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

CVE-2025-6636 is a severe vulnerability discovered in certain Autodesk products that can be exploited via a maliciously crafted PRT file. This vulnerability can potentially lead to a system compromise or data leakage. Given the widespread use of Autodesk products in industries ranging from architecture to entertainment, this vulnerability has the potential to affect a large number of systems<\/a> worldwide. It is therefore critical that users of affected Autodesk<\/a> products understand the nature of this vulnerability and take the necessary steps to mitigate its potential impact.<\/p>\n

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

CVE ID: CVE-2025-6636
\nSeverity: High (7.8 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System compromise<\/a> or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Autodesk AutoCAD | All versions prior to 2025.1
\nAutodesk Revit<\/a> | All versions prior to 2025.1<\/p>\n

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

The vulnerability revolves around the processing of PRT files<\/a> by certain Autodesk products. A malicious actor can craft a PRT file in such a way that it triggers a use-after-free vulnerability when parsed<\/a>. This could result in unexpected behaviors ranging from a system crash to the disclosure of sensitive data<\/a>. In the worst-case scenario, it can even allow the attacker to execute arbitrary code<\/a> in the context of the current process, potentially leading to a full system compromise.<\/p>\n

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

Below is a conceptual example of how the vulnerability might be exploited. In this scenario, a malicious actor sends a crafted PRT file to the target via<\/a> email. The target then unknowingly opens the file with a vulnerable<\/a> Autodesk product, triggering the exploit.<\/p>\n

# Attacker crafts malicious PRT file\necho \"malicious_code\" > exploit.prt\n# Attacker sends malicious PRT file to target\nmail -s \"Important Project File\" -a exploit.prt target@example.com<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
The best way to mitigate this vulnerability is by applying the patch provided by Autodesk<\/a>. If for some reason the patch cannot be immediately applied, a temporary workaround would be to employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability<\/a>. However, these are only temporary measures and applying the vendor patch as soon as possible remains the best course of action.<\/p>\n","protected":false},"excerpt":{"rendered":"
