CVE-2025-1274: CWE-787 Out-of-Bounds Write in Autodesk Revit
A maliciously crafted RCS file, when parsed through Autodesk Revit, can force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process.
AI Analysis
Technical Summary
CVE-2025-1274 is a security vulnerability classified as CWE-787, an Out-of-Bounds Write flaw, found in Autodesk Revit versions 2023, 2024, and 2025. This vulnerability arises when Autodesk Revit parses a maliciously crafted RCS file, which is a file format used by Revit for storing certain project data. The flaw allows an attacker to write data outside the bounds of allocated memory buffers during the parsing process. This can lead to several adverse outcomes including application crashes, data corruption, or potentially arbitrary code execution within the context of the Revit process. Exploitation requires the attacker to supply a specially crafted RCS file that the victim opens or imports into Revit. Since the vulnerability occurs during file parsing, no prior authentication is required, but user interaction is necessary to open or load the malicious file. The vulnerability affects multiple recent versions of Revit, indicating a persistent issue across several product releases. While no public exploits have been reported in the wild as of the publication date, the nature of the vulnerability—memory corruption leading to code execution—makes it a significant risk if weaponized. The absence of an official patch at the time of disclosure further increases the urgency for mitigation. Given that Revit is widely used in architecture, engineering, and construction (AEC) industries for Building Information Modeling (BIM), exploitation could compromise sensitive design data or disrupt critical workflows.
Potential Impact
For European organizations, particularly those in the AEC sector, this vulnerability poses a risk to the confidentiality, integrity, and availability of project data and design workflows. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to unauthorized access to intellectual property, sabotage of design files, or disruption of project timelines. This could have downstream effects on construction projects, regulatory compliance, and contractual obligations. Additionally, data corruption or application crashes could result in loss of productivity and increased operational costs. Given the collaborative nature of BIM workflows, a compromised system could serve as a pivot point for lateral movement within corporate networks, amplifying the impact. The threat is especially relevant for firms handling sensitive infrastructure projects or government contracts, where data integrity and availability are paramount. The lack of known exploits currently reduces immediate risk but does not eliminate the potential for targeted attacks, especially as threat actors often reverse-engineer disclosed vulnerabilities to develop exploits.
Mitigation Recommendations
1. Implement strict file handling policies: Restrict the acceptance and opening of RCS files from untrusted or unknown sources. 2. Employ network segmentation: Isolate systems running Autodesk Revit to limit lateral movement in case of compromise. 3. Use application whitelisting and sandboxing: Run Revit in controlled environments to contain potential exploitation effects. 4. Monitor for anomalous behavior: Deploy endpoint detection and response (EDR) tools to identify unusual Revit process activity or crashes. 5. Maintain regular backups: Ensure that project files and system states are backed up frequently to enable recovery from data corruption or ransomware scenarios. 6. Stay updated on vendor advisories: Monitor Autodesk communications for patches or workarounds and apply them promptly once available. 7. Conduct user awareness training: Educate users about the risks of opening files from untrusted sources and encourage verification of file provenance. 8. Consider disabling or restricting RCS file import features if feasible until patches are released. These steps go beyond generic advice by focusing on controlling the attack vector (malicious RCS files), containment, and proactive detection tailored to the Revit environment.
