CVE-2023-49130: Uninitialized Pointer Access Vulnerability in Solid Edge SE2023

Overview

A serious vulnerability, identified as CVE-2023-49130, has been discovered in Solid Edge SE2023, a popular 3D CAD software. This vulnerability impacts all versions of the software prior to V223.0 Update 10. The vulnerability pertains to uninitialized pointer access when parsing specially crafted PAR files. An attacker can exploit this weakness to execute malicious code in the context of the current process. Given the widespread use of Solid Edge SE2023 in various industries, this vulnerability is of significant concern as it could lead to potential system compromise or data leakage.

Solid Edge SE2023 | All versions < V223.0 Update 10 How the Exploit Works

This exploit takes advantage of an uninitialized pointer reference within the Solid Edge SE2023 software when parsing PAR files. An attacker can craft a malicious PAR file that, when processed by the application, triggers the vulnerability and allows the execution of arbitrary code. This code runs in the context of the current process, enabling the attacker to potentially compromise the system or leak data.

Conceptual Example Code

Here is a conceptual representation of a crafted malicious PAR file that could be used to exploit this vulnerability:

# Crafted malicious PAR file
$ echo 'malicious_code_here' > exploit.par
# Use the crafted file with the vulnerable application
$ solid_edge_se2023 exploit.par

This pseudocode example shows how an attacker could inject malicious code into a PAR file, which then gets executed when the vulnerable application processes the file.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor’s patch by updating to Solid Edge SE2023 version V223.0 Update 10 or later. As a temporary mitigation, users can also use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. It’s important to note that these are only temporary measures and cannot replace the need for applying the vendor’s patch.
