CVE-2022-41018: CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in Siretta QUARTZ-GOLD
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) localip A.B.C.D' command template.
AI Analysis
Technical Summary
CVE-2022-41018 is a high-severity stack-based buffer overflow vulnerability identified in the Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 device, specifically within the DetranCLI command parsing functionality. The vulnerability arises from improper bounds checking during the processing of a particular command template related to VPN basic protocols (L2TP/PPTP). The vulnerable command involves parameters such as server, username, password, firewall settings, defroute options, and local IP addresses. An attacker can exploit this flaw by sending specially crafted network packets containing malicious command sequences that overflow the stack buffer, leading to arbitrary command execution on the affected device. This vulnerability requires the attacker to have high privileges (PR:H) but does not require user interaction (UI:N). The attack vector is network-based (AV:N), and the vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported in the wild, the potential for remote code execution makes this a critical concern for organizations using the affected Siretta QUARTZ-GOLD devices. The vulnerability is classified under CWE-120, which corresponds to classic buffer overflow issues caused by copying data without proper size validation.
Potential Impact
For European organizations, the exploitation of CVE-2022-41018 could have severe consequences. Siretta QUARTZ-GOLD devices are typically used in specialized network infrastructure, including industrial, telecommunications, and critical infrastructure environments. Successful exploitation could allow attackers to execute arbitrary commands remotely, potentially leading to full device compromise. This could result in unauthorized access to sensitive network segments, disruption of network services, interception or manipulation of data, and lateral movement within organizational networks. Given the high impact on confidentiality, integrity, and availability, critical sectors such as energy, manufacturing, transportation, and government agencies in Europe could face operational disruptions, data breaches, and increased risk of espionage or sabotage. The requirement for high privileges to exploit the vulnerability suggests that attackers may need to have some level of access or insider capabilities, but once achieved, the impact could be devastating.
Mitigation Recommendations
To mitigate this vulnerability effectively, European organizations should: 1) Immediately identify and inventory all Siretta QUARTZ-GOLD devices running the affected version G5.0.1.5-210720-141020. 2) Contact Siretta for official patches or firmware updates addressing CVE-2022-41018; if unavailable, request guidance or workarounds. 3) Restrict network access to management interfaces of QUARTZ-GOLD devices using network segmentation and firewall rules, limiting exposure to trusted administrators only. 4) Implement strict access controls and multi-factor authentication to reduce the risk of privilege escalation that could enable exploitation. 5) Monitor network traffic for anomalous command sequences or unexpected packets targeting the DetranCLI interface. 6) Employ intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect attempts to exploit this buffer overflow. 7) Conduct regular security audits and penetration tests focusing on network devices to identify and remediate similar vulnerabilities proactively. 8) Develop incident response plans specific to network device compromise to minimize downtime and data loss in case of exploitation.
