Overview<\/strong><\/p>\n

A critical vulnerability, identified as CVE-2023-51439, has been discovered in multiple software applications including JT2Go and different versions of Teamcenter Visualization. The vulnerability is a result of an out of bounds read past the end of an allocated structure in the affected software, which can be triggered by parsing specially crafted CGM files. This vulnerability is significant as it allows potential attackers to execute arbitrary code in the context of the current process, which could lead to severe consequences such as system<\/a> compromise or data leakage.
\nThe affected applications are widely used in various industrial sectors, making this vulnerability a serious<\/a> concern that necessitates immediate attention and mitigation. Any organization or individual using the affected software versions should take swift action to protect their systems and data<\/a>.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2023-51439
\nSeverity: High (CVSS score of 7.8)
\nAttack Vector: Local file<\/a>
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

JT2Go | All versions < V14.3.0.6\nTeamcenter Visualization V13.3 | All versions<\/a> < V13.3.0.13\nTeamcenter Visualization<\/a> V14.1 | All versions < V14.1.0.12\nTeamcenter Visualization<\/a> V14.2 | All versions < V14.2.0.9\nTeamcenter Visualization V14.3 | All versions < V14.3.0.6\n\nHow the Exploit Works<\/strong><\/p>\n

The vulnerability involves an out of bounds read<\/a> flaw in the affected software. In this case, the software fails to properly handle the parsing of specially crafted CGM files. This could result in an out of bounds read<\/a> past the end of an allocated structure.
\nAn attacker with knowledge of this vulnerability could create a specially crafted CGM file<\/a>, which when processed by the affected software, could cause the application to read beyond the allocated memory. This could potentially allow the attacker to execute arbitrary code<\/a> in the context of the current process.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a conceptual representation of an exploit attempt. Please note that this is a simplified representation and actual exploit code would be more complex:<\/p>\n

#include \n#include \nint main() {\nchar* allocated_memory = (char*)malloc(10*sizeof(char));\nFILE* malicious_file = fopen(\"malicious.cgm\", \"r\");\n\/\/ force an out of bounds read\nfread(allocated_memory, sizeof(char), 20, malicious_file);\n\/\/ arbitrary code execution\nsystem(allocated_memory);\nreturn 0;\n}<\/code><\/pre>\n
In this example, a malicious CGM file is read into an allocated memory<\/a> block. The `fread` function reads more data than the allocated size, causing an out-of-bounds read<\/a>. The contents of the malicious CGM file could contain a command that is then executed<\/a> by the `system` function.<\/p>\n","protected":false},"excerpt":{"rendered":"
