Security Bulletin


Summary

There are vulnerabilities in the OpenSSL, Query and YUI libraries used by BigFix, and a BigFix-specific vulnerability allowing unauthorized uploads. These are addressed in the BigFix Platform 9.5.12 releases.

Vulnerability Details

CVEID: CVE-2019-4013  
DESCRIPTION: IBM BigFix Platform could allow an authenticated user to upload a file to the server with elevated privileges. This could result in unauthorized execution on underlying system. 
CVSS Base Score: 9.0
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/155887 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H)

CVEID: CVE-2018-5407  
DESCRIPTION: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by execution engine sharing on Simultaneous Multithreading (SMT) architecture. By using the PortSmash new side-channel attack, an attacker could run a malicious process next to legitimate processes using the architecture’s parallel thread running capabilities to leak encrypted data from the CPU's internal processes.
CVSS Base Score: 5.1
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/152484 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2012-5883  
DESCRIPTION: Bugzilla is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Flash component infrastructure in YUI script. A remote attacker could exploit this vulnerability using attack vectors related to swfstore.swf to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base Score: 4.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/80116 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:M/Au:N/C:N/I:P/A:N)

 
CVEID: CVE-2012-6708  
DESCRIPTION: jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
CVSS Base Score: 6.1
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/138055 for more information
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)
 
CVEID: CVE-2015-9251  
DESCRIPTION: jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request is performed without the dataType option, causing text/javascript responses to be executed.
CVSS Base Score: 6.1
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/138029 for more information
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)
