There is a CSV injection vulnerability in ManageOne, iManager NetEco and iManager NetEco 6000. An attacker with high privilege may exploit this vulnerability through some operations to inject the CSV files. Due to insufficient input validation of some parameters, the attacker can exploit this vulnerability to inject CSV files to the target device. Se presenta una vulnerabilidad de inyección CSV en ManageOne, iManager NetEco e iManager NetEco 6000. Un atacante con altos privilegios puede explotar esta vulnerabilidad mediante algunas operaciones para inyectar los archivos CSV. • https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20211020-01-csv-en • CWE-1236: Improper Neutralization of Formula Elements in a CSV File •

CVSS: 7.8EPSS: 0%CPEs: 82EXPL: 1CVE-2019-14835 – kernel: vhost-net: guest to host kernel escape during migration
https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.
