CRITICALCVE-2019-0195 is a CRITICAL (CVSS 9.8) deserialization of untrusted data vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Tapestry core libraries in the Maven ecosystem. The issue involves deserialization of untrusted data in apache tapestry. Remediation is available by upgrading affected packages to version 5.4.5.
CVE-2019-0195 at a Glance
Security Impact
CVSS: 9.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2019-0195
To remediate this vulnerability, upgrade all affected Tapestry core 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>org.apache.tapestry</groupId>
<artifactId>tapestry-core</artifactId>
<version>5.4.5</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.tapestryHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2019-0195, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.tapestryAnalyze the terminal output to locate any version of Tapestry core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.4.5), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.tapestry 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. In Tapestry core, software state validation or input boundaries are circumvented during processing.
