Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU28130
Risk: Medium
CVSSv3.1: 5 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-12038
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's website.
Vulnerable software versionsEDS Subsystem: 28.0.1
RSLinx Classic: 4.11.00
FactoryTalk Linx: 6.00 - 6.11
RSNetWorx software: 28.00.00
Studio 5000 Logix Designer: 32

2) SQL injection
EUVDB-ID: #VU28131
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-12034
CWE-ID:
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Exploit availability: No
DescriptionThe 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.
