Last modified

CVE-2019-1883 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. A vulnerability in the command-line interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker with read-only credentials to inject arbitrary commands that could allow them to obtain root privileges. The vulnerability is due to insufficient validation of user-supplied input on the command-line interface. EPSS estimates a 0.41% chance of exploitation in the next 30 days.

Description

A vulnerability in the command-line interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker with read-only credentials to inject arbitrary commands that could allow them to obtain root privileges. The vulnerability is due to insufficient validation of user-supplied input on the command-line interface. An attacker could exploit this vulnerability by authenticating with read-only privileges via the CLI of an affected device and submitting crafted input to the affected commands. A successful exploit could allow an attacker to execute arbitrary commands on the device with root privileges.
