CVE-2020-13386 Detail

Current Description

In SmartDraw 2020 27.0.0.0, the installer gives inherited write permissions to the Authenticated Users group on the SmartDraw 2020 installation folder. Additionally, when the product is installed, two scheduled tasks are created on the machine, SDMsgUpdate (Local) and SDMsgUpdate (TE). The scheduled tasks run in the context of the user who installed the product. Both scheduled tasks attempt to run the same binary, C:\SmartDraw 2020\Messages\SDNotify.exe. The folder Messages doesn't exist by default and (by extension) neither does SDNotify.exe. Due to the weak folder permissions, these can be created by any user. A malicious actor can therefore create a malicious SDNotify.exe binary, and have it automatically run, whenever the user who installed the product logs on to the machine. The malicious SDNotify.exe could, for example, create a new local administrator account on the machine.

Severity



CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  7.3 HIGH
Vector:  CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

Nist CVSS score does not match with CNA score
CNA:  MITRE
Base Score:  8.2 HIGH
Vector:  CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
