CWE
- CWE-77 - Improper Neutralization of Special Elements used in a Command ('Command Injection')
Summary
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level privileges to perform command injection attacks on an affected system and execute arbitrary commands as the root user.
This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user. Cisco has assigned this vulnerability a Security Impact Rating (SIR) of High, rather than Medium as the score indicates, because additional security implications could occur once the attacker has become root.

"value": "A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level privileges to perform command injection attacks on an affected system and\u0026nbsp;execute arbitrary commands as the root user.\r\n\r\nThis vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user. Cisco has assigned this vulnerability a Security Impact Rating (SIR) of High, rather than Medium as the score indicates, because additional security implications could occur once the attacker has become root."
