How to Fix CVE-2017-7559
To remediate this vulnerability, upgrade all affected Undertow 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>io.undertow</groupId>
<artifactId>undertow-core</artifactId>
<version>1.4.17.Final</version>
</dependency><dependency>
<groupId>io.undertow</groupId>
<artifactId>undertow-core</artifactId>
<version>1.3.31.Final</version>
</dependency><dependency>
<groupId>io.undertow</groupId>
<artifactId>undertow-core</artifactId>
<version>2.0.0.Alpha2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=io.undertowHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2017-7559, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=io.undertowAnalyze the terminal output to locate any version of Undertow core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.17.Final), your application is affected.
Note: The mvn dependency:tree -Dincludes=io.undertow 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-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'), where the product acts as an intermediary http agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed http requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination. In Undertow core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other than their own.",
