Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Improper Certificate Validation
EUVDB-ID: #VU26748
Risk: Medium
CVSSv3.1: 5 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-11580
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a man-in-the-middle (MitM) attack.
The vulnerability exists due to tncc.jar applet accept an arbitrary SSL certificate. A remote attacker can perform a MitM attack.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) OS Command Injection
EUVDB-ID: #VU26749
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-11581
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to insufficient validation of user-supplied input in doCustomRemediateInstructions methodm when the Host Checker policy is enforced. A remote attacker with ability to perform MitM attack (see vulnerability #1) can inject and execute arbitrary OS commands on the client system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

3) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU26750
Risk: Medium
CVSSv3.1: 5 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-11582
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass security restrictions.
The vulnerability exists due to the applet in tncc.jar launches a TCP server that accepts local connections on a random port and can be reached by local HTTP clients. A remote attacker can use this issue to gather information from the system or perform further interactions with the victim's system.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
