Final Thoughts
Vulnerabilities in Desktop Applications
Desktop applications are common targets for attackers because they often handle sensitive information, interact with system resources, and run with high privileges. Due to their complexity, a wide variety of vulnerabilities can be found in these applications, including:
Common Vulnerabilities in Desktop Apps
Code Injection & Remote Code Execution: Attackers exploit flaws to execute malicious code on the victim’s machine.
Buffer Overflows: Memory corruption vulnerabilities that can lead to crashes or arbitrary code execution.
Insecure Data Storage: Sensitive data stored insecurely, making it accessible to malicious actors.
Inadequate Authentication & Authorization: Weak access controls that can allow unauthorized users to escalate privileges.
DLL Hijacking & Insecure DLL Loading: Malicious DLL files loaded if the application doesn’t validate library paths properly.
Privilege Escalation: Exploiting vulnerabilities to gain higher system privileges.
Insecure Inter-process Communication: Flaws in communication channels that can be intercepted or manipulated.
Insecure Cryptography: Use of weak or deprecated cryptographic algorithms compromising data confidentiality.
XSS & SQL Injection: While more common in web applications, these vulnerabilities can also exist in desktop apps that embed web views or interact with databases insecurely.
