Security Bulletin: Multiple vulnerabilities in Apache Tomcat affect IBM Cognos Metrics Manager (CVE-2016-0762, CVE-2016-6816)


## Summary Vulnerabilities have been addressed in the Apache Tomcat 6 component of IBM Cognos Metrics Manager. ## Vulnerability Details **CVEID:** [_CVE-2016-0762_](<https://vulners.com/cve/CVE-2016-0762>)** DESCRIPTION:** Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by the failure to process the user supplied password if the specified user name does not exist by the Realm implementation. An attacker could exploit this vulnerability to conduct a timing attack and determine valid usernames on the system. CVSS Base Score: 5.3 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/118407_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/118407>) 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-2016-6816_](<https://vulners.com/cve/CVE-2016-6816>)** DESCRIPTION:** Apache Tomcat is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information. CVSS Base Score: 6.1 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/119158_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/119158>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) ## Affected Products and Versions * IBM Cognos Metrics Manager 10.2.2 * IBM Cognos Metrics Manager 10.2.1 * IBM Cognos Metrics Manager 10.2 * IBM Cognos Metrics Manager 10.1.1 ## Remediation/Fixes The recommended solution is to apply the fix as soon as practical. As the fix is in a shared component across the Business Intelligence portfolio, applying the BI Interim Fix will resolve the issue. Note that the prerequisites named in the links are also satisfied by an IBM Cognos Metrics Manager install of the same version. | Version| Interim Fix ---|---|--- IBM Cognos Metrics Manager| 10.2.2| [IBM Cognos Business Intelligence 10.2.2 Interim Fix 14 ](<http://www-01.ibm.com/support/docview.wss?uid=swg24043288>) IBM Cognos Metrics Manager| 10.2.1| [IBM Cognos Business Intelligence 10.2.1 Interim Fix 19](<http://www-01.ibm.com/support/docview.wss?uid=swg24043288>) IBM Cognos Metrics Manager| 10.2| [IBM Cognos Business Intelligence 10.2 Interim Fix 22](<http://www-01.ibm.com/support/docview.wss?uid=swg24043288>) IBM Cognos Metrics Manager| 10.1.1| [IBM Cognos Business Intelligence 10.1.1 Interim Fix 21](<http://www-01.ibm.com/support/docview.wss?uid=swg24043287>) ## Workarounds and Mitigations None ##
