CVE-2023-48023 is a critical vulnerability that affects Anyscale Ray versions 2.6.3 and 2.8.0, allowing for server-side request forgery (SSRF) through the /log_proxy endpoint. This vulnerability poses a significant risk to organizations, as it can be exploited to access sensitive internal resources beyond the intended network boundaries. The CVSS score for this vulnerability is 9.1, indicating a critical severity level that organizations must take seriously.
The urgency for defenders cannot be understated. Risk to organizations includes potential unauthorized access to sensitive data, which may lead to further exploitation or data breaches. Organizations should prioritize patching immediately to address this vulnerability, especially if they are running affected versions in their environments.
Although the vendor has stated that Ray is not intended for use outside of a strictly controlled network environment, the presence of this vulnerability means that organizations using it must ensure they have appropriate security measures in place. The potential impact of a successful exploitation could be significant, encompassing both confidentiality and integrity impacts.
As of now, there are no known exploits for this vulnerability, but the risk remains high. Organizations should stay vigilant and monitor for any updates from Anyscale regarding remediation and security patches.
In summary, organizations leveraging Anyscale Ray versions 2.6.3 and 2.8.0 must act swiftly to remediate this critical SSRF vulnerability to protect their systems and sensitive data.
Vulnerability Details
The vulnerability allows for SSRF, which could enable attackers to make arbitrary requests from the server-side application. The CVSS score of 9.1 indicates that this vulnerability is critical, highlighting the urgency for organizations to address it. The affected versions are Anyscale Ray 2.6.3 and 2.8.0, with a publication date of November 28, 2023. The corresponding CWE classification for this vulnerability is CWE-918.
Technical Analysis
The root cause of CVE-2023-48023 is the improper handling of requests made to the /log_proxy endpoint, which allows SSRF attacks. The attack vector is network-based, requiring low complexity to exploit, and does not require any privileges or user interaction. The impacts on confidentiality and integrity are high, while availability is not affected.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant due to the potential for unauthorized access to internal systems and sensitive data. Organizations using Anyscale Ray in production environments should assess their exposure and prioritize remediation efforts. The blast radius potential is considerable, as successful exploitation could allow attackers to pivot to other internal systems, increasing the risk of a broader compromise. Given the CVSS score of 9.1 and the high percentile ranking of the EPSS score, organizations should address this vulnerability in their immediate patch cycle.
