CISA's summary
Summary: 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

Vulnerabilities in this advisory
- CVE-2020-26989 — CVE-2020-26989 · CWE-121
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)
- CVE-2020-26990 — CVE-2020-26990 · CWE-843
Affected applications lack proper validation of user-supplied data when parsing ASM files. A crafted ASM file could trigger a type confusion condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11897)
- CVE-2020-27000 — CVE-2020-27000 · CWE-119
Affected applications lack proper validation of user-supplied data when parsing BMP files. This can result in a memory corruption condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12018)
- CVE-2020-27003 — CVE-2020-27003 · CWE-822
Affected applications lack proper validation of user-supplied data when parsing TIFF files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12158)
- CVE-2020-27004 — CVE-2020-27004 · CWE-125
Affected applications lack proper validation of user-supplied data when parsing of CGM files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to access data in the context of the current process. (ZDI-CAN-12163)
- CVE-2020-27005 — CVE-2020-27005 · CWE-787
Affected applications lack proper validation of user-supplied data when parsing of TGA files. This could result in an out of bounds write past the end of an allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12178)
- CVE-2020-27006 — CVE-2020-27006 · CWE-119
Affected applications lack proper validation of user-supplied data when parsing of PCT files. This could result in a memory corruption condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12182)
- CVE-2020-27007 — CVE-2020-27007 · CWE-125
Affected applications lack proper validation of user-supplied data when parsing of HPG files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to access data in the context of the current process. (ZDI-CAN-12207)
- CVE-2020-27008 — CVE-2020-27008 · CWE-125
Affected applications lack proper validation of user-supplied data when parsing of PLT files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to access data in the context of the current process. (ZDI-CAN-12209)
- CVE-2020-28383 — CVE-2020-28383 · CWE-787
Affected applications lack proper validation of user-supplied data when parsing PAR files. This can result in an out of bounds write past the memory location that is a read only image address. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11885)
- CVE-2020-28394 — CVE-2020-28394 · CWE-125
Affected applications lack proper validation of user-supplied data when parsing of RAS files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to access data in the context of the current process. (ZDI-CAN-12283)
