A critical vulnerability, identified as CVE-2024-20356, has been found in Cisco's Integrated Management Controller (IMC). This flaw allows for command injection, potentially giving attackers the ability to gain root access to systems. The vulnerability is located in the web-based management interface of the IMC, which is used for remotely managing Cisco hardware. The issue arises from insufficient user input validation in the IMC interface, allowing an authenticated, remote attacker with administrative privileges to inject malicious commands.
Security researchers from Nettitude have developed a Proof of Concept (PoC) exploit, named "CISCown," to demonstrate this vulnerability. The exploit involves sending crafted commands through the web interface, enabling attackers to execute arbitrary code with root privileges on the underlying operating system of Cisco hardware. This PoC exploit is part of a toolkit developed by Nettitude and is available on GitHub. It uses parameters such as target IP, username, and password to automate the exploitation process and deploy a telnetd root shell service on compromised devices.
The release of this PoC exploit signifies a critical threat level for organizations using affected Cisco products. Gaining root access can lead to data theft, system downtime, and further network compromise. Cisco has responded by releasing software updates to address this vulnerability. It is strongly recommended that all affected organizations apply these updates immediately, as no known workaround mitigates this vulnerability.
The affected products include a range of Cisco servers and computing systems, such as the 5000 Series Enterprise Network Compute Systems (ENCS), Catalyst 8300 Series Edge uCPE, UCS C-Series M5, M6, and M7 Rack Servers in standalone mode, UCS E-Series Servers, and UCS S-Series Storage Servers. Users and administrators are advised to visit Cisco’s official security advisory page and the Nettitude GitHub repository hosting the exploitation toolkit for more detailed information and access to the updates.
@83r71n It sounds strongly lime "cron is extremely insecure as an authenticated attacker with administrative privileges can inject malicious commands"....
