Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU19519
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L/E:U/RL:U/RC:C]
CVE-ID: CVE-2018-11224
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the in_table_init16 function in libavcodec/aacsbr.c. A remote attacker can perform denial of service attack.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Command injection
EUVDB-ID: #VU14301
Risk: Low
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-11229
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to command injection in Crestron Toolbox Protocol (CTP). A remote unauthenticated attacker can submit a specially crafted input and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) OS command injection
EUVDB-ID: #VU14300
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-11228
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
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. A remote unauthenticated attacker can submit a specially crafted input via a Bash shell service in Crestron Toolbox Protocol (CTP) and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
4) Privilege escalation
EUVDB-ID: #VU12975
Risk: Low
CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-1122
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to top reads its configuration file from the current working directory, without any security check, if the HOME environment variable is unset or empty. A local attacker can exploit one of several vulnerabilities in top's config_file() function, execute top in /tmp (for example) and gain elevated privileges.
