    Cisco IMC Command Injection Vulnerability Alert

    Date: April 17, 2024
    CVE: CVE-2024-20356
    Vulnerability Type: Command Injection
    CWE: [[CWE-78]]
    Sources: Cisco Security Advisory

    Issue Summary

    A critical vulnerability has been identified in the Cisco Integrated Management Controller (IMC) web-based management interface. This flaw allows authenticated, remote attackers with Administrator-level privileges to perform command injection attacks, potentially gaining root access to the affected systems. Cisco has acknowledged the vulnerability and provided software updates to mitigate the issue.

    Technical Key findings

    The vulnerability results from inadequate input validation of command strings by the web-based management interface. Attackers can exploit this by sending specially crafted commands to the interface, which are then executed with elevated privileges.

    Vulnerable products

    • 5000 Series Enterprise Network Compute Systems (ENCS)
    • Catalyst 8300 Series Edge uCPE
    • UCS C-Series M5, M6, and M7 Rack Servers (standalone mode)
    • UCS E-Series Servers
    • UCS S-Series Storage Servers (standalone mode)

    Impact assessment

    Successful exploitation allows attackers to elevate privileges to root, leading to full system control. This can result in unauthorized access, data leakage, and potential interruption of operations.

    Patches or workaround

    No workarounds are available. Cisco recommends updating to the latest firmware versions provided in their security advisory to address this vulnerability.
