CVE-2021-1242 Detail

Current Description

A vulnerability in Cisco Webex Teams could allow an unauthenticated, remote attacker to manipulate file names within the messaging interface. The vulnerability exists because the affected software mishandles character rendering. An attacker could exploit this vulnerability by sharing a file within the application interface. A successful exploit could allow the attacker to modify how the shared file name displays within the interface, which could allow the attacker to conduct phishing or spoofing attacks.

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
