Overview<\/strong><\/p>\n

This report presents a detailed analysis of the CVE-2025-45586 vulnerability, a critical flaw in Audi’s UTR 2.0 Universal Traffic Recorder. This vulnerability affects all users of the software and poses a significant cybersecurity threat due to its potential exploitation leading to system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-45586
\nSeverity: High (CVSS: 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Arbitrary file overwrite leading to potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Audi UTR 2.0 Universal Traffic Recorder | 2.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from a flaw in the software’s handling of PUT requests. An attacker can craft a malicious PUT request that can overwrite files in the system. This can potentially lead to system compromise if critical system files are overwritten, or to data leakage if data files are overwritten with attacker-controlled data.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited. This example demonstrates a malicious HTTP PUT request sent to the vulnerable endpoint.<\/p>\n

PUT \/vulnerable\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"file_path\": \"\/critical\/system\/file\", \"content\": \"malicious_content\" }<\/code><\/pre>\n
In this example, the PUT request targets a critical system file for overwrite, replacing its content with malicious data.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are advised to apply the latest patch from the vendor as soon as possible. As a temporary mitigation, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to block or alert on malicious PUT requests. However, these measures do not remove the vulnerability but merely reduce the risk of exploitation.<\/p>\n","protected":false},"excerpt":{"rendered":"
