Summary

  o Multiple vulnerabilities in the web-based management interface of Cisco
    Finesse could allow an unauthenticated, remote attacker to conduct a
    cross-site scripting (XSS) attack and obtain potentially confidential
    information by leveraging a flaw in the authentication mechanism.

    For more information about these vulnerabilities, see the Details section
    of this advisory.

    Cisco has released software updates that address these vulnerabilities.
    There are no workarounds that address these vulnerabilities.

    This advisory is available at the following link:

Affected Products

  o Vulnerable Products

    At the time of publication, these vulnerabilities affected Cisco Finesse
    releases earlier than Release 12.0 ES05 and Release 12.5 ES05.

    See the Details section in the bug ID(s) at the top of this advisory for
    the most complete and current information.

    Products Confirmed Not Vulnerable

    Only products listed in the Vulnerable Products section of this advisory
    are known to be affected by these vulnerabilities.

Details

  o The vulnerabilities are dependent on one another; exploitation of one of
    the vulnerabilities is required to exploit the other vulnerability.

    Details about the vulnerabilities are as follows:

    Cisco Finesse OpenSocial Gadget Editor Unauthenticated Access Vulnerability

    A vulnerability in the web management interface of Cisco Finesse could
    allow an unauthenticated, remote attacker to access the OpenSocial Gadget
    Editor without providing valid user credentials.

    The vulnerability is due to missing authentication for a specific section
    of the web-based management interface. An attacker could exploit this
    vulnerability by accessing a crafted URL. A successful exploit could allow
    the attacker to obtain access to a section of the interface, which they
    could use to obtain potentially confidential information and create
    arbitrary XML files.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

    CVE ID: CVE-2021-1246
    Bug ID(s): CSCvs52916
    Security Impact Rating (SIR): Medium
    CVSS Base Score: 6.5
    CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
   
    Cisco Finesse OpenSocial Gadget Editor Cross-Site Scripting Vulnerability

    A vulnerability in the web-based management interface of Cisco Finesse
    could allow an unauthenticated, remote attacker to conduct a cross-site
    scripting (XSS) attack against a user of the interface.

    The vulnerability exists because the web-based management interface does
    not properly validate user-supplied input. An attacker could exploit this
    vulnerability by persuading a user of the interface to click a crafted
    link. A successful exploit could allow the attacker to execute arbitrary
    script code in the context of the interface or access sensitive,
    browser-based information.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

    CVE ID: CVE-2021-1245
    Bug ID(s): CSCvs52916
    Security Impact Rating (SIR): Medium
    CVSS Base Score: 6.1
    CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
   
Workarounds

  o There are no workarounds that address these vulnerabilities.

Fixed Software

  o When considering software upgrades , customers are advised to regularly

    contain sufficient memory and confirm that current hardware and software
    configurations will continue to be supported properly by the new release.
    If the information is not clear, customers are advised to contact the Cisco
    Technical Assistance Center (TAC) or their contracted maintenance
    providers.
