CVE-2022-41779 in InfraSuite Device Master
Summary
by MITRE • 11/01/2022
Delta Electronics InfraSuite Device Master versions 00.00.01a and prior deserialize network packets without proper verification. If the device connects to an attacker-controlled server, the attacker could send maliciously crafted packets that would be deserialized and executed, leading to remote code execution.

Delta Electronics InfraSuite Device Master versions 00.00.01a and earlier contain a critical deserialization vulnerability that exposes systems to remote code execution attacks. This flaw resides in the network packet processing functionality where the software fails to properly validate incoming data before attempting to deserialize it. The vulnerability represents a classic deserialization flaw that aligns with CWE-502, which specifically addresses unsafe deserialization of untrusted data. When a device connects to a malicious server, attackers can craft specially formatted network packets that exploit this weakness to execute arbitrary code on the target system.
The technical implementation of this vulnerability stems from insufficient input validation mechanisms within the network communication layer of the InfraSuite Device Master. The software processes network packets without adequate sanitization or verification checks, allowing attackers to inject malicious payloads that get deserialized and subsequently executed by the vulnerable application. This design flaw creates a direct pathway for remote attackers to gain control over affected devices, particularly when they are configured to connect to untrusted network endpoints. The vulnerability is particularly concerning because it requires minimal prerequisites for exploitation, as the device must merely establish a connection to an attacker-controlled server to be compromised.
The operational impact of CVE-2022-41779 extends beyond simple remote code execution, potentially enabling full system compromise and persistent access to affected infrastructure. Attackers could leverage this vulnerability to install backdoors, exfiltrate sensitive data, or use compromised devices as entry points for lateral movement within network environments. The risk is amplified when considering that these devices typically operate in industrial control systems and infrastructure management environments where system integrity and availability are paramount. Organizations using Delta Electronics InfraSuite Device Master products face potential disruptions to critical infrastructure operations, as successful exploitation could lead to unauthorized modifications of device configurations or complete system takeover. The vulnerability also aligns with ATT&CK technique T1210, which covers exploitation of remote services, and T1059, covering command and script injection.
Mitigation strategies for this vulnerability should focus on immediate patching of affected systems with the latest firmware releases from Delta Electronics. Organizations must also implement network segmentation to prevent unauthorized access to devices, restrict network connectivity to only trusted servers, and deploy network monitoring solutions to detect anomalous packet patterns. Additional protective measures include disabling unnecessary network services, implementing strict firewall rules, and conducting comprehensive network scans to identify all affected devices. The remediation process should also include updating network security policies to address the specific threat vector presented by this deserialization vulnerability, ensuring that all network communications are properly validated and authenticated before processing.
