CWE-1125: Excessive Attack Surface

What is Excessive Attack Surface?

• Overview: Excessive Attack Surface refers to a situation where a software product exposes more input and output points than necessary, providing attackers with multiple opportunities to exploit potential vulnerabilities.

• Exploitation Methods:

• Attackers can exploit this vulnerability by identifying and targeting poorly secured or unnecessary input/output points.
• Common attack patterns include probing for unprotected APIs, abusing open ports, and exploiting misconfigured services.

• Security Impact:

• Direct consequences include unauthorized access, data breaches, and service disruptions.
• Potential cascading effects could involve lateral movement within a network or exploitation of other connected systems.
• Business impact might include financial loss, reputational damage, and legal liabilities.

• Prevention Guidelines:

• Specific code-level fixes include minimizing exposed interfaces and ensuring that only necessary input/output points are enabled.
• Security best practices involve regularly auditing and reducing the attack surface by removing or securing unused features, services, and APIs.
• Recommended tools and frameworks include using security testing tools to identify excessive exposure and applying firewalls or intrusion detection systems to monitor and control access.
