Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU28995
Risk: Medium
CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-11999
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to an exposed API call allows users to provide files to be processed without sanitation. A remote authenticated attacker can specify a filename to execute arbitrary code and modify files or data.
The following products that utilize FactoryTalk Linx Software are affected:
Install updates from vendor's website.
Vulnerable software versionsFactoryTalk Linx: 6.00 - 6.11
RSLinx Classic: 4.11.00

EUVDB-ID: #VU28996
Risk: Medium
CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-12001
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to the parsing mechanism that processes certain file types does not provide input sanitation. A remote authenticated attacker can use specially crafted files to traverse the file system and modify or expose sensitive data or execute arbitrary code.
The following products that utilize FactoryTalk Linx Software are affected:
