CVE-2024-24923: CWE-125: Out-of-bounds Read in Siemens Simcenter Femap
A vulnerability has been identified in Simcenter Femap (All versions < V2401.0000), Simcenter Femap (All versions < V2306.0001). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted Catia MODEL files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-22055)
AI Analysis
Technical Summary
CVE-2024-24923 is a high-severity vulnerability identified in Siemens Simcenter Femap, a widely used engineering simulation software. The flaw exists in all versions prior to V2401.0000 and V2306.0001. It is caused by an out-of-bounds read (CWE-125) occurring when the application parses specially crafted Catia MODEL files. Specifically, the software reads beyond the allocated memory boundary of a structure, which can lead to memory corruption. This vulnerability can be exploited by an attacker who crafts a malicious Catia MODEL file and convinces a user to open it in the vulnerable Simcenter Femap application. Successful exploitation allows the attacker to execute arbitrary code within the context of the current process, potentially leading to full compromise of the affected system. The CVSS 3.1 base score is 7.8, indicating a high severity level. The vector string (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C) shows that the attack requires local access (AV:L), low complexity (AC:L), no privileges (PR:N), but user interaction (UI:R) to open the malicious file. The impact on confidentiality, integrity, and availability is high, and the exploitability is partially functional (E:P) with official remediation planned (RL:O) and confirmed (RC:C). No known exploits are currently in the wild. This vulnerability is significant because Simcenter Femap is used in critical engineering and manufacturing environments where simulation data integrity and system reliability are paramount. An attacker gaining code execution could manipulate simulation results, steal intellectual property, or disrupt engineering workflows.
Potential Impact
For European organizations, particularly those in aerospace, automotive, manufacturing, and industrial engineering sectors, this vulnerability poses a substantial risk. Siemens Simcenter Femap is commonly used in these industries for finite element analysis and simulation tasks. Exploitation could lead to unauthorized code execution, enabling attackers to alter simulation data, compromise design integrity, or exfiltrate sensitive intellectual property. This could result in flawed product designs, safety issues, financial losses, and reputational damage. Additionally, disruption of engineering workflows could delay product development cycles. Given the critical nature of these industries in Europe’s economy and the reliance on Siemens software, the impact could extend to national infrastructure and supply chains. The requirement for local access and user interaction somewhat limits remote exploitation but insider threats or targeted spear-phishing campaigns delivering malicious files remain a concern. The high confidentiality, integrity, and availability impact underscores the need for urgent mitigation in affected environments.
Mitigation Recommendations
1. Immediate application of Siemens’ official patches or updates once released for versions prior to V2401.0000 and V2306.0001 is critical. Monitor Siemens security advisories for patch availability. 2. Until patches are available, implement strict file handling policies: restrict opening Catia MODEL files from untrusted or unknown sources within Simcenter Femap. 3. Employ endpoint protection solutions capable of detecting anomalous behavior or exploitation attempts related to Simcenter Femap. 4. Conduct user awareness training focused on the risks of opening unsolicited or suspicious engineering files. 5. Use application whitelisting and sandboxing techniques to limit the execution context of Simcenter Femap and contain potential exploits. 6. Monitor logs and network traffic for unusual activity originating from systems running Simcenter Femap. 7. Consider network segmentation to isolate engineering workstations to reduce the risk of lateral movement if compromise occurs. 8. Regularly back up critical simulation data and verify integrity to enable recovery from potential tampering or ransomware attacks.
