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

A critical vulnerability, identified as CVE-2025-7117, has been discovered in UTT HiPER 840G, affecting versions up to 3.1.1-190328. This vulnerability is significant as it directly impacts the \/goform\/websWhiteList file and can be exploited remotely. The consequences of a successful exploit could lead to system<\/a> compromise or data leakage, potentially causing severe damage to the affected organization. As the exploit has been disclosed publicly, the risk of exploitation has significantly increased, making it vital for affected users to take immediate action.<\/p>\n

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

CVE ID: CVE-2025-7117
\nSeverity: Critical (8.8 CVSS Score)
\nAttack Vector: Remote, network-based
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, potential data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

UTT HiPER<\/a> 840G | up to 3.1.1-190328<\/p>\n

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

The exploit works by manipulating the “addHostFilter” argument in the \/goform\/websWhiteList file<\/a>. An attacker sends a specially crafted request that can overflow the buffer<\/a>, leading to unexpected behavior in the software. This could allow an attacker to execute arbitrary code<\/a>, modify system configurations, or gain unauthorized access to sensitive data.<\/p>\n

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

Here is a conceptual example of how the vulnerability might be exploited. This is a pseudo HTTP request that sends a malicious payload to the vulnerable<\/a> endpoint.<\/p>\n

POST \/goform\/websWhiteList HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"addHostFilter\": \"A\"*8000\n}<\/code><\/pre>\n
Please note that this is merely a conceptual example and not an actual exploit code. It is meant to demonstrate the vulnerability, not provide a guide for malicious activities.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Affected users should immediately apply the patch provided by the vendor. In case the patch is not available, users should implement a Web Application<\/a> Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Such solutions can help detect and block exploit attempts, reducing the risk of system<\/a> compromise or data leakage.<\/p>\n","protected":false},"excerpt":{"rendered":"
