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.
