• Overview: CWE-249, previously known as "Often Misused: Path Manipulation," was deprecated due to confusion over its scope and overlap with other vulnerabilities. It originally referred to improper handling of file paths and potential buffer management issues.

• Exploitation Methods:

• Attackers could exploit this by manipulating file paths to access unauthorized files or directories.
• Common techniques include path traversal, symbolic link following, and buffer overflow exploits.

• Security Impact:

• Direct consequences include unauthorized access to sensitive files and potential data breaches.
• Potential cascading effects involve system compromise and privilege escalation.
• Business impact includes data loss, reputational damage, and financial penalties.

• Prevention Guidelines:

• Validate and sanitize all input related to file paths to ensure they do not contain malicious data.
• Implement strict access controls and use functions that safely handle file paths.
• Recommended tools and frameworks include static code analysis tools and secure coding libraries that enforce safe file handling practices.
