A high-severity vulnerability has been identified in Hugging Face Transformers, specifically within the MaskFormer Model. This vulnerability allows remote attackers to execute arbitrary code on affected installations. User interaction is required for exploitation, meaning that the target must visit a malicious page or open a malicious file. The flaw arises from improper validation of user-supplied data during the parsing of model files. This lack of validation can lead to deserialization of untrusted data, enabling an attacker to execute code in the context of the current user.
With a CVSS score of 8.8, this vulnerability poses a significant threat to organizations utilizing Hugging Face Transformers. The high severity rating indicates that the potential impact on confidentiality, integrity, and availability is severe. Organizations should prioritize immediate remediation to mitigate the risks associated with this vulnerability.
As of now, there is no public exploit confirmed, but the vulnerability is actively being discussed in various technical forums, heightening the urgency for organizations to address it.
Organizations should prioritize patching immediately to safeguard against potential exploits. Regularly monitoring for updates from Hugging Face will also be essential in ensuring continued security.
Vulnerability Details
The vulnerability identified as CVE-2024-11393 involves a deserialization of untrusted data in Hugging Face Transformers. The flaw is categorized under CWE-502, which pertains to deserialization of untrusted data. The vulnerability has been given a CVSS score of 8.8, indicating high severity. The attack vector is classified as network-based, and the attack complexity is low, requiring no privileges from the attacker, but necessitating user interaction.
The affected product is Hugging Face Transformers, specifically versions before 4.48.0. The vulnerability was disclosed on November 22, 2024, and is currently under analysis.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user-supplied data during the parsing of model files. This oversight allows an attacker to provide malicious input that can be deserialized, leading to remote code execution.
The attack vector is network-based, meaning that the vulnerability can be exploited over the internet. The attack complexity is low, which means that the vulnerability can be exploited without significant technical skill. Additionally, no privileges are required for exploitation, but user interaction is necessary, as the target must engage with malicious content.
The impact of this vulnerability is severe, affecting confidentiality, integrity, and availability of the system. If exploited, an attacker could execute arbitrary code, potentially taking control of the affected system.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data, system compromise, and disruption of services. The high impact on confidentiality, integrity, and availability necessitates urgent action. With the high likelihood of exploitation and severe consequences, organizations should address this vulnerability in their priority patch cycle.
Organizations should prioritize patching immediately, as the potential for exploitation is significant given the current threat landscape. Affected installations of Hugging Face Transformers must be updated to version 4.48.0 or later to mitigate the risks associated with this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
