1. EXECUTIVE SUMMARY
o CVSS v3 7.8
o ATTENTION: Low attack complexity
o Vendor: Siemens
o Equipment: JT2GO, Teamcenter Visualization
o Vulnerabilities: Infinite Loop, Null Pointer Dereference, Integer Overflow
to Buffer Overflow, Double Free, Access of Uninitialized Pointer
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow an attacker to
trick a user to open a malicious file (crafted as CGM, TIFF or TG4) with any of
the affected products, which could lead the application to crash or to
arbitrary code execution.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following Siemens products are affected:
o JT2GO: All versions prior to v13.3.0.3
o Teamcenter Visualization v13.3: All versions prior to v13.3.0.3
o Teamcenter Visualization v14.0: All versions prior to v14.0.0.1
3.2 VULNERABILITY OVERVIEW
3.2.1 LOOP WITH UNREACHABLE EXIT CONDITION ('INFINITE LOOP') CWE-835
The Tiff_Loader.dll is vulnerable to infinite loop condition while parsing
specially crafted TIFF files. An attacker could leverage this vulnerability to
crash the application and cause a denial-of-service condition.
CVE-2022-29028 has been assigned to this vulnerability. A CVSS v3 base score of
3.3 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
C:N/I:N/A:L ).
3.2.2 NULL POINTER DEREFERENCE CWE-476
The CGM_NIST_Loader.dll contains a null pointer dereference vulnerability while
parsing specially crafted CGM files. An attacker could leverage this
vulnerability to crash the application and cause a denial-of-service condition.
CVE-2022-29029 has been assigned to this vulnerability. A CVSS v3 base score of
3.3 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
C:N/I:N/A:L ).
3.2.3 INTEGER OVERFLOW TO BUFFER OVERFLOW CWE-680
The Mono_Loader.dll library is vulnerable to integer overflow condition while
parsing specially crafted TG4 files. An attacker could leverage this
vulnerability to crash the application and cause a denial-of-service condition.
CVE-2022-29030 has been assigned to this vulnerability. A CVSS v3 base score of
3.3 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
C:N/I:N/A:L ).
3.2.4 NULL POINTER DEREFERENCE CWE-476
The affected product is vulnerable to a stack-based buffer overflow, which may
allow an attacker to remotely execute arbitrary code.
CVE-2022-29031 has been assigned to this vulnerability. A CVSS v3 base score of
3.3 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
C:N/I:N/A:L ).
3.2.5 DOUBLE FREE CWE-415
The CGM_NIST_Loader.dll library contains a double free vulnerability while
parsing specially crafted CGM files. An attacker could leverage this
vulnerability to execute code in the context of the current process.
CVE-2022-29032 has been assigned to this vulnerability. A CVSS v3 base score of
7.8 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
C:H/I:H/A:H ).
3.2.6 ACCESS OF UNINITIALIZED POINTER CWE-824
The CGM_NIST_Loader.dll library is vulnerable to uninitialized pointer free
while parsing specially crafted CGM files. An attacker could leverage this
vulnerability to execute code in the context of the current process.
CVE-2022-29033 has been assigned to this vulnerability. A CVSS v3 base score of
7.8 has been calculated; the CVSS vector string is ( AV:L/AC:L/PR:N/UI:R/S:U/
