CVE-2025-33246 is a command injection vulnerability classified under CWE-77, found in the NVIDIA NeMo Framework's ASR Evaluator utility across all platforms. The flaw exists because the utility improperly neutralizes special characters in a configuration parameter, allowing an attacker to inject arbitrary commands. This vulnerability can be exploited by a user with limited privileges (PR:L) without requiring user interaction (UI:N), and the attack vector is local (AV:L), meaning the attacker must have some level of access to the system. Exploitation could lead to arbitrary code execution, escalation of privileges, unauthorized data modification, and information leakage. The vulnerability affects all versions prior to 2.6.1, and while no public exploits are currently known, the high CVSS score of 7.8 reflects the serious risk posed. The underlying issue is a failure to properly sanitize input before passing it to system commands, a common and dangerous security flaw. The NeMo Framework is widely used in AI and speech recognition applications, making this vulnerability relevant to organizations leveraging NVIDIA's AI tools. The lack of a patch link suggests that users should monitor NVIDIA's official channels for updates and apply them promptly once available.

The impact of CVE-2025-33246 is significant for organizations using the NVIDIA NeMo Framework, particularly those deploying the ASR Evaluator utility in production or research environments. Successful exploitation can lead to full system compromise through arbitrary code execution and privilege escalation, undermining system integrity and confidentiality. Data tampering could corrupt speech recognition outputs or training data, affecting AI model accuracy and reliability. Information disclosure risks could expose sensitive data processed by the framework. The local attack vector limits exposure to insiders or compromised accounts, but the lack of required user interaction increases the likelihood of automated or scripted exploitation once access is gained. Organizations relying on NVIDIA NeMo for AI workloads in sectors such as technology, defense, healthcare, and finance could face operational disruptions, intellectual property theft, and regulatory compliance issues if exploited. The vulnerability also raises concerns for cloud environments where NeMo is deployed, as lateral movement within virtualized infrastructure could occur.

To mitigate CVE-2025-33246, organizations should immediately upgrade the NVIDIA NeMo Framework to version 2.6.1 or later once available, as this version addresses the command injection flaw. Until the patch is applied, restrict access to systems running the ASR Evaluator utility to trusted users only, minimizing the risk of local exploitation. Implement strict input validation and sanitization on all configuration parameters, especially those that influence command execution, to neutralize special characters and prevent injection. Employ application whitelisting and runtime application self-protection (RASP) mechanisms to detect and block suspicious command execution attempts. Conduct thorough code reviews and security testing on custom integrations with NeMo to identify and remediate similar injection vectors. Monitor system logs and audit trails for unusual command execution patterns indicative of exploitation attempts. Finally, educate developers and administrators about secure coding practices related to command invocation and parameter handling to prevent recurrence.
