CVE-2025-20291


A vulnerability in Cisco Webex Meetings could have allowed an unauthenticated, remote attacker to redirect a targeted Webex Meetings user to an untrusted website. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed. This vulnerability existed because of insufficient validation of URLs that were included in a meeting-join URL. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by including a URL to a website of their choosing in a specific value of a Cisco Webex Meetings join URL. A successful exploit could have allowed the attacker to redirect a targeted user to a website that was controlled by the attacker, possibly making the user more likely to believe the website was trusted by Webex and perform additional actions as part of phishing attacks.


Security Impact Summary

This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.3, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts limited integrity, for affected systems. Impacting 1 product from cisco organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
