1) Information disclosure

EUVDB-ID: #VU7981

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-2017-6784

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists in the web interface of the Cisco RV340, RV345, and RV345P Dual WAN Gigabit VPN Routers due to Cisco WebEx Meetings not sufficiently protecting sensitive data when responding to an HTTP request to the web interface. A remote attacker can attempt to use the HTTP protocol, read data in the HTTP responses from the Cisco WebEx Meetings Server and find sensitive information about the application.

Successful exploitation of the vulnerability may result in additional reconnaissance attacks.

Mitigation

Install update from vendor's website.
