GHSA-3w6p-8f82-gw8r: Clickhouse jdbc bridge Using JMSAppender Vulnerability
HIGHGHSA-3w6p-8f82-gw8r is a HIGH (CVSS 8.1) using jmsappender vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Clickhouse jdbc bridge libraries in the Maven ecosystem. The issue involves using jmsappender in log4j configuration may lead to deserialization of untrusted data. Remediation is available by upgrading affected packages to version 2.0.7.

Security Impact
CVSS: 8.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix GHSA-3w6p-8f82-gw8r
To remediate this vulnerability, upgrade all affected Clickhouse jdbc bridge dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>ru.yandex.clickhouse</groupId>
<artifactId>clickhouse-jdbc-bridge</artifactId>
<version>2.0.7</version>
</dependency>
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=ru.yandex.clickhouse
How to Check if You Are Affected
To determine whether your Java application is affected by GHSA-3w6p-8f82-gw8r, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=ru.yandex.clickhouse
Analyze the terminal output to locate any version of Clickhouse jdbc bridge in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.7), your application is affected.
Note: The mvn dependency:tree -Dincludes=ru.yandex.clickhouse command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

"summary" : "Using JMSAppender in log4j configuration may lead to deserialization of untrusted data",
"details" : "### Impact\n\nClickHouse JDBC Bridge uses [slf4j-log4j12 1.7.32](https://repo1.maven.org/maven2/org/slf4j/slf4j-log4j12/1.7.32/), which depends on [log4j 1.2.17](https://repo1.maven.org/maven2/log4j/log4j/1.2.17/). It allows a remote attacker to execute code on the server, if you changed default log4j configuration by adding JMSAppender and an insecure JMS broker.\n\n### Patches\n\nThe patch version `2.0.7` removed log4j dependency by replacing `slf4j-log4j12` to `slf4j-jdk14`. Logging configuration is also changed from `log4j.properties` to `logging.properties`.\n\n### Workarounds\n\n1. Do NOT change log4j configuration to use JMSAppender along with insecure JMS broker\n2. Alternatively, you can issue below command to remove `JMSAppender.class`:\n\n```(bash)\n# install zip command if you don't have\napt-get update && apt-get install -y zip\n# remove the class\nzip -d clickhouse-jdbc-bridge*.jar ru/yandex/clickhouse/jdbcbridge/internal/log4j/net/JMSAppender.class\n```\n\n### References\n\nPlease refer to [CVE-2021-4104](https://access.redhat.com/security/cve/CVE-2021-4104) to read more.\n\n### For more information\n\nIf you have any questions or comments about this advisory, please feel free to open an issue in the repository.\n",
