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

The cybersecurity landscape is constantly evolving and one such manifestation of this evolution is the discovery of an Out-of-Bounds Read vulnerability in certain Autodesk products, as identified by the Common Vulnerabilities and Exposures (CVE) identifier CVE-2025-6635. This vulnerability stems from the mishandling of maliciously crafted PRT files which, when imported or linked into vulnerable Autodesk products, can lead to unintended consequences. This vulnerability has the potential to affect a wide range<\/a> of users, spanning from individual users to large enterprises, given the widespread usage of Autodesk products. This makes it a significant concern that should be addressed promptly.<\/p>\n

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

CVE ID: CVE-2025-6635
\nSeverity: High (7.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Autodesk AutoCAD | All versions prior to 2025 Patch 1
\nAutodesk Inventor | All versions prior to 2025 Update 2<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The out-of-bounds read vulnerability is triggered when an Autodesk<\/a> product attempts to process a maliciously crafted PRT file. The exploit takes advantage of the software’s lack of proper validation of user-supplied input<\/a>. This allows a malicious actor to force the software to read beyond the intended boundary of the targeted data structure, potentially leading to a crash, data leakage, or arbitrary code execution<\/a>.<\/p>\n

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

This conceptual example illustrates how a malicious actor might craft a PRT file to exploit this vulnerability<\/a>:<\/p>\n

#include \nint main() {\n\/\/ Create a buffer with more data than expected\nchar buffer[256] = {0};\nFILE *file = fopen(\"malicious.prt\", \"rb\");\n\/\/ If the file exists, read the data\nif (file != NULL) {\nfread(buffer, 1, 512, file);\nfclose(file);\n}\n\/\/ The buffer is now filled with more data than it can handle, causing an out-of-bounds read\nprintf(\"%s\\n\", buffer);\nreturn 0;\n}<\/code><\/pre>\n
This example is overly simplified to demonstrate the concept, and the actual exploit would likely involve more complex manipulations and obfuscations.<\/p>\n
Mitigation<\/strong><\/p>\n
The recommended mitigation for this vulnerability is to apply the vendor-issued patch as soon as it becomes available. Until the patch can be applied, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by filtering out malicious PRT files. Regular monitoring of system logs and network traffic can also aid in identifying any attempts to exploit this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
