CyberRota Analysis
AI-GeneratedAn injection vulnerability exists in the virtual network driver of libvirt, allowing users with permission to define virtual networks to inject arbitrary dnsmasq configuration directives. This could lead to arbitrary command execution with root privileges, posing a risk to systems utilizing libvirt for network management. Administrators of environments using libvirt should prioritize addressing this vulnerability to mitigate potential exploitation.
Original NVD Description
An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root.
