RV110W Wireless-N VPN Firewall: 1.2.1.7
RV130W Wireless-N Multifunction VPN Router: 1.0.3.8
External linksQ & 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.
2) Path traversal
EUVDB-ID: #VU14662
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0426
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router due to improper validation of directory traversal character sequences. A remote attacker can send malicious requests to the targeted device, conduct path traversal attack and gain access to arbitrary files on the affected device.
MitigationUpdate Cisco RV130W Wireless-N Multifunction VPN Router to version 1.3.0.44.
For the Cisco RV110W Wireless-N VPN Firewall and the Cisco RV215W Wireless-N VPN Router, Cisco has not released and will not release firmware updates.
Vulnerable software versionsRV215W Wireless-N VPN Router: 1.3.0.8

3) Command injection
EUVDB-ID: #VU14663
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0424
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to execute arbitrary commands.
The vulnerability exists in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router due to improper validation of user-supplied input to scripts. A remote attacker can send malicious requests to inject and execute arbitrary commands with the privileges of the root user.
MitigationUpdate Cisco RV130W Wireless-N Multifunction VPN Router to version 1.3.0.44.
For the Cisco RV110W Wireless-N VPN Firewall and the Cisco RV215W Wireless-N VPN Router, Cisco has not released and will not release firmware updates.
Vulnerable software versionsRV215W Wireless-N VPN Router: 1.3.0.8
RV110W Wireless-N VPN Firewall: 1.2.1.7

No. We are not aware of malware exploiting this vulnerability.
4) Buffer overflow
EUVDB-ID: #VU14664
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0423
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.
The vulnerability exists in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router due to boundary error when handling user-supplied input in the Guest user feature. A remote attacker can send malicious requests to a targeted device, trigger a buffer overflow condition and cause the device to stop responding or execute arbitrary code with elevated privileges.
