SUMMARY
Symantec Network Protection products using affected versions of Apache Tomcat are susceptible to multiple security vulnerabilities. A remote attacker, with access to the management interface, can obtain sensitive information from the server, modify information associated with a different web application, execute arbitrary code, modify server behavior, perform HTTP cache poisoning, or cause denial of service.
