CVE-2021-42392

68
FAUCET Score

CVE-2021-42392 is a critical remote code execution (RCE) vulnerability in the H2 database, affecting various Debian and Oracle products utilizing H2. It stems from the JdbcUtils.getConnection method allowing attackers to supply malicious JNDI driver names and URLs, leading to RCE, notably through the H2 Console without authentication. With a CVSS score of 9.8 (CRITICAL) and an EPSS score indicating high exploitability, this vulnerability poses a severe risk due to its network-based attack vector and low complexity. While not listed on CISA's KEV catalog, its high community discussion and media coverage, often compared to Log4Shell, suggest significant awareness and potential for future exploitation, despite no public exploit intelligence like Metasploit or Nuclei.
