How the CVE Works
The CVE-2025-XXXXX vulnerability in files-bucket-server arises due to insufficient sanitization of user-supplied input in file path operations. Attackers can manipulate path traversal sequences (e.g., ../) to escape the restricted directory and access arbitrary files on the system. This occurs when the server fails to validate or normalize file paths before processing read/write operations. Exploiting this flaw allows unauthorized access to sensitive system files, configuration data, or application source code, depending on server permissions.
DailyCVE Form
Platform: files-bucket-server
Version: All versions
Vulnerability: Directory Traversal
Severity: High
Date: Jul 23, 2025
Prediction: Patch expected by Aug 6, 2025
What Undercode Say
curl -X GET "http://target/files-bucket-server/../../etc/passwd"
import requests
response = requests.get("http://target/files-bucket-server/%2e%2e/%2e%2e/etc/shadow")
print(response.text)
How Exploit
- Craft HTTP requests with `../` sequences.
- Use URL-encoded traversal payloads (
%2e%2e/). - Target sensitive files (e.g.,
/etc/passwd).
Protection from this CVE
- Update to patched version.
- Implement path normalization.
- Restrict file system permissions.
Impact
- Unauthorized file access.
- Data leakage.
- System compromise.
