This vulnerability is an integer overflow that leads to a heap-based buffer overflow in AnyDesk versions before 9.0.0. It occurs via a UDP packet during the processing of an Identity user image within the Discovery feature or when establishing a connection between any two clients.

Impact Analysis

The vulnerability can potentially allow an attacker to execute arbitrary code or cause a denial of service by exploiting the heap-based buffer overflow triggered by specially crafted UDP packets in AnyDesk before version 9.0.0.
