Description

CVE-2025-23243 describes an improper access control vulnerability within NVIDIA Riva. Successful exploitation of this vulnerability could allow an attacker to tamper with data or cause a denial-of-service (DoS) condition. The SOCRadar Vulnerability Risk Score (SVRS) is 30, indicating a low to medium level of risk. While the CVSS score is 0, the SVRS considers real-world threat intelligence, including the fact that this vulnerability is marked as being exploited In The Wild, suggesting active exploitation by hackers.

Key Insights

1. Active Exploitation in the Wild: Despite the low CVSS score, the "In The Wild" tag signifies that this vulnerability is actively being exploited by attackers, increasing the urgency for remediation.
2. Potential for Data Tampering and Denial of Service: Successful exploitation could lead to significant disruption, as the improper access control issue could allow for unauthorized modification of data or a complete disruption of service for NVIDIA Riva users.
3. Improper Access Control (CWE-284): The vulnerability stems from inadequate access control mechanisms, meaning attackers can bypass intended restrictions to perform actions they shouldn't be authorized to do.

Mitigation Strategies

1. Apply Available Patches and Updates: Immediately apply any patches or updates released by NVIDIA for Riva to address CVE-2025-23243. This is the most direct way to remediate the vulnerability.
2. Review and Strengthen Access Control Policies: Evaluate existing access control configurations within NVIDIA Riva and implement stricter policies to limit unauthorized access and prevent potential data tampering or denial-of-service attacks.
3. Implement Intrusion Detection and Prevention Systems (IDS/IPS): Deploy or enhance IDS/IPS solutions to detect and block malicious traffic and exploitation attempts targeting CVE-2025-23243, supplementing access control measures.
