CVE-2019-1702    

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 
    Multiple vulnerabilities in the web-based management interface of Cisco
    Enterprise Chat and Email could allow an unauthenticated, remote attacker
    to conduct a cross-site scripting (XSS) attack against a user of the
    web-based management interface of the affected software.

    The vulnerabilities are due to insufficient validation of user-supplied
    input by the web-based management interface of the affected software. An
    attacker could exploit these vulnerabilities either by injecting malicious
    code in a chat window or by sending a crafted link to a user of the
    interface. In both cases, the attacker must persuade the user to click the
    crafted link or open the chat window that contains the attacker's code. A
    successful exploit could allow the attacker to execute arbitrary script
    code in the context of the affected interface or access sensitive,
    browser-based information.

    There are no workarounds that address these vulnerabilities.
