89
FAUCET Score

CVE-2023-48022 is a critical remote code execution (RCE) vulnerability affecting Anyscale Ray versions 2.6.3 and 2.8.0, allowing unauthenticated attackers to execute arbitrary code via the job submission API. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite the vendor's stance that Ray is not intended for untrusted environments, the flaw is being actively exploited in the wild, with public exploit modules available (Metasploit, Nuclei) and significant community discussion, including reports of a "ShadowRay" botnet leveraging this vulnerability for cryptojacking.
