Cisco Small Business RV320 and RV325 Routers Online Help Reflected Cross-Site
Scripting Vulnerability
Priority: Medium
Advisory ID: cisco-sa-20190404-rv-xss
First Published: 2019 April 4 14:00 GMT
Version 1.0: Final
Workarounds: No workarounds availableCisco Bug IDs: CSCvp09589
CVE-2019-1827
CWE-79
CVSS Score:
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X
Summary
o 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.
There are no workarounds that address this vulnerability.

CWE-327
CVSS Score:
5.9 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:X/RL:X/RC:X
Summary
o 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.
There are no workarounds that address this vulnerability.
