CVE-2025-34090
AI Analysis
Technical Summary
CVE-2025-34090 is a vulnerability identified in Google Chrome, as recorded in the CVE Database version 5. The CVSS vector string provided (CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) indicates a complex and severe vulnerability affecting confidentiality, integrity, and availability with high impact across all three security objectives. The attack vector is local (AV:L), meaning the attacker must have local access to the system. The attack complexity is low (AC:L), and no user interaction (UI:N) or attacker privileges (PR:L) beyond limited privileges are required. The vulnerability affects a high scope (SC:H), indicating that the impact extends beyond the vulnerable component to other components or systems. The vulnerability impacts confidentiality (VC:H), integrity (VI:H), and availability (VA:H) at high levels, and the scope (SI:H) and security requirements (SA:H) are also high, suggesting critical importance of the affected system. Although no specific affected versions or technical details are provided, the vulnerability is in Google Chrome, a widely used web browser. No known exploits are reported in the wild, and no patches or mitigations have been linked yet. The vulnerability was reserved in April 2025 and published in July 2025, indicating recent discovery. The lack of detailed technical information limits precise understanding, but the CVSS vector suggests a serious local privilege escalation or sandbox escape vulnerability that could allow an attacker with limited local access to fully compromise the browser and potentially the underlying system, severely impacting confidentiality, integrity, and availability of user data and system resources.
Potential Impact
For European organizations, this vulnerability poses a significant risk due to the widespread use of Google Chrome across enterprises, government agencies, and critical infrastructure sectors. A successful exploitation could lead to unauthorized access to sensitive information, data corruption, or denial of service conditions, undermining trust and operational continuity. The local attack vector implies that attackers would need some form of initial access, such as through insider threats, compromised endpoints, or physical access, which is plausible in many organizational environments. The high impact on confidentiality, integrity, and availability could result in data breaches, intellectual property theft, disruption of services, and compliance violations with regulations such as GDPR. The absence of known exploits in the wild currently reduces immediate risk but also highlights the urgency for proactive mitigation before potential exploitation emerges. The high scope impact suggests that the vulnerability could affect multiple components or systems beyond the browser itself, increasing the potential damage within interconnected IT environments common in European organizations.
Mitigation Recommendations
Given the lack of specific patches or detailed technical information, European organizations should implement the following targeted mitigations: 1) Enforce strict local access controls and endpoint security measures to prevent unauthorized local access, including robust authentication, endpoint detection and response (EDR) solutions, and least privilege policies. 2) Monitor for unusual local activity on systems running Chrome, focusing on privilege escalation attempts or anomalous process behavior. 3) Restrict installation and execution of untrusted software and scripts that could facilitate local exploitation. 4) Maintain up-to-date Chrome versions and subscribe to Google security advisories to apply patches promptly once available. 5) Employ application sandboxing and isolation techniques to limit the impact of potential browser compromises. 6) Conduct user awareness training to reduce insider threat risks and encourage reporting of suspicious activity. 7) Implement network segmentation to contain potential breaches originating from compromised endpoints. These measures go beyond generic advice by focusing on the local attack vector and high impact scope, emphasizing proactive detection and containment strategies tailored to the vulnerability's characteristics.
