CVE-2023-1177 is a critical path traversal vulnerability that allows attackers to access arbitrary files on the server. This vulnerability affects the mlflow component in versions prior to 2.2.1. The CVSS score for this vulnerability is 9.3, indicating a severe risk to organizations. Attackers may leverage this vulnerability to gain unauthorized access to sensitive files, which could lead to data exposure or further attacks.
The risk to organizations includes potential unauthorized access to confidential information and system integrity issues. Given the high severity of this vulnerability, organizations should prioritize patching immediately.
As of now, there is a known exploit for this vulnerability, and public proof-of-concept (PoC) code has been made available in multiple repositories. The urgency for defenders cannot be overstated, as failure to address this vulnerability could lead to significant security breaches.
Organizations using mlflow should take immediate action to update to the latest version or implement necessary mitigations to protect against potential exploitation.
Vulnerability Details
The official description of CVE-2023-1177 states that it is a path traversal vulnerability, specifically allowing access to files via a pattern like '\..\filename' in the GitHub repository mlflow/mlflow prior to version 2.2.1.
This vulnerability has a CVSS score of 9.3, categorized as critical, with a high impact on confidentiality due to the potential exposure of sensitive information. It has been classified under CWE-22 (Path Traversal) and CWE-29 (Improper Validation of Array Index).
The vulnerability was published on March 24, 2023, and has since been modified. The attack vector is network-based, and it requires no privileges or user interaction, making it easily exploitable.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of file paths, allowing attackers to traverse the file system. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without any physical access to the server.
The attack complexity is low; no special skills or conditions are required for exploitation. Attackers do not need any privileges, and there is no user interaction required. The impacts of this vulnerability are significant, with high confidentiality impact, low integrity impact, and no availability impact.
Risk & Impact Analysis
The real-world deployment risk posed by CVE-2023-1177 is substantial. Organizations utilizing the affected versions of mlflow could face severe consequences, including data breaches and unauthorized access to critical files. The potential blast radius is extensive, as the vulnerability does not require authentication, enabling a wide range of attackers to exploit it.
Given the critical nature of this vulnerability and its high CVSS score, organizations must assess their exposure and prioritize remediation efforts. The high EPSS score indicates that this vulnerability is likely to be exploited in the wild, further emphasizing the need for immediate action.
