MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires that the victim open a specially crafted DFT file using an unpatched version of Siemens Solid Edge SE2025 (prior to V225.0 Update 15) or SE2026 (prior to V226.0 Update 7) on their local workstation. The attack vector is strictly local (AV:L in CVSS 4.0): the attacker must first deliver the malicious file to the target's filesystem - network-based remote exploitation without file delivery is not indicated. User interaction is mandatory (UI:P); the vulnerability cannot be triggered without the user explicitly opening the DFT file in the application. High attack complexity (AC:H) further requires the attacker to satisfy specific memory-state conditions at time of exploitation. No authentication to the system or application is required beyond what is implicit in running a user-space process. Non-default configuration is not required - the DFT format is a standard Solid Edge document type. |
| Impact | The CVSS 4.0 score of 7.3 is driven by high impact across confidentiality, integrity, and availability of the vulnerable system, but is meaningfully discounted by a local attack vector (AV:L), high attack complexity (AC:H), and a mandatory user interaction step (UI:P). No EPSS data was provided in the intelligence feed, so probabilistic exploitation estimates cannot be cited. The vulnerability is not listed in the CISA KEV catalog and no POC has been identified, indicating no confirmed or widespread exploitation activity. The AC:H rating signals that reliable exploitation likely requires precise heap-spray or memory-grooming techniques, raising the bar beyond commodity-level attackers. Even a mid-sized municipal IT team in leszno managing a small fleet of engineering workstations running Solid Edge should treat this as a watch-and-patch item rather than an emergency, given the requirement for the user to actively open a malicious DFT file. The most realistic threat actor is a targeted adversary conducting industrial espionage - delivering a weaponized DFT via spearphishing to an engineer - rather than opportunistic mass exploitation. |
| Exploit ScenarioDerived | An adversary targeting an engineering firm crafts a malicious DFT file and delivers it to a Solid Edge user as an email attachment - for example, disguised as a shared design revision. When the engineer opens the file, the DFT parser triggers the use-after-free condition, enabling the attacker to execute code in the context of the Solid Edge process and potentially exfiltrate proprietary CAD design data or establish a foothold on the workstation. No public exploit code has been identified at time of analysis, so exploitation requires attacker-developed tooling and reliable heap manipulation under AC:H conditions. |

Alert meAnalysisAIv3 – Aug 11, 2026
Use-after-free memory corruption in Siemens Solid Edge SE2025 and SE2026 allows code execution in the context of the current user process when a specially crafted DFT (draft) file is parsed. Affected are all SE2025 releases prior to V225.0 Update 15 and all SE2026 releases prior to V226.0 Update 7, as confirmed by Siemens advisory SSA-621657. No public exploit code or active exploitation has been identified at time of analysis, and the local attack vector combined with required user interaction meaningfully constrains real-world exposure.
Earlier versions of this analysis (2)
Use-after-free code execution in Siemens Solid Edge SE2025 and SE2026 is triggered when the application parses a specially crafted DFT (Solid Edge Draft) file, allowing arbitrary code to run in the context of the victim's process. Affected versions include Solid Edge SE2025 before V225.0 Update 15 and SE2026 before V226.0 Update 7, as confirmed in Siemens advisory SSA-621657. No public exploit has been identified at time of analysis, and the local attack vector with user interaction requirement constrains opportunistic exploitation to targeted file-delivery scenarios.
Code execution via use-after-free in Siemens Solid Edge's DFT file parser affects SE2025 (all versions before V225.0 Update 15) and SE2026 (all versions before V226.0 Update 7). An attacker who convinces a user to open a specially crafted DFT file can execute arbitrary code in the context of the current process, with full confidentiality, integrity, and availability impact on the affected workstation. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA's Known Exploited Vulnerabilities catalog.
RemediationAI
Vendor-released patches are available: upgrade Solid Edge SE2025 to V225.0 Update 15 or later, and Solid Edge SE2026 to V226.0 Update 7 or later, as detailed in Siemens advisory SSA-621657 at https://cert-portal.siemens.com/productcert/html/ssa-621657.html. Until patching is complete, the most effective compensating control is user-awareness guidance instructing engineers not to open DFT files received from untrusted or unverified external sources - this directly targets the required user-interaction step (UI:P) and eliminates the primary delivery vector. Where operationally feasible, restricting file-association handling so that DFT files from email attachments or downloads do not auto-open in Solid Edge reduces incidental exposure with minimal workflow impact. Network-level controls are not applicable given the local attack vector.

Technical ContextAI · show details
Solid Edge is a Siemens CAD/CAM/CAE suite widely used in industrial and manufacturing design workflows. The vulnerable component is the DFT file parser - DFT is the Solid Edge proprietary draft/drawing file format. The root cause is CWE-416 (Use After Free): the parser frees a memory object during DFT processing but subsequently dereferences the stale pointer, creating a condition an attacker can exploit to redirect execution. Use-after-free bugs in file parsers typically arise from object lifetime mismanagement across complex parse-state machines. Affected CPE identifiers are cpe:2.3:a:siemens:solid_edge_se2025:*:*:*:*:*:*:*:* (all builds before V225.0 Update 15) and cpe:2.3:a:siemens:solid_edge_se2026:*:*:*:*:*:*:*:* (all builds before V226.0 Update 7). The CVSS 4.0 scope is confined to the vulnerable system (SC:N/SI:N/SA:N), meaning the flaw does not inherently propagate beyond the Solid Edge process itself.

Lifecycle Timeline
4DescriptionCVE.org
A vulnerability has been identified in Solid Edge SE2025 (All versions < V225.0 Update 15), Solid Edge SE2026 (All versions < V226.0 Update 7). The affected applications contain a use-after-free vulnerability that could be triggered while parsing specially crafted DFT files. This could allow an attacker to execute code in the context of the current process.
Executive ViewAI
Siemens Solid Edge (SE2025 and SE2026) contains a use-after-free vulnerability allowing code execution within user process context when opening malicious draft files, directly threatening design intellectual property and system integrity for engineering teams. This vulnerability affects all versions prior to Solid Edge SE2025 V225.0 Update 15 and SE2026 V226.0 Update 7, creating risk to R&D departments and external collaboration workflows. While the local attack vector and required user interaction limit immediate enterprise exposure, organizations must prioritize patching to prevent insider threats and compromised file scenarios.
Vendor-released patch: Siemens Solid Edge SE2025 V225.0 Update 15 and later; SE2026 V226.0 Update 7 and later (per Siemens advisory SSA-621657). Interim mitigation: restrict draft file imports from untrusted sources, disable macro execution in CAD applications, and monitor file access logs for suspicious .dft parsing activity.

Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
