Multiple vulnerabilities in Cisco Jabber for Windows, Jabber for MacOS, and Jabber for mobile platforms could allow an attacker to execute arbitrary programs on the underlying operating system (OS) with elevated privileges or gain access to sensitive information. For more information about these vulnerabilities, see the Details section of this advisory.

Weakness

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
