{"id":"CVE-2022-23305","url":"https://www.cyber-defence.io/tools/cve/CVE-2022-23305","generatedAt":"2026-10-27T19:05:15.721Z","title":"This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed.","description":"By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default. Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.","published":"2022-01-18T16:15:08.000Z","lastModified":"2026-06-17T04:29:50.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-89"],"affected":["apache/log4j","netapp/snapmanager","broadcom/brocade sannav","qos/reload4j","oracle/advanced supply chain planning","oracle/business intelligence","oracle/business process management suite","oracle/communications eagle ftp table base retrieval","oracle/communications instant messaging server","oracle/communications messaging server","oracle/communications network integrity","oracle/communications offline mediation controller","oracle/communications unified inventory management","oracle/e-business suite cloud manager and cloud backup module","oracle/e-business suite information discovery","oracle/enterprise manager base platform","oracle/financial services revenue management and billing analytics","oracle/healthcare foundation","oracle/hyperion data relationship management","oracle/hyperion infrastructure technology","oracle/identity management suite","oracle/identity manager connector","oracle/jdeveloper","oracle/middleware common libraries and tools","oracle/mysql enterprise monitor","oracle/retail extract transform and load","oracle/tuxedo","oracle/weblogic server"],"epss":{"score":0.66537,"percentile":0.9928,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 66.5%, higher than 99% of all known CVEs.
