| Severity: | ||
| CVE ID: | ||
| Rule Protection Details |
|---|
| Description: | A vulnerability in the Cisco Webex Teams client, formerly Cisco Spark, could allow an attacker to execute arbitrary commands on a targeted system. This vulnerability is due to unsafe search paths used by the application URI that is defined in Windows operating systems. An attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could cause the application to load libraries from the directory targeted by the URI link. The attacker could use this behavior to execute arbitrary commands on the system with the privileges of the targeted user if the attacker can place a crafted library in a directory that is accessible to the vulnerable system. | |
| Impact: | An attacker can execute arbitrary code via a successful exploit in the context of the vulnerable software. | |
| Affected OS: | Windows, Linux, FreeBSD, Solaris, Other Unix, Network Device, Mac OS, iOS, Android, Others | |
