Critical Out-of-Bounds Read Vulnerability in Siemens Solid Edge (CVE-2026-0001)

3 min readSource: CISA Cybersecurity Advisories

CISA warns of a high-severity out-of-bounds read flaw in Siemens Solid Edge's PS/IGES Parasolid Translator, exploitable via malicious IGS files.

Siemens Solid Edge Vulnerability Exposes Systems to Malicious File Attacks

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has disclosed a critical vulnerability in Siemens Solid Edge, a widely used computer-aided design (CAD) software suite. The flaw, tracked as CVE-2026-0001, stems from an out-of-bounds read issue in the PS/IGES Parasolid Translator Component, which could be exploited when processing files in IGS format.

Technical Details

  • CVE ID: CVE-2026-0001
  • Affected Component: PS/IGES Parasolid Translator (used for IGS file parsing)
  • Vulnerability Type: Out-of-bounds read
  • Attack Vector: Malicious IGS files delivered via phishing or file-sharing
  • Impact: Potential arbitrary code execution or application crash if a user opens a crafted file

The vulnerability occurs when Solid Edge processes specially crafted IGS files, allowing attackers to trigger memory corruption. While CISA’s advisory does not specify the exact exploitation mechanism, out-of-bounds read flaws can often lead to information disclosure, code execution, or denial-of-service (DoS) conditions if leveraged successfully.

Impact Analysis

Organizations using Siemens Solid Edge for industrial design, manufacturing, or engineering workflows are at risk. An attacker could:

  • Deliver malicious IGS files via phishing emails, compromised file-sharing platforms, or supply chain attacks.
  • Exploit the flaw to execute arbitrary code in the context of the affected application, potentially gaining unauthorized access to sensitive design data.
  • Disrupt operations by crashing the application, leading to productivity losses in CAD-dependent environments.

Given the software’s prevalence in industrial control systems (ICS) and operational technology (OT) environments, this vulnerability could have cascading effects on critical infrastructure sectors.

Recommendations for Security Teams

  1. Apply Siemens’ Patch: Siemens has released updates addressing this vulnerability. Organizations should:

    • Download and install the latest version of Solid Edge from the official Siemens support portal.
    • Follow Siemens’ advisory for mitigation guidance.

  2. Restrict File Handling:

    • Limit the use of IGS files from untrusted sources.
    • Implement sandboxing or application whitelisting to restrict Solid Edge’s execution in high-risk environments.

  3. User Awareness Training:

    • Educate employees on the risks of opening unsolicited CAD files, even from seemingly legitimate sources.
    • Emphasize phishing-resistant authentication (e.g., MFA) to reduce the risk of credential theft enabling file-based attacks.

  4. Monitor for Exploitation:

    • Deploy endpoint detection and response (EDR) solutions to detect anomalous behavior in Solid Edge processes.
    • Review logs for unexpected crashes or file access patterns indicative of exploitation attempts.

  5. Network Segmentation:

    • Isolate systems running Solid Edge from critical OT networks to limit lateral movement in case of compromise.

CISA’s advisory (ICSA-26-043-05) provides additional technical details and should be reviewed by security teams managing Siemens Solid Edge deployments.
