Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Path traversal
EUVDB-ID: #VU15389
Risk: Low
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:U/RC:C]
CVE-ID: CVE-2018-10822
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: Yes
Description
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The weakness exists due to path traversal in the web interface on D-Link routers. A remote attacker can send a /.. or // after “GET /uir” in an HTTP request, conduct directory traversal and gain access to important data.
NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-6190.
Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected device in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) OS command injection
EUVDB-ID: #VU15390
Risk: High
CVSSv3.1: 9.4 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2018-10823
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 authenticated attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to insufficient sanitization of user-supplied data within the chkisg.htm page Sip parameter. A remote authenticated attacker can inject and execute arbitrary code with elevated privileges.
MitigationCybersecurity Help is currently unaware of any solutions addressing the vulnerability.

3) Path traversal
EUVDB-ID: #VU15391
Risk: Low
CVSSv3.1: 9.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2018-10824
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: Yes
Description
The vulnerability allows a remote attacker to conduct directory traversal.
The weakness exists due to the administrative password is stored in plaintext in the /tmp/XXX/0 file. A remote attacker can send a /.. or // after “GET /uir” in an HTTP request, conduct directory traversal and get full router access.
