CVE-2023-6021 is a high-severity local file inclusion (LFI) vulnerability affecting Ray Project's log API endpoint. This vulnerability allows attackers to read any file on the server without authentication, posing significant risks to data confidentiality and integrity. The flaw has received a CVSS score of 7.5, indicating a high severity level, which necessitates urgent action from organizations using this software.
Risk to organizations includes unauthorized access to sensitive data, potentially leading to data breaches or data manipulation. The vulnerability was published on November 16, 2023, and has been marked as modified since then, highlighting its evolving nature and the importance of keeping abreast of updates.
Currently, there is no known public exploit for this vulnerability, however, given its nature and the high exploitability score of 3.9, attackers may leverage this flaw, making it critical for organizations to address it promptly.
Organizations should prioritize patching immediately to mitigate potential risks associated with this vulnerability. The issue is fixed in version 2.8.1 and later, and swift remediation is essential.
Vulnerability Details
The official description states that the vulnerability allows for LFI in Ray's log API endpoint. The flaw facilitates unauthorized file access, where attackers can read sensitive files stored on the server.
This vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) and CWE-29 (Path Traversal). The CVSS score of 7.5 denotes it as high-severity, with a high confidentiality impact while having no integrity or availability impact.
The affected product is Ray, and the vulnerability was disclosed on November 16, 2023. To protect against this vulnerability, it is crucial for users to upgrade to version 2.8.1 or later.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user inputs in the log API endpoint, allowing attackers to manipulate file paths. The attack vector is network-based, indicating that an attacker can exploit this vulnerability remotely without needing physical access to the server.
The attack complexity is low, as no special privileges are required, and user interaction is not necessary. Attackers can directly invoke the API to read files, leveraging the server's file system exposure. The impact on confidentiality is high, as sensitive information may be disclosed, while integrity and availability are unaffected.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is significant, particularly for organizations utilizing Ray in environments where sensitive data is stored or processed. An attacker exploiting this vulnerability could access confidential files, potentially leading to data breaches or compliance violations.
Given the high CVSS score and the vulnerability's presence in a widely used software component, organizations must treat the mitigation of this issue with high priority. The blast radius is considerable, affecting any organization using versions prior to 2.8.1, and thus requires immediate action to prevent unauthorized access.
