Title

Cisco Webex Meetings Suite and Cisco Webex Meetings Online Unauthenticated Meeting Join Vulnerability

Summary

A vulnerability in Cisco Webex Meetings Suite sites and Cisco Webex Meetings Online sites could allow an unauthenticated, remote attendee to join a password-protected meeting without providing the meeting password. The connection attempt must initiate from a Webex mobile application for either iOS or Android. The vulnerability is due to unintended meeting information exposure in a specific meeting join flow for mobile applications. An unauthorized attendee could exploit this vulnerability by accessing a known meeting ID or meeting URL from the mobile device’s web browser. The browser will then request to launch the device’s Webex mobile application. A successful exploit could allow the unauthorized attendee to join the password-protected meeting. The unauthorized attendee will be visible in the attendee list of the meeting as a mobile attendee. Cisco has applied updates that address this vulnerability and no user action is required. This vulnerability affects Cisco Webex Meetings Suite sites and Cisco Webex Meetings Online sites releases earlier than 39.11.5 and 40.1.3.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
