A deserialization flaw was found in Apache log4j 1.2.x. While reading serialized log events, they are improperly deserialized.

Note this is the same as CVE-2020-9493 which identified a deserialization issue in Apache Chainsaw. Prior to Chainsaw V2.0, Chainsaw was a component of Apache Log4j 1.2.x.

SQL Injection
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

A flaw was found in the Java logging library Apache Log4j in version 1.x. JDBCAppender in Log4j 1.x is vulnerable to SQL injection in untrusted data. This allows a remote attacker to run SQL statements in the database if the deployed application is configured to use JDBCAppender with certain interpolation tokens.

A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSSink in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if JMSSink is deployed and has been configured to perform JNDI requests.

A flaw was found in the Java logging library Apache Log4j in version 1.x . This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender.

In 1.x you will find that there are two places where lookups are done - that is JMSAppender.java:207 and JMSAppender.java:222 - if you set TopicBindingName or TopicConnectionFactoryBindingName to something that JNDI can handle - for example "ldap://host:port/a" JNDI will do exactly the same thing it does for 2.x - so 1.x is vulnerable, just attack vector is "safer" as it depends on configuration rather than user input

This flaw in Log4j 2.x is tracked via CVE-2021-44228

Remedy

These are the possible mitigations for this flaw for releases version 1.x: - Comment out or remove JMSAppender in the Log4j configuration if it is used - Remove the JMSAppender class from the classpath. For example: ``` zip -q -d log4j-*.jar org/apache/log4j/net/JMSAppender.class ``` - Restrict access for the OS user on the platform running the application to prevent modifying the Log4j configuration by the attacker.

XSS
AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Impact Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround this issue without upgrading, use DOMPurify with its SAFEFORJQUERY option to sanitize the HTML string before passing it to a jQuery method.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle ADF Faces. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Remote Regions component. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the web server.
