CVE-2020-3413: Cisco Webex Meetings Scheduled Meeting Template Deletion Vulnerability

A vulnerability in the scheduled meeting template feature of Cisco Webex Meetings could allow an authenticated, remote attacker to delete a scheduled meeting template that belongs to another user in their organization. The vulnerability is due to insufficient authorization enforcement for requests to delete scheduled meeting templates. An attacker could exploit this vulnerability by sending a crafted request to the Webex Meetings interface to delete a scheduled meeting template. A successful exploit could allow the attacker to delete a scheduled meeting template that belongs to a user other than themselves.

Security readout for executives and security teams

Plain-English summary

This is a medium-severity Cisco Webex Meetings authorization flaw. A signed-in user could delete another user’s scheduled meeting template within the same organization. The direct business impact is limited integrity loss and workflow disruption, not data theft or service takeover based on the supplied sources.

Executive priority

Treat this as a moderate operational integrity issue. It is unlikely to justify emergency response by itself, but Webex administrators should confirm exposure and vendor guidance because misuse could disrupt recurring meeting workflows.

Technical view

Cisco describes insufficient authorization enforcement in the scheduled meeting template deletion feature. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, meaning network-reachable, low-complexity exploitation requiring privileges, with low integrity impact only.

Likely exposure

Exposure is limited to Cisco Webex Meetings environments where users can authenticate and use scheduled meeting templates. The sources do not identify specific affected versions, deployment models, or tenant configurations.

Exploitation context

The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. The attacker model is an authenticated remote user in the same organization, not an unauthenticated internet attacker.

Researcher notes

The evidence supports CWE-284 improper authorization with low integrity impact. The supplied data does not include affected version ranges, patch details, indicators of compromise, or exploitation in the wild, so conclusions should stay bounded to Cisco’s advisory and CVE metadata.

Mitigation direction

  • Review Cisco’s advisory for current vendor guidance and any service-side remediation details.
  • Limit Webex account access to authorized users only.
  • Review administrative controls around meeting templates and user permissions.
  • Monitor for unexplained deletion of scheduled meeting templates.

Validation and detection

  • Confirm whether Cisco Webex Meetings is in use by the organization.
  • Check whether scheduled meeting templates are used for operational meetings.
  • Review audit logs for unexpected template deletions, if available.
  • Verify Cisco advisory status and any applicable tenant or product remediation.

Improper Access Control

Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
