Show ▼
Cisco released patches for three medium-severity vulnerabilities affecting ThousandEyes Virtual Appliance, ThousandEyes Enterprise Agent, and Nexus 3000/9000 switches, reducing exposure to remote command execution and denial of service. The bugs span multiple Cisco product lines and can let an attacker run commands with root privileges or as the node user. One of the issues can also trigger BGP peer flaps, which may disrupt routing stability. Cisco says it is not aware of exploitation in the wild for these defects.

Cisco patches ThousandEyes and Nexus vulnerabilities
Mitigation Patch UpdateCisco released patches for three medium-severity vulnerabilities affecting ThousandEyes Virtual Appliance, ThousandEyes Enterprise Agent, and Nexus 3000 and 9000 series switches. The flaws could let attackers execute commands remotely with root privileges or as the node user, and one issue could trigger BGP peer flaps that lead to a denial-of-service condition; Cisco says it is not aware of exploitation in the wild.
