EPSS · bewertet 2026-10-27

A vulnerability has been identified in JT2Go (All versions < V13.1.0.1), Solid Edge SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2), Teamcenter Visualization (All versions < V13.1.0.1). Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a stack based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11892)

  • SSA-663999SSA-663999: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.1.0.12021-02-09csaf · siemens_psirtDE

    Siemens has released version V13.1.0.1 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (BMP, TIFF, CGM, TGA, PCT, HPG, PLT, RAS, PAR, ASM, DXF, DWG). If a user is tricked to opening of a malicious file with the affected products, this could lead to application crash, or potentially arbitrary code execution or data extraction on the target host system. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products. Notes: - Previous versions of this advisory incorrectly listed the following vulnerabilities as being fixed in V13.1.0.1: CVE-2020-26991, CVE-2020-26998, CVE-2020-26999, CVE-2020-27001 and CVE-2020-27002. Those were fixed in V13.1.0.2 and are therefore addressed in advisory SSA-695540 [0] - The vulnerability CVE-2020-28383 was incorrectly listed in SSA-622830 [1] as being fixed in V13.1.0.0. This was fixed in V13.1.0.1 and therefore added here - The Open Design Alliance [2] recently disclosed an additional vulnerability (CVE-2021-31784) which is also covered in this advisory [0] https://cert-portal.siemens.com/productcert/pdf/ssa-622830.pdf [1] https://cert-portal.siemens.com/productcert/pdf/ssa-695540.pdf [2] https://www.opendesign.com/security-advisories

    As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
