DESCRIPTION:
Some vulnerabilities have been discovered in LINGO, which can be
exploited by malicious, local users to gain escalated privileges and
by malicious people to compromise a user's system.
1) The application loads libraries (e.g. myuser.dll) in an insecure
manner, which can be exploited to load arbitrary libraries by
tricking a user into e.g. opening a LINGO document (.ltf) located on
a remote WebDAV or SMB share.
Successful exploitation allows execution of arbitrary code.
2) The application is installed in a directory in the system root
with insecure permissions by default (granting members of the "Users"
group permissions to create files and directories). This can be
exploited to execute arbitrary code with the privileges of another
user running the application by placing e.g. a malicious library file
in the installation directory.
NOTE: This is a general problem for the majority of Windows
applications when installed outside the "Program Files" folder due to
unsafe default permissions combined with the way libraries are
located.
The vulnerabilities are confirmed in versions 11.0.1.6 and 12.0.2.20.
Other versions may also be affected.
SOLUTION:
Set secure permissions on the installation directory and do not open
untrusted files.
