Description

A maliciously crafted RTE file, when parsed through Autodesk Revit, can force a Heap-Based Overflow vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process.

Technical Analysis

CVE-2025-5040 is a high-severity heap-based buffer overflow vulnerability identified in Autodesk Revit versions 2024, 2025, and 2026. The vulnerability arises when a maliciously crafted RTE file is parsed by Revit, leading to an overflow condition on the heap memory. This type of vulnerability (CWE-122) occurs when a program writes more data to a buffer located on the heap than it was allocated to hold, potentially overwriting adjacent memory. Exploiting this flaw allows an attacker to cause a denial of service (application crash), read sensitive information from memory, or execute arbitrary code with the privileges of the current process. The CVSS 3.1 base score of 7.8 reflects a high impact on confidentiality, integrity, and availability, with the attack vector being local (AV:L), requiring low attack complexity (AC:L), no privileges (PR:N), but user interaction (UI:R) is necessary to trigger the vulnerability. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize monitoring and mitigation efforts. Autodesk Revit is widely used in architecture, engineering, and construction sectors for Building Information Modeling (BIM), making this vulnerability particularly critical due to the sensitive nature of design data and intellectual property involved. The ability to execute arbitrary code could allow attackers to move laterally within networks or exfiltrate proprietary designs.

Potential Impact

For European organizations, especially those in architecture, engineering, construction, and related industries, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive design data, intellectual property theft, and disruption of critical project workflows. Given the collaborative nature of BIM projects, a successful attack could propagate through shared files and networks, amplifying damage. Additionally, the potential for arbitrary code execution could enable attackers to establish persistence, escalate privileges, or deploy ransomware within corporate environments. This could result in financial losses, reputational damage, and regulatory penalties under GDPR if personal or sensitive data is compromised. The requirement for user interaction suggests phishing or social engineering could be vectors, increasing the risk in environments with less mature cybersecurity awareness.

Mitigation Recommendations

Organizations should implement a multi-layered approach: 1) Restrict the opening of RTE files from untrusted or unknown sources, employing strict file validation and sandboxing where possible. 2) Educate users on the risks of opening unsolicited or suspicious files, emphasizing the need for caution with RTE files. 3) Monitor Autodesk’s security advisories closely for patches or updates addressing CVE-2025-5040 and apply them promptly once available. 4) Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior indicative of exploitation attempts. 5) Use network segmentation to isolate systems running Autodesk Revit, limiting lateral movement opportunities. 6) Implement robust backup and recovery procedures to mitigate potential ransomware or data loss scenarios. 7) Consider deploying runtime application self-protection (RASP) or memory protection technologies that can detect or prevent heap overflow exploitation in real-time.
