CVE-2024-1593
Path Traversal vulnerability in mlflow (PyPI)
What is CVE-2024-1593 About?
This vulnerability is a path traversal flaw in the mlflow/mlflow repository, enabling attackers to smuggle path traversal sequences using the ';' character in URLs. This manipulation allows for arbitrary data injection into URL parameters and unauthorized file access. Exploitation is moderately complex, requiring careful crafting of URLs to bypass existing validation mechanisms.
Affected Software
Technical Details
The vulnerability exists in the mlflow/mlflow repository due to improper handling of URL parameters, specifically regarding the use of the semicolon (;) character. Attackers can smuggle path traversal sequences (e.g., ../) within the URL's params portion by utilizing the ; character. This bypasses existing URL parameter parsing or validation mechanisms, which may incorrectly interpret the semicolon and subsequent characters within the intended parameter boundaries. This allows an attacker to inject arbitrary data, including path traversal sequences, into the params section of the URL. This can lead to unauthorized access to files or directories on the server by manipulating file paths read by the application, similar to other reported path traversal issues but with a novel semicolon-based smuggling technique.
What is the Impact of CVE-2024-1593?
Successful exploitation may allow attackers to gain unauthorized access to files or directories, disclose sensitive information, or potentially achieve server compromise through further chained attacks.
What is the Exploitability of CVE-2024-1593?
Exploitation of this vulnerability is moderately complex, as it requires careful crafting of URLs to smuggle path traversal sequences using the semicolon character. The attacker needs to understand how the application parses URL parameters and how the ';' character interacts with this parsing to inject malicious paths. There are no explicit authentication or privilege requirements mentioned, suggesting that any user capable of interacting with the MLflow web interface could potentially exploit this. This is a remote vulnerability, as it involves manipulating URLs sent to the server. The likelihood of exploitation increases if the application processes URL parameters without strong validation against path traversal characters, especially the semicolon, and if it attempts to access local files based on user-controlled input in these parameters.
