Lifecycle Timeline
6DescriptionCVE.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.
AnalysisAI
Use-after-free in Siemens Solid Edge SE2025 and SE2026 enables arbitrary code execution in the context of the current process when a user opens a specially crafted DFT file. Both affected annual release branches are vulnerable until patched - SE2025 prior to V225.0 Update 15 and SE2026 prior to V226.0 Update 7 - as confirmed by Siemens Security Advisory SSA-621657. No public exploit or active exploitation has been identified at time of analysis; the CVSS 4.0 AC:H rating indicates non-trivial exploit development is required.
Technical ContextAI
The flaw is a use-after-free (CWE-416) in the DFT (Draft) file parser of Siemens Solid Edge, an industrial 3D CAD application. Use-after-free vulnerabilities occur when heap-allocated memory is freed but a dangling pointer retains a reference to it; a subsequent dereference of that pointer can allow an attacker to corrupt memory, redirect control flow, or disclose heap contents. The DFT format is Solid Edge's native 2D drafting file type - a complex binary format that historically attracts memory-safety flaws due to the richness and structural variability of the data it encodes. CPE strings cpe:2.3:a:siemens:solid_edge_se2025 and cpe:2.3:a:siemens:solid_edge_se2026 confirm the two affected annual release trains. The tags accompanying this CVE (Memory Corruption, Information Disclosure) are consistent with heap-UAF exploitation paths that may also leak pointer values prior to control-flow hijack.
RemediationAI
Siemens has released patched builds for both affected release trains: upgrade Solid Edge SE2025 to V225.0 Update 15 or later, and Solid Edge SE2026 to V226.0 Update 7 or later, as documented in SSA-621657 at https://cert-portal.siemens.com/productcert/html/ssa-621657.html. Where immediate patching is not operationally feasible, organizations should block DFT files received from untrusted external sources at the email gateway and file-sharing perimeter, and disable Windows Explorer thumbnail or preview handlers for Solid Edge file types to prevent incidental parsing. Running Solid Edge under a restricted AppLocker or Software Restriction Policy profile can limit the blast radius of a successful exploit by constraining the process's filesystem and network access. User awareness training specific to DFT files from unknown senders is a low-cost compensating control, though it carries the inherent limitation of human reliability.
