AI-suggested
European organizations should immediately implement the following mitigations: 1) Restrict and monitor the handling of PAR files within the environment, especially from untrusted sources. 2) Educate users on the risks of opening unsolicited or unexpected PAR files and implement strict email filtering to block potentially malicious attachments. 3) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior related to Solid Edge processes. 4) Use application whitelisting and sandboxing to limit the execution context of Solid Edge and isolate it from critical systems. 5) Regularly back up design data and maintain version control to recover from potential tampering. 7) Conduct vulnerability scanning and penetration testing focused on CAD environments to identify exposure. 8) Implement network segmentation to isolate engineering workstations from broader corporate networks to limit lateral movement in case of compromise.
Description
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.
