Security Bulletin: Multiple vulnerabilities in Apache Tomcat affect IBM UrbanCode Deploy (CVE-2015-5345, CVE-2015-5346, CVE-2015-5351)

Summary

Multiple vulnerabilities in Apache Tomcat affect IBM UrbanCode Deploy.

Vulnerability Details

CVEID: CVE-2015-5345 DESCRIPTION: Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an error when accessing a protected directory. By redirecting to the URL, an attacker could exploit this vulnerability to determine the presence of a directory.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110857 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2015-5346 DESCRIPTION: Apache Tomcat could allow a remote attacker to hijack a valid user’s session, caused by the failure to recycle the requestedSessionSSL field when recycling the Request object to use for a new request. By persuading a victim to visit a specially-crafted link and log in to the application, a remote attacker could exploit this vulnerability to hijack another user’s account and possibly launch further attacks on the system.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110854 for the current score

CVEID: CVE-2015-5351 DESCRIPTION: Apache Tomcat is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input by the index page. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to perform unauthorized actions. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.

Workarounds and Mitigations

IBM UrbanCode Deploy
You can manually upgrade Apache Tomcat to 6.0.45 on your IBM UrbanCode Deploy servers by replacing the existing JAR files in server_installation_dir/opt/tomcat/lib with all of the JAR files in the Tomcat_Archive/apache-tomcat-6.0.45/lib directory.
Additionally, the bootstrap.jar, commons-daemon.jar, and tomcat-juli.jar files in Tomcat_Archive/apache-tomcat-6.0.45/bin must be replaced with the corresponding JAR files in server_installation_dir/opt/tomcat/bin.
Downloads for Tomcat 6.0.45 can be found here.
