IMPACT

The WSO2 servers are exposed to known vulnerabilities of Apache Tomcat versions prior to 7.0.69.

SOLUTION

Apply the following patches based on your products by following the instructions in the README file. Patches can also be downloaded from http://wso2.com/security-patch-releases/.

For some of the products, there may be two patches (kernel patch and platform patch) that need to be applied. In such situations refrain from restarting the server for each patch, rather apply both the patches and then restart the server.

If you have any questions, post them to security@wso2.com.

NOTES

If you are using newer versions of the products than the ones mentioned in the “SOLUTION” section, this vulnerability is fixed.
