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

The Common Vulnerabilities and Exposures (CVE) system has identified a significant security flaw in Kapsch TrafficCom RIS-9160 & RIS-9260 Roadside Units (RSUs). These systems, which are used to manage traffic flow and provide roadside communication, were discovered to lack secure password requirements for its BIOS Supervisor and User accounts. This lack of security places the systems, and potentially the data<\/a> they manage, at severe risk. Given how integral these systems are to traffic management and safety, the potential consequences of this vulnerability<\/a> are substantial and wide-reaching.<\/p>\n

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

CVE ID: CVE-2025-25737
\nSeverity: Critical (9.8\/10.0)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Kapsch TrafficCom<\/a> RIS-9160 | v3.2.0.829.23
\nKapsch TrafficCom<\/a> RIS-9260 | v3.8.0.1119.42, v4.6.0.1211.28<\/p>\n

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

The vulnerability exists due to the lack of secure<\/a> password requirements for the BIOS Supervisor and User accounts in the aforementioned Kapsch TrafficCom RSUs. This allows attackers to perform a bruteforce attack, which involves trying every possible password combination until the correct one is found. Once the attacker has gained access<\/a> to these accounts, they can potentially compromise the system or leak data.<\/p>\n

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

This is a conceptual example of a bruteforce attack using a Python script:<\/p>\n

import itertools\ndef bruteforce(charset, maxlength):\nreturn (''.join(candidate)\nfor candidate in itertools.chain.from_iterable(itertools.product(charset, repeat=i)\nfor i in range(1, maxlength + 1)))\nfor attempt in bruteforce(\"ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789\", 10):\n# Insert code here to try to login with 'attempt' as the password\npass<\/code><\/pre>\n
In this example, the Python script generates all possible combinations of uppercase letters and numbers up to a length of 10. The script then attempts to log in with each generated combination.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of the affected Kapsch TrafficCom RSUs are recommended to apply the vendor patch as soon as it’s available. As a temporary mitigation, users may also use a Web Application Firewall (WAF) or Intrusion Detection System (IDS). These systems can help to detect and prevent bruteforce attacks by monitoring network traffic and alerting or blocking any suspicious activity.
\nHowever, these measures should only be considered as temporary solutions. Applying the vendor patch should be the priority to ensure the vulnerability is completely addressed<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
