CVE-2022-41000 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 'no gre index <1-8> tunnel A.B.C.D source (A.B.C.D|null) dest A.B.C.D keepalive (on|off) interval (<0-255>|null) retry (<0-255>|null) description (WORD|null)' command template.

The CVE-2022-41000 vulnerability represents a critical stack-based buffer overflow within the DetranCLI command parsing mechanism of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 network equipment. This flaw resides in the command processing functionality that handles specific tunnel configuration commands, making it particularly dangerous for network infrastructure devices that rely on CLI-based management. The vulnerability stems from insufficient input validation and bounds checking within the parsing function responsible for processing the complex command template structure that defines GRE tunnel parameters. The affected system processes commands using a format that includes index values, IP addresses, keepalive settings, retry parameters, and descriptive text fields, all of which can be manipulated to overflow the allocated stack buffer.
The technical implementation of this vulnerability demonstrates poor memory management practices where the system fails to properly validate the length of user-supplied input data before copying it into fixed-size stack buffers. When an attacker crafts malicious network packets containing oversized command parameters, the parsing function executes a buffer overflow condition that can overwrite adjacent stack memory locations. This type of vulnerability directly maps to CWE-121 Stack-based Buffer Overflow, which is classified as a high-severity weakness in the Common Weakness Enumeration catalog. The overflow occurs specifically within the command parsing routine that processes the 'no gre index <1-8> tunnel' template, where each parameter field can be manipulated to exceed the allocated buffer space.
From an operational perspective, this vulnerability presents a severe threat to network security as it allows for arbitrary code execution without requiring authentication or physical access to the device. Attackers can exploit this flaw by sending carefully crafted sequences of network requests that trigger the buffer overflow condition, potentially enabling complete system compromise. The vulnerability's impact extends beyond simple command execution to include potential privilege escalation, system instability, and data exfiltration capabilities. The attacker's ability to control the execution flow through stack corruption means they could potentially inject malicious code, modify system parameters, or establish persistent access points within the network infrastructure.
The exploitation of this vulnerability aligns with tactics described in the MITRE ATT&CK framework under the T1059.001 technique for command and scripting interpreter, specifically targeting remote command execution capabilities. Network administrators face significant operational challenges since the vulnerability can be triggered remotely over the network, making it particularly dangerous for devices that are exposed to untrusted network segments. The attack surface is further expanded by the fact that the vulnerability affects the CLI parsing functionality, which is typically accessible to network administrators but can also be exploited by malicious actors who gain access to legitimate administrative credentials or through other attack vectors that compromise network device management interfaces.
Organizations should implement immediate mitigations including firmware updates from Siretta to address the root cause of the buffer overflow vulnerability. Network segmentation and access control measures should be strengthened to limit exposure of affected devices to untrusted networks. Regular monitoring of network traffic for suspicious command patterns and implementing intrusion detection systems can help identify potential exploitation attempts. Additionally, administrators should disable unnecessary CLI access where possible and ensure that only authorized personnel have access to critical network infrastructure management functions. The vulnerability serves as a reminder of the importance of secure coding practices, particularly in network infrastructure devices where input validation and memory management are critical for maintaining system integrity and preventing unauthorized access.
