What is CVE-2024-1593?
CVE-2024-1593 is a high-severity path traversal vulnerability in Lfprojects Mlflow, published on 16 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A path traversal vulnerability exists in the mlflow/mlflow repository due to improper handling of URL parameters. By smuggling path traversal sequences using the ';' character in URLs, attackers can manipulate the 'params' portion of the URL to gain unauthorized access to files or directories. This vulnerability allows for arbitrary data smuggling into the 'params' part of the URL, enabling attacks similar to those described in previous reports but utilizing the ';' character for parameter smuggling. Successful exploitation could lead to unauthorized information disclosure or server compromise.
Weakness: CWE-22
