CVE-2025-70070 is a medium-severity vulnerability found in Assimp version 6.0.2. This vulnerability allows a remote attacker to cause a denial of service (DoS) through a flaw in the FBXMeshGeometry.cpp file, specifically within the MeshGeometry::MeshGeometry() function. The CVSS score of 6.5 indicates a moderate level of risk, primarily due to its potential impact on system availability.
The ability of an attacker to exploit this vulnerability without requiring privileges makes it particularly concerning. The attack vector is categorized as network-based, which means that exploit attempts could be launched remotely, heightening the urgency for organizations to address this issue. As denial of service can disrupt operations, affected entities should be aware of the implications this vulnerability carries.
Currently, there is no known exploit publicly available for CVE-2025-70070, which is a critical point of consideration for organizations. However, given its potential for misuse, it is imperative that security teams actively monitor for updates and prepare for possible remediation actions. Organizations should prioritize patching or implementing workarounds to mitigate potential risks.
The CVE was published on May 4, 2026, and is listed as deferred, suggesting that it may not be actively tracked or prioritized by some organizations. Nonetheless, organizations that utilize Assimp should evaluate their exposure and consider addressing this vulnerability in their risk management strategies.
Organizations should act promptly to assess their vulnerability management programs and ensure that they are equipped to handle similar vulnerabilities in the future.
Vulnerability Details
An issue in Assimp v.6.0.2 allows a remote attacker to cause a denial of service via the FBXMeshGeometry.cpp, MeshGeometry::MeshGeometry(). The CVSS score for this vulnerability is 6.5, categorized as medium severity. The availability impact is marked as high, with no confidentiality or integrity impact.
The attack vector is network-based, requiring low complexity to exploit, no privileges, and some user interaction. The root cause appears to be related to improper input handling within the affected code.
Technical Analysis
The vulnerability's root cause lies in the FBXMeshGeometry.cpp file of the Assimp library. The attack vector is through network interactions, where an attacker can submit an input that leads to excessive resource consumption, effectively causing a denial of service. The complexity is rated as low, and no special privileges are needed to exploit this flaw, which requires user interaction.
In terms of impact, the vulnerability has a high availability impact, meaning it could lead to significant disruptions in service. There are no confidentiality or integrity impacts associated with this vulnerability, indicating that sensitive data is not at risk through this specific exploit.
Risk & Impact Analysis
Risk to organizations includes potential downtime and resource exhaustion caused by denial of service attacks. The fact that the vulnerability allows for remote exploitation without requiring elevated privileges means that it poses a significant risk to any organization using the affected version of Assimp. Given the nature of the vulnerability, its exploitation could lead to a considerable impact on operational continuity.
Organizations should assess their use of Assimp and related dependencies, implementing monitoring and alerting mechanisms to detect potential exploit attempts. The urgency for remediation is moderate, and organizations should schedule their patching efforts accordingly.
