CVE-2023-51745: Stack Overflow Vulnerability in Various Versions of Teamcenter Visualization and JT2Go

Overview

CVE-2023-51745 is a serious cybersecurity vulnerability that has been identified in multiple versions of Teamcenter Visualization and JT2Go. This vulnerability might allow an attacker to exploit a stack overflow issue while parsing specially crafted CGM files, potentially allowing them to execute arbitrary code in the context of the current process. The potential implications of such a vulnerability are far-reaching and could include system compromise or data leakage. In a worst-case scenario, this could lead to a catastrophic breach of sensitive data and significant damage to an organization’s reputation.

Vulnerability Summary

CVE ID: CVE-2023-51745
Severity: High (7.8 CVSS Score)

Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

JT2Go | All versions < V14.3.0.6 Teamcenter Visualization V13.3 | All versions < V13.3.0.13 Teamcenter Visualization V14.1 | All versions < V14.1.0.12 Teamcenter Visualization V14.2 | All versions < V14.2.0.9 Teamcenter Visualization V14.3 | All versions < V14.3.0.6 How the Exploit Works

The exploit takes advantage of a stack overflow vulnerability in the affected applications. When these applications parse a specially crafted CGM file, an overflow in the memory stack can occur. This overflow can be manipulated by an attacker to execute arbitrary code within the context of the running application, potentially leading to system compromise or data leakage.

Conceptual Example Code

The following is a
conceptual
example of how this vulnerability might be exploited:

#include <stdio.h>
#include <string.h>
void vulnerable_function(char *data) {
char buffer[100];
strcpy(buffer, data); // Overflow can occur here if data is larger than buffer
}
int main(int argc, char *argv[]) {
char large_data[200] = "specially crafted cgm file content...";
vulnerable_function(large_data);
return 0;
}

In this simple example, an attacker could craft a CGM file with data that is larger than the buffer in `vulnerable_function()`. The extra data could then overwrite other parts of the stack, potentially allowing the attacker to execute arbitrary code.
