Server-side attacks target vulnerabilities on the server, often involving code execution, data manipulation, or unauthorized access to server resources. Let’s evaluate each option:

Option A ("OS Code Injection"): This is a server-side attack where an attacker injects operating system commands (e.g., via system() calls in PHP) to execute arbitrary code on the server, such as rm -rf /.

Option B ("Cross-Site Request Forgery"): CSRF is a client-side attack where an attacker tricks a user’s browser into making an unintended request to a server where the user is authenticated (e.g., submitting a form to transfer funds). The attack exploits the client’s trust in the user’s session, not a server-side vulnerability. Thus, it is not a server-side attack.

Option C ("SQL Injection"): This is a server-side attack where an attacker injects malicious SQL code into a query (e.g., ' OR '1'='1) to manipulate the database, potentially extracting data or modifying records.

Option D ("Directory Traversal Attack"): This is a server-side attack where an attacker manipulates file paths (e.g., ../../etc/passwd) to access unauthorized files on the server outside the intended directory.

The correct answer is B, aligning with the CAP syllabus under "Client-Side vs. Server-Side Attacks" and "CSRF Prevention."References: SecOps Group CAP Documents - "CSRF Vulnerabilities," "Server-Side Attacks," and "OWASP Top 10 (A08:2021 - Software and Data Integrity Failures)" sections.

The HTTP response headers provide metadata about the server and its configuration. Let’s analyze each header and evaluate the statements:

Headers Breakdown:

Server: Microsoft-IIS/8.0: Indicates the web server is Microsoft Internet Information Services (IIS) version 8.0.

X-AspNet-Version: 2.0.50727: Indicates the application is using ASP.NET version 2.0.50727.

X-Powered-By: ASP.NET: Confirms the application framework is ASP.NET.

Other headers (e.g., Cache-Control, Content-Type, Expires) are standard and not directly relevant to the statements.

Option A ("The application is using an outdated server technology"): The Server: Microsoft-IIS/8.0 header indicates the server is running IIS 8.0, which was released in 2012 and is associated with Windows Server 2012. As of the current date (March 06, 2025), IIS 8.0 is outdated; Microsoft has released newer versions (e.g., IIS 10 with Windows Server 2016/2019). Additionally, mainstream support for Windows Server 2012 ended in October 2018, and extended support ended in October 2023, making IIS 8.0 unsupported and vulnerable to unpatched security issues. This statement is true.

Option B ("The application is disclosing the server version"): The Server: Microsoft-IIS/8.0 header explicitly discloses the server type (IIS) and version (8.0). Disclosing server version information is a security risk because attackers can use this to identify known vulnerabilities specific to that version (e.g., CVE exploits for IIS 8.0). Best practice is to suppress or obfuscate this header (e.g., Server: WebServer), so this statement is true.

Option C ("The application is disclosing the version of the framework used"): The X-AspNet-Version: 2.0.50727 header reveals the ASP.NET framework version (2.0.50727), which corresponds to .NET Framework 2.0, released in 2005. Disclosing the framework version is a security risk because attackers can target known vulnerabilities in that version (e.g., .NET Framework 2.0 is long unsupported; support ended in 2011). Best practice is to disable this header in the application configuration (e.g., in web.config for ASP.NET), so this statement is true.

Option D ("All of the above"): Since A (outdated server technology), B (disclosing server version), and C (disclosing framework version) are all true, this is the correct answer.

The correct answer is D, aligning with the CAP syllabus under "Information Disclosure" and "HTTP Header Security."References: SecOps Group CAP Documents - "Information Disclosure Prevention," "Server Hardening," and "OWASP Secure Headers Project" sections.
