Cisco: >> Webex Meetings >> 39.7.4 Security Vulnerabilities
Multiple vulnerabilities in the user interface of Cisco Webex Meetings Desktop App could allow an authenticated, remote attacker to obtain restricted information from other Webex users. These vulnerabilities are due to improper input validation of parameters returned to the application from a web site. An attacker with a valid Webex account could exploit these vulnerabilities by persuading a user to follow a URL that is designed to return malicious path parameters to the affected software. A successful exploit could allow the attacker to obtain restricted information from other Webex users.

A vulnerability in certain web pages of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to modify a web page in the context of a browser. The vulnerability is due to improper checks on parameter values within affected pages. An attacker could exploit this vulnerability by persuading a user to follow a crafted link that is designed to pass HTML code into an affected parameter. A successful exploit could allow the attacker to alter the contents of a web page to redirect the user to potentially malicious web sites, or the attacker could leverage this vulnerability to conduct further client-side attacks.

A vulnerability in the SSL implementation of the Cisco Intelligent Proximity solution could allow an unauthenticated, remote attacker to view or alter information shared on Cisco Webex video devices and Cisco collaboration endpoints if the products meet the conditions described in the Vulnerable Products section. The vulnerability is due to a lack of validation of the SSL server certificate received when establishing a connection to a Cisco Webex video device or a Cisco collaboration endpoint. An attacker could exploit this vulnerability by using man in the middle (MITM) techniques to intercept the traffic between the affected client and an endpoint, and then using a forged certificate to impersonate the endpoint. Depending on the configuration of the endpoint, an exploit could allow the attacker to view presentation content shared on it, modify any content being presented by the victim, or have access to call controls. This vulnerability does not affect cloud registered collaboration endpoints.

A vulnerability in the loading mechanism of specific dynamic link libraries in Cisco Webex Teams for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of the resources loaded by the application at run time. An attacker could exploit this vulnerability by crafting a malicious DLL file and placing it in a specific location on the targeted system. The malicious DLL file would execute when the vulnerable application is launched. A successful exploit could allow the attacker to execute arbitrary code on the target machine with the privileges of another user account.

A vulnerability in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow an unauthenticated, remote attacker to execute arbitrary code on the system of a targeted user. An attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or open the file. Successful exploitation could allow the attacker to execute arbitrary code on the user's system. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. The following client builds of Cisco WebEx Business Suite (WBS31 and WBS32), Cisco WebEx Meetings, and Cisco WebEx Meetings Server are affected: Cisco WebEx Business Suite (WBS31) client builds prior to T31.23.4, Cisco WebEx Business Suite (WBS32) client builds prior to T32.12, Cisco WebEx Meetings with client builds prior to T32.12, Cisco WebEx Meeting Server builds prior to 3.0 Patch 1. Cisco Bug IDs: CSCvh85410, CSCvh85430, CSCvh85440, CSCvh85442, CSCvh85453, CSCvh85457.
