CVE-2022-40985 in QUARTZ-GOLD
Summary
by MITRE • 01/27/2023
Several stack-based buffer overflow vulnerabilities exist in the DetranCLI command parsing functionality of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020. A specially-crafted network packet can lead to arbitrary command execution. An attacker can send a sequence of requests to trigger these vulnerabilities.This buffer overflow is in the function that manages the '(ddns1|ddns2) hostname WORD' command template.

The CVE-2022-40985 vulnerability represents a critical stack-based buffer overflow affecting the DetranCLI command parsing component of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 network equipment. This vulnerability resides within the command line interface functionality that processes network configuration commands, specifically targeting the handling of dynamic domain name system (DDNS) hostname parameters. The flaw manifests when the system processes the '(ddns1|ddns2) hostname WORD' command template, where the WORD parameter is not properly validated or bounded before being copied into a fixed-size stack buffer. This represents a classic buffer overflow condition that violates fundamental memory safety principles and creates a pathway for malicious code execution.
The technical exploitation of this vulnerability leverages the inherent weakness in input validation mechanisms within the DetranCLI parsing functions. When an attacker crafts a malicious network packet containing an excessively long hostname parameter within the DDNS command structure, the system fails to enforce proper bounds checking before copying the data into the vulnerable stack buffer. This overflow can overwrite adjacent memory locations including return addresses, function pointers, and local variables, potentially allowing an attacker to manipulate the program flow and execute arbitrary code with the privileges of the affected process. The vulnerability's classification aligns with CWE-121 Stack-based Buffer Overflow, which is categorized under the broader category of CWE-119 Improper Access to Memory Locations in the Common Weakness Enumeration framework.
The operational impact of this vulnerability extends beyond simple command execution, as it provides attackers with a potential foothold for more sophisticated attacks within the network infrastructure. An attacker who successfully exploits this vulnerability can gain unauthorized access to the QUARTZ-GOLD device, potentially leading to complete system compromise, data exfiltration, or network disruption. The vulnerability is particularly concerning because it can be triggered through network-based attacks without requiring physical access or authentication, making it a significant risk for organizations relying on this equipment for network management and security operations. The attack vector involves sending a sequence of specially crafted requests that exploit the command parsing functionality, which aligns with ATT&CK technique T1059.001 Command and Scripting Interpreter for executing malicious commands through the vulnerable interface.
Mitigation strategies for CVE-2022-40985 should prioritize immediate firmware updates from Siretta to address the root cause of the buffer overflow vulnerability. Organizations should also implement network segmentation and access controls to limit exposure of affected devices to untrusted networks, while monitoring for suspicious network traffic patterns that may indicate exploitation attempts. Additional defensive measures include deploying intrusion detection systems with signatures for known attack patterns targeting this vulnerability, implementing strict input validation at network boundaries, and conducting regular vulnerability assessments to identify similar weaknesses in other network infrastructure components. Network administrators should also consider disabling unnecessary command line interfaces when possible and maintain detailed logging of CLI activities to aid in forensic analysis should an attack occur. The vulnerability demonstrates the critical importance of proper input validation and memory management in embedded network devices, highlighting the need for robust security practices throughout the software development lifecycle.
