CVE-2023-49127: Critical Out of Bounds Read Vulnerability in Solid Edge SE2023

Overview

In today’s cybersecurity landscape, vulnerabilities are discovered daily that could potentially compromise the safety of critical systems. One such vulnerability has been identified in Solid Edge SE2023, a popular 3D CAD software, affecting all versions prior to V223.0 Update 10. This vulnerability, identified as CVE-2023-49127, could be exploited by attackers to execute arbitrary code in the context of the current process. This could potentially lead to full system compromise or data leakage, causing severe damage to businesses and organizations relying on this software.

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

The vulnerability stems from an out of bounds read issue that occurs while parsing specially crafted PAR files. An attacker with local access can craft a malicious PAR file, which when processed by the application, results in reading past the end of an allocated data structure. This could potentially allow an attacker to execute arbitrary code in the context of the current process.

Conceptual Example Code

While a specific exploit code is not provided, a conceptual example of an attack might look like this:

# Attacker crafts malicious PAR file
$ echo "malicious_code" > exploit.par
# Attacker gets the victim to process the malicious PAR file in Solid Edge SE2023
$ solid_edge_se2023 exploit.par

In this conceptual example, the attacker first crafts a malicious PAR file containing the exploit code. They then trick the victim into processing this malicious PAR file in Solid Edge SE2023, which due to the vulnerability, leads to the execution of the malicious code.

Prevention and Mitigation

The most effective way to mitigate this vulnerability is by applying the vendor-provided patch. If the patch cannot be applied immediately, it is recommended to use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary measure. However, these are not foolproof and could still leave the system vulnerable. Therefore, it is highly recommended to apply the vendor patch as soon as possible to ensure the security of your systems.
