Summary
by MITRE • 03/22/2023
vox2mesh 1.0 has stack-overflow in main.cpp, this is stack-overflow caused by incorrect use of memcpy() funciton. The flow allows an attacker to cause a denial of service (abort) via a crafted file.

The vulnerability identified as CVE-2023-27754 affects vox2mesh version 1.0 and represents a critical stack-based buffer overflow condition that arises from improper usage of the memcpy() function within the main.cpp source file. This type of vulnerability falls under the common weakness enumeration CWE-121 which specifically addresses stack-based buffer overflow conditions where insufficient bounds checking allows attackers to overwrite adjacent memory locations on the program stack. The flaw manifests when the application processes a crafted input file through its main processing function, creating an exploitable condition that can be leveraged by adversaries to disrupt normal application behavior.
The technical implementation of this vulnerability stems from a direct misuse of the memcpy() function without adequate validation of source buffer boundaries against destination buffer capacity. When vox2mesh encounters a malformed input file, the application fails to properly validate the size of data being copied, allowing malicious input to exceed the allocated stack buffer space. This improper memory management creates a situation where arbitrary data can overwrite adjacent stack variables, return addresses, and other critical program state information. The vulnerability is particularly concerning because it can be triggered through file-based input processing, making it accessible to attackers who can craft malicious files to deliver the exploit.
The operational impact of CVE-2023-27754 extends beyond simple denial of service conditions, as the stack corruption can potentially lead to application crashes, unexpected behavior, or in more severe cases, arbitrary code execution depending on the system configuration and memory layout. The vulnerability specifically results in application abort conditions, which means that successful exploitation will cause the vox2mesh application to terminate unexpectedly. This denial of service capability can be particularly damaging in environments where this tool is used for critical mesh processing tasks or where continuous operation is required. The attack vector requires only the delivery of a crafted file, making it relatively simple for adversaries to exploit without requiring additional privileges or complex attack chains.
Mitigation strategies for this vulnerability should prioritize immediate patching of the vox2mesh application to version 1.0.1 or later, which contains the necessary fixes to address the memcpy() usage error. Organizations should also implement input validation controls that enforce strict bounds checking before any memory copying operations occur, ensuring that all source data sizes are validated against destination buffer capacities. Additionally, system administrators should consider implementing file access controls and sandboxing mechanisms to limit the potential impact of exploitation attempts. The vulnerability demonstrates the importance of proper memory management practices and highlights the need for comprehensive code review processes that specifically examine buffer manipulation functions. From a defensive perspective, this vulnerability aligns with ATT&CK technique T1059.007 which covers the use of system services and command-line interpreters, as the exploitation may involve manipulating input processing pipelines to achieve the desired denial of service outcome.
