1) Buffer overflow
Severity: Medium
CVSSv3:
5 [CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C] [PCI]
CVE-ID:
CVE-2020-12038
CWE-ID:
CWE-119 – Improper Restriction of Operations within the Bounds of a Memory Buffer
Exploit availability:
No
Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the algorithm that matches square brackets in the EDS subsystem. A remote authenticated attacker can create a specially crafted EDS file, trick the victim into opening it, trigger memory corruption and cause a denial of service condition on the target system.
Mitigation
Install updates from vendor’s website.

2) SQL injection
Severity: Low
CVSSv3:
6.2 [CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H/E:U/RL:O/RC:C] [PCI]
CVE-ID:
CVE-2020-12034
CWE-ID:
CWE-89 – Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)
Exploit availability:
No
Description
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker on the local network can send a specially crafted EDS file to the affected application and manipulate the database storing the EDS files, leading to denial-of-service conditions.
Mitigation
Install updates from vendor’s website.
