CVE-2025-70071 is a medium-severity vulnerability discovered in Assimp version 6.0.2. This vulnerability allows a remote attacker to cause a denial of service via the FBXParser.cpp, specifically in the ParseVectorDataArray() function. The CVSS score of 5.9 indicates that while the attack vector requires network access, the complexity is rated as high, meaning it may require specific conditions to exploit.
Risk to organizations includes potential service disruption due to denial of service, affecting availability. Given the vulnerability's deferred status, it is crucial for organizations using Assimp to monitor developments and allocate resources for potential remediation. Organizations should prioritize patching immediately.
Currently, there is no known exploit or public proof of concept. However, organizations must remain vigilant, as the lack of public information does not diminish the risk associated with this vulnerability.
Organizations utilizing Assimp should integrate this information into their vulnerability management program and ensure they are prepared to respond should this vulnerability become actively exploited.
Vulnerability Details
The vulnerability is categorized under CWE-400 (Uncontrolled Resource Consumption) and CWE-770 (Allocation of Resources Without Limits). The attack complexity is high, and privileges required are none, meaning an unauthenticated user can trigger the vulnerability. The denial of service impact is rated as high, affecting the availability of the service.
Technical Analysis
The root cause of CVE-2025-70071 stems from improper handling of certain data structures within the Assimp library's FBX file parser. An attacker could craft a malicious FBX file that, when processed by the vulnerable version of Assimp, leads to excessive resource consumption, ultimately resulting in a denial of service.
The attack vector is network-based, as the vulnerability can be exploited via crafted files sent over the internet. The complexity of the attack is categorized as high, possibly requiring specific knowledge of the Assimp file processing logic. No user interaction is necessary, making it easier for an attacker to exploit the vulnerability.
The impacts on confidentiality and integrity are rated as none, while the availability impact is rated as high, indicating that successful exploitation can lead to significant service disruptions for users.
Risk & Impact Analysis
Organizations using Assimp should assess their exposure to this vulnerability, particularly if they handle external FBX files or provide services that rely on FBX processing. The potential for denial of service could disrupt service availability, significantly impacting user experience and operational continuity.
With a CVSS score of 5.9, this vulnerability is classified as medium severity, warranting attention within an organization's patch management cycle. The presence of high attack complexity suggests that while it may not be an immediate threat, organizations should not ignore the potential risk it poses.
Given the relatively low EPSS score of 0.000420000, this vulnerability is currently less likely to be exploited in the wild, but organizations should not become complacent. Regular monitoring, along with an effective vulnerability management strategy, is essential.
