{"id":"CVE-2022-23302","url":"https://www.cyber-defence.io/tools/cve/CVE-2022-23302","generatedAt":"2026-11-05T00:48:27.367Z","title":"JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to.","description":"JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. 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":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-502"],"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/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/tuxedo","oracle/weblogic server"],"epss":{"score":0.63841,"percentile":0.99223,"date":"2026-11-03","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 63.8%, higher than 99% of all known CVEs.
