| Título | https://github.com/bolo-blog/bolo-solo bolo-solo V2.6.4 Arbitrary file write |
|---|
| Descripción | A critical arbitrary file write vulnerability exists in Bolo-Solo version 2.6.4. The /import/cnblogs endpoint fails to properly validate or sanitize user-supplied filenames during blog import operations. As a result, an unauthenticated remote attacker can craft a malicious HTTP request that writes arbitrary content to any writable location on the server filesystem.
The application directly uses attacker-controlled input as part of the file path without canonicalization, validation, or restriction to a safe directory. This allows directory traversal (e.g., using sequences like ../) and ultimately enables overwriting or creating files such as web-accessible scripts (e.g., .jsp, .html, or configuration files), leading to remote code execution, data tampering, or full system compromise. |
