|---|---|---|---|
| 2023-03-10 | CVE-2023-26464 | Deserialization of Untrusted Data vulnerability in Apache Log4J ** UNSUPPORTED WHEN ASSIGNED ** When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. | 7.5 |
| 2022-01-18 | CVE-2022-23302 | Deserialization of Untrusted Data vulnerability in multiple products 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. | 8.8 |
| 2022-01-18 | CVE-2022-23305 | SQL Injection vulnerability in multiple products 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. | 9.8 |
| 2022-01-18 | CVE-2022-23307 | Deserialization of Untrusted Data vulnerability in multiple products CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. | 8.8 |
| 2021-06-16 | CVE-2020-9493 | Deserialization of Untrusted Data vulnerability in multiple products A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious code execution. | 9.8 |
| 2019-12-20 | CVE-2019-17571 | Deserialization of Untrusted Data vulnerability in multiple products Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. | 9.8 |
