Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, this Cisco Small Business RV Series router is affected by multiple vulnerabilities:

 - A vulnerability in the Online Help web service of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the service.The vulnerability exists because the Online Help web service of an affected device insufficiently validates user-supplied input. An attacker could exploit this vulnerability by persuading a user of the service to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected service or access sensitive browser-based information.
 (CVE-2019-1827)

 - A vulnerability in the web-based management interface of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to access administrative credentials.The vulnerability exists because affected devices use weak encryption algorithms for user credentials. An attacker could exploit this vulnerability by conducting a man-in- the-middle attack and decrypting intercepted credentials. A successful exploit could allow the attacker to gain access to an affected device with administrator privileges. (CVE-2019-1828)
