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 'no vpn basic protocol (l2tp|pptp) name WORD server WORD username WORD passsword WORD firmwall (on|off) defroute (on|off)' command template.

The CVE-2022-41016 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 security appliances. This vulnerability resides within the command line interface functionality that processes administrative commands, specifically targeting the parsing of network configuration parameters including vpn protocols, server specifications, and authentication credentials. The flaw manifests when the system processes the 'no vpn basic protocol (l2tp|pptp) name WORD server WORD username WORD passsword WORD firmwall (on|off) defroute (on|off)' command template, where the input validation mechanism fails to properly constrain string length during command parameter processing. The vulnerability is classified under CWE-121 as a stack-based buffer overflow, where insufficient bounds checking allows an attacker to overwrite adjacent memory locations on the stack. This particular implementation flaw affects the DetranCLI component which is responsible for processing administrative commands through a network interface, making it accessible to remote attackers who can exploit the vulnerability without requiring local access or authentication.
The operational impact of this vulnerability extends beyond simple command execution as it enables arbitrary code execution on the affected system, potentially allowing attackers to gain complete control over the network appliance. The attack vector requires only the ability to send specially crafted network packets to the targeted device, making it particularly dangerous in network environments where administrative interfaces are accessible from untrusted networks. When exploited, the buffer overflow can overwrite return addresses, function pointers, and other critical stack variables, potentially enabling attackers to inject and execute malicious code with the privileges of the DetranCLI process. The vulnerability affects the specific command parsing functionality that handles L2TP and PPTP VPN configuration parameters, where the system fails to validate the length of user-provided strings before copying them into fixed-size buffers. This allows attackers to craft payloads that exceed the allocated buffer space and overwrite adjacent memory, potentially leading to privilege escalation or complete system compromise. The vulnerability's exploitation capability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, and T1068 for exploit for privilege escalation, as the successful exploitation could provide attackers with elevated system privileges.
Mitigation strategies for CVE-2022-41016 should prioritize immediate patching from Siretta, as the vendor has likely released firmware updates addressing the buffer overflow conditions. Network segmentation and access control measures should be implemented to restrict access to the administrative interfaces, ensuring that only trusted administrative networks can reach the vulnerable command parsing functionality. The implementation of network access control lists and firewall rules can help limit exposure by blocking unauthorized access to the specific ports and protocols used by DetranCLI. Additionally, monitoring and logging should be enhanced to detect unusual command sequences or parameter combinations that might indicate exploitation attempts. The vulnerability demonstrates the importance of input validation and bounds checking in network security appliances, as highlighted in industry best practices for secure coding standards. Organizations should implement regular security assessments of their network infrastructure to identify similar buffer overflow vulnerabilities in other components, particularly those handling user input through command line interfaces. Network administrators should also consider implementing intrusion detection systems that can identify and alert on suspicious command sequences that attempt to exploit similar buffer overflow conditions, as this vulnerability represents a common attack pattern that can be detected through behavioral analysis of network traffic patterns. The affected system's exposure to remote code execution through this command parsing vulnerability underscores the critical need for maintaining up-to-date security patches and implementing defense-in-depth strategies to protect network infrastructure components from exploitation.
