CVE-2026-32298 is an OS command injection vulnerability identified in the ANGEET ES3 KVM product. The root cause is improper neutralization of special elements in user-supplied input processed by the 'cfg.lua' script. This script fails to adequately sanitize variables before passing them to OS-level commands, enabling an attacker with authenticated access and high privileges to inject and execute arbitrary commands on the underlying operating system. The vulnerability is classified under CWE-78, indicating improper input validation leading to command injection. The CVSS 4.0 base score is 8.5, reflecting a high severity due to network attack vector, low attack complexity, no user interaction, and the requirement for high privileges but no additional authentication tokens. The scope is high, as successful exploitation can impact confidentiality and integrity of the system. The vulnerability affects version 0 of the product, with no patches currently available and no known exploits in the wild. The ANGEET ES3 KVM is a keyboard-video-mouse switch used to control multiple computers, often in sensitive or critical environments, making this vulnerability particularly concerning. Attackers exploiting this flaw could gain unauthorized command execution capabilities, potentially leading to data theft, system disruption, or lateral movement within networks.

The impact of CVE-2026-32298 is significant for organizations using ANGEET ES3 KVM devices, especially in environments where these KVMs manage critical infrastructure or sensitive systems. Successful exploitation allows an attacker with authenticated high privileges to execute arbitrary OS commands, compromising system confidentiality and integrity. This could lead to unauthorized data access, system manipulation, or disruption of operations. Given the KVM’s role in controlling multiple systems, attackers might pivot to other connected devices, amplifying the breach scope. The lack of user interaction and low attack complexity further increase the risk. Organizations relying on these devices for secure management could face operational downtime, data breaches, and potential regulatory consequences if exploited.

To mitigate CVE-2026-32298, organizations should: 1) Immediately restrict access to ANGEET ES3 KVM devices to trusted administrators only, enforcing strict authentication and network segmentation. 2) Monitor and audit all administrative access and command executions on these devices for suspicious activity. 3) Implement compensating controls such as application-layer firewalls or intrusion detection systems to detect anomalous command injection patterns targeting the 'cfg.lua' script. 4) Engage with ANGEET for official patches or updates and apply them promptly once available. 5) Where patching is not immediately possible, consider disabling or limiting features that process user-supplied variables in the 'cfg.lua' script or isolate the device from critical network segments. 6) Conduct thorough security reviews of all scripts and input validation mechanisms in the KVM environment to prevent similar injection flaws. 7) Educate administrators on the risks of command injection and enforce the principle of least privilege to minimize potential damage.
