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 firmwall keyword WORD description (WORD|null)' command template.

The CVE-2022-40994 vulnerability represents a critical stack-based buffer overflow within the DetranCLI command parsing system of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 network security device. This flaw resides in the command processing functionality that handles the specific command template 'no firmwall keyword WORD description (WORD|null)'. The vulnerability stems from inadequate input validation and bounds checking within the parsing routine, creating a condition where maliciously crafted network packets can trigger memory corruption. The affected system processes command-line interface instructions through a vulnerable function that fails to properly validate the length of input data before copying it into fixed-size stack buffers, leading to potential stack smashing scenarios.
The technical exploitation of this vulnerability occurs through network-based attacks where an unauthenticated remote attacker can send specially crafted packets containing malformed command sequences. The buffer overflow manifests when the system attempts to parse the 'no firmwall keyword WORD description (WORD|null)' template with excessively long input values that exceed the allocated stack buffer capacity. This condition allows attackers to overwrite adjacent stack memory locations, potentially corrupting return addresses and control flow information. The vulnerability aligns with CWE-121 Stack-based Buffer Overflow, which specifically addresses buffer overflows occurring in stack memory regions. Attackers can leverage this flaw to execute arbitrary code with the privileges of the affected process, typically resulting in complete system compromise or denial of service conditions.
The operational impact of CVE-2022-40994 extends beyond simple privilege escalation to encompass full system compromise and potential lateral movement within network environments. Since the vulnerability affects a command parsing function, successful exploitation could enable attackers to modify firewall rules, disable security features, or establish persistent backdoors within the network infrastructure. The QUARTZ-GOLD G5.0.1.5-210720-141020 device operates in network security contexts where such vulnerabilities can have cascading effects on network availability and integrity. Organizations relying on this equipment face significant risk of unauthorized access to protected network segments, data exfiltration, and potential use as a pivot point for attacking other networked systems. The vulnerability's remote exploitability without authentication makes it particularly dangerous in environments where network security devices are exposed to untrusted network traffic.
Mitigation strategies for CVE-2022-40994 should prioritize immediate firmware updates from Siretta to address the identified buffer overflow conditions. Network administrators should implement network segmentation and access controls to limit exposure of affected devices to untrusted traffic. The implementation of intrusion detection systems can help identify exploitation attempts through anomalous command parsing patterns. Security monitoring should focus on detecting unusual command sequences or malformed network packets targeting the specific command template. Organizations should also consider disabling unnecessary CLI access and implementing secure configuration practices for the QUARTZ-GOLD devices. From an ATT&CK framework perspective, this vulnerability maps to T1059.005 Command and Scripting Interpreter and T1566.001 Phishing, as exploitation typically requires network-based delivery of malicious payloads. The vulnerability also relates to T1071.004 Application Layer Protocol DNS and T1046 Network Service Scanning, as attackers may probe affected systems before exploitation. Regular vulnerability assessments and network monitoring are essential to detect and remediate similar issues in network infrastructure devices.
