Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU22417
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-16675
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted PC Worx or Config+ project file and execute arbitrary code on the target system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
Vulnerable software versionsConfig+: 1.86

2) Use-after-free
EUVDB-ID: #VU22420
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-12871
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when parsing the BCP files. A remote attacker can exchange the original PC Worx or Config+ project file with the manipulated one on the application programming workstation and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

4) Out-of-bounds read
EUVDB-ID: #VU22418
Risk: Medium
CVSSv3.1: 4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-12869
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing the BCP files. A remote attacker can exchange the original PC Worx or Config+ project file with the manipulated one on the application programming workstation, trigger out-of-bounds read error and read contents of memory on the system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
