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.

CVE-2019-1828    

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.
