HighCVSS 8.8Exploitation Probability (EPSS)
Elevated risk54th percentile - higher than 54% of all known CVEs
Summary
A vulnerability in the web-based management interface of Cisco IMC allows an authenticated remote attacker with low privileges to execute arbitrary commands on the underlying operating system and elevate privileges to root. The issue is due to improper validation of user-supplied input.
Risk Assessment
An attacker can gain full control of the system, potentially leading to compromise of confidentiality, integrity, and availability of data and the entire infrastructure.
Recommendation
Apply Cisco IMC updates that address this vulnerability, and restrict access to the management interface to trusted users only.

See all- CVE-2026-20097Medium
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with admin-level privileges to execute arbitrary code as the root user. This is due to improper validation of user-supplied input to the management interface. An attacker could exploit this by sending crafted HTTP requests to an affected device, leading to arbitrary code execution as root. Cisco has assigned a Security Impact Rating of High due to additional security implications after gaining root access.

Vulnerability in the web-based management interface of Cisco IMC allows an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. Due to insufficient input validation. Attacker can persuade a user to click a crafted link, leading to arbitrary script execution in the browser or access to sensitive information.
- CVE-2026-20089Medium
Vulnerability in the web-based management interface of Cisco IMC allows an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. Due to insufficient input validation. Attacker can persuade a user to click a crafted link, leading to arbitrary script execution in the browser or access to sensitive information.
- CVE-2026-20088Medium
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This is due to insufficient validation of user input. An attacker could exploit this by persuading a user to click a crafted link, potentially allowing arbitrary script execution in the browser or access to sensitive browser-based information.
- CVE-2026-20087Medium
Vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This is due to insufficient validation of user input. An attacker could exploit this by persuading a user to click a crafted link, allowing arbitrary script code execution in the browser or access to sensitive browser-based information.
- CVE-2026-20085Medium
Vulnerability in the web-based management interface of Cisco IMC could allow an unauthenticated, remote attacker to conduct a reflected XSS attack against a user of the interface. This is due to insufficient validation of user input. An attacker could exploit this by persuading a user to click a crafted link, allowing arbitrary script code execution in the browser or access to sensitive browser-based information.
Original NVD description (English source)
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with low privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs 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.
