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, Cisco Virtualized Voice Browser, and Cisco Unified CVP OpenSocial Gadget Editor Unauthenticated Access Vulnerability
A vulnerability in the web management interface of Cisco Finesse, Cisco Virtualized Voice Browser, and Cisco Unified CVP 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, CSCvw27957, CSCwk05799
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:NCisco Finesse and Cisco Unified CVP OpenSocial Gadget Editor Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco Finesse and Cisco Unified CVP 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, CSCwk05799
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
