DescriptionNVD

An Out-of-Bounds Write vulnerability exists when reading a DXF or DWG file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF and DWG files. Crafted data in a DXF or DWG file (an invalid number of properties) can trigger a write operation past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

AnalysisAI

An Out-of-Bounds Write vulnerability exists when reading a DXF or DWG file using Open Design Alliance Drawings SDK before 2022.11. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. An Out-of-Bounds Write vulnerability exists when reading a DXF or DWG file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF and DWG files. Crafted data in a DXF or DWG file (an invalid number of properties) can trigger a write operation past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Affected products include: Opendesign Drawings Software Development Kit, Siemens Jt2Go, Siemens Solid Edge, Siemens Teamcenter Visualization. Version information: before 2022.11..

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
