Pensar - auto fix for Unsanitized Media Name Input in CMS File Operations

[pensarapp]

Fixed an input validation vulnerability in the updateMediaNameAction function by adding several validation checks for the newName parameter:

1. Added a check to verify that newName is a non-empty string
2. Added trimming of leading/trailing whitespace
3. Added a check to ensure the name isn't empty after trimming
4. Added a maximum length validation (255 characters)
5. Added a regex pattern validation to ensure the name only contains safe characters (alphanumeric, spaces, hyphens, underscores, and periods)

These validation checks prevent potentially malicious input from reaching the cloud storage providers (AWS S3 and Cloudinary) and ensure that only safe, valid file names are processed. This addresses both improper input validation (CWE-20) and insufficient neutralization (CWE-74) vulnerabilities that were present in the original code.

More Details

Type	Identifier	Message	Severity	Link
Application	CWE-20, CWE-74	The code does not validate or sanitize the 'newName' parameter provided to updateMediaNameAction. Without proper input validation (CWE-20), an attacker could supply data that includes malicious payloads (e.g., injection attacks, path traversal if further file system interactions are added). Additionally, insufficient neutralization (CWE-74) might lead to harmful effects if the newName is reflected downstream without proper sanitization. Although the immediate risk might be contained by the abstraction of the external provider libraries, lack of validation constitutes a potential vulnerability in the application logic.	medium	Link
