Vulnerabilities

A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Multiple Cisco WebEx Products Multiple Arbitrary Code Execution Vulnerabilities

Risk:
Medium
Date Discovered:
06 November 2019
Description:
Multiple Cisco WebEx products are prone to multiple local code-execution vulnerabilities. Successfully exploiting these issues will allow attackers to execute arbitrary code within the context of the application. These issues are being tracked by Cisco Bug IDs CSCvq32301, CSCvq36083, CSCvq36098, CSCvq84379,CSCvq84396, CSCvq84421, CSCvq84438, CSCvq86070, CSCvq86075, CSCvq86152, CSCvq86160, CSCvq86181, CSCvq86224, CSCvq86249, CSCvq86254

Recommendations
  • Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
    Restrict local access to trusted and accountable individuals only.
  • Block external access at the network boundary, unless external parties require service.
    Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
  • Implement multiple redundant layers of security.
    Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Updates are available. Please see the references or vendor advisory for more information.
