mediumpriority · track · 32EPSS 0.028 · 86 %ileDEEUUSEPSS · scored 2026-10-27
An out-of-bounds write issue exists in the DXF file-recovering procedure in the Drawings SDK (All versions prior to 2022.4) resulting from the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated buffer and allow attackers to cause a denial-of-service condition or execute code in the context of the current process.

advisories (7)
Vendor and ecosystem advisories describing this.
- SSA-155599SSA-155599: File Parsing Vulnerabilities in COMOS2022-03-08csaf · siemens_psirtDE
COMOS uses Drawings SDK from Open Design Alliance that is affected by multiple vulnerabilities that could be triggered when the application reads files in DGN, DXF or DWG file formats. If a user is tricked to open a malicious file with the affected application, an attacker could leverage the vulnerability to leak information or potentially perform remote code execution in the context of the current process. Siemens has released an update for the COMOS and recommends to update to the latest version.
- SSA-365397SSA-365397: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.2.0.12021-08-10csaf · siemens_psirtDE
Siemens has released version V13.2.0.1 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (CGM, DGN, DXF, and DWG). If a user is tricked to open a malicious file with the affected products, this could lead the application to crash or potentially arbitrary code execution. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products. Note: - This advisory also covers security vulnerabilities recently disclosed by Open Design Alliance [0] [0] https://www.opendesign.com/security-advisories
- SSA-491245SSA-491245: Multiple File Parsing Vulnerabilities in Solid Edge2023-02-14csaf · siemens_psirtDE
Solid Edge is affected by multiple memory corruption vulnerabilities that could be triggered when the application reads specially crafted files in various formats such as X_B, DWG, DXF, STL, STP, SLDPRT and PAR format. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to crash the application, extract data or potentially lead to arbitrary code execution. Siemens has released updates for the affected products and recommends to update to the latest versions.
