Software version: 10.2.2
Operating system(s): Platform Independent
Reference #: 0880775
Modified date: 28 June 2019
Summary
Dojo Toolkit, used by IBM Cognos TM1, is vulnerable to cross-site scripting
(XSS) . This issue has been addressed.
A vulnerability exists where TM1 Server could allow a local user with
specialized access to exploit an unquoted Windows search path vulnerability
which could allow local users to gain privileges via a malicious "program.exe"
file. This vulnerability has been addressed.
Vulnerability Details
CVEID: CVE-2018-15494
DESCRIPTION: Dojo Toolkit is vulnerable to cross-site scripting, caused by
improper validation of user-supplied input by the DataGrid component. A remote
attacker could exploit this vulnerability to inject malicious script into a
Web page which would be executed in a victim's Web browser within the security
context of the hosting Web site, once the page is viewed. An attacker could
use this vulnerability to steal the victim's cookie-based authentication
credentials.

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
CVEID: CVE-2019-4245
DESCRIPTION: Multiple vendor applications designed for Microsoft Windows
platforms make insecure calls to the CreateProcess() and CreateProcessAsUser()
functions using unquoted Windows search paths, which could allow a local
attacker to execute arbitrary code on the system. An attacker could exploit
this vulnerability by placing malicious files on the victim's system that have
the same name as legitimate files, which would be called by one of the
affected applications allowing the attacker to execute arbitrary code on the
system with elevated privileges.
