CVE-2022-21626

21
FAUCET Score

CVE-2022-21626 is a vulnerability in Oracle Java SE and Oracle GraalVM Enterprise Edition, specifically affecting the Security component in versions 8u341, 8u345-perf, 11.0.16.1, 20.3.7, 21.3.3, and 22.2.0, respectively. This easily exploitable vulnerability allows an unauthenticated attacker with network access via HTTPS to cause a partial denial of service. The CVSS 3.1 Base Score is 5.3 (Medium), indicating a low impact on availability. The attack vector is network-based with low attack complexity, requiring no user interaction or privileges. It primarily impacts Java deployments running sandboxed applications or applets that load untrusted code, or can be exploited through APIs supplying data. While the potential impact is limited to partial denial of service, it's a concern for environments relying on the Java sandbox for security. Currently, there is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, suggesting low public awareness and attention to this vulnerability.
