Security Bulletin: Two (2) Vulnerabilities in Apache Tomcat affect IBM FlashSystem 840 and V840 systems (CVE-2014-0075 and CVE-2014-0099)

Summary

Apache Tomcat is used by IBM FlashSystem 840 and V840 systems. Apache Tomcat has two vulnerabilities which an attacker could exploit. One vulnerability could be exploited to deny access to the system’s Graphical User Interface (GUI) administrative interface. An attacker could exploit a second vulnerability to gain access to user credentials and use those to gain unauthorized administrative access to the system.
