Summary
by MITRE • 07/08/2025
A vulnerability has been identified in Solid Edge SE2025 (All versions < V225.0 Update 5). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted PAR files. This could allow an attacker to execute code in the context of the current process.

This vulnerability exists within Solid Edge SE2025 software version 225.0 Update 5 and earlier, representing a critical out-of-bounds read condition that occurs during PAR file parsing operations. The flaw manifests when the application processes specially crafted PAR files that contain malformed data structures, causing the software to attempt reading memory locations beyond the boundaries of allocated memory regions. This type of vulnerability falls under the CWE-125 category of Out-of-Bounds Read, which represents one of the most common and dangerous classes of memory corruption vulnerabilities. The issue arises from insufficient input validation and boundary checking within the PAR file parser component, where the application fails to properly verify array indices or structure sizes before accessing memory locations.
The operational impact of this vulnerability is severe as it provides attackers with a potential path for arbitrary code execution within the context of the currently running process. When a user opens a maliciously crafted PAR file, the out-of-bounds read condition can trigger memory corruption that may be exploited to overwrite critical program variables or function pointers. This type of vulnerability aligns with ATT&CK technique T1203 - Exploitation for Client Execution, where adversaries leverage software vulnerabilities to execute malicious code. The attack surface is particularly concerning given that PAR files are commonly used in engineering and design workflows, making them a plausible target for social engineering attacks where an unsuspecting user might open a compromised file. The vulnerability does not require elevated privileges to exploit, as it operates within the context of the standard user account running Solid Edge.
The technical exploitation of this vulnerability requires careful crafting of PAR files that trigger the specific memory access pattern leading to the out-of-bounds read. Attackers can potentially leverage this flaw to achieve remote code execution, allowing them to install malware, steal sensitive data, or establish persistent access to the affected system. The memory corruption resulting from the out-of-bounds read can be particularly dangerous because it may cause the application to crash or behave unpredictably, but more insidiously, it can be manipulated to redirect execution flow. This vulnerability represents a classic example of how seemingly benign file format parsing operations can become attack vectors when proper input validation is absent. Organizations using Solid Edge SE2025 should immediately implement mitigations including updating to version 225.0 Update 5 or later, implementing strict file access controls, and conducting security awareness training to prevent users from opening untrusted PAR files. Additionally, network segmentation and monitoring for suspicious file access patterns can help detect potential exploitation attempts. The vulnerability demonstrates the importance of proper bounds checking and input validation in preventing memory corruption exploits, aligning with security best practices outlined in the OWASP Top Ten and NIST Cybersecurity Framework.
