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

The cybersecurity world has once again been stirred by the discovery of a critical vulnerability, CVE-2025-5790, found in TOTOLINK X15’s firmware version 1.0.0-B20230714.1105. This vulnerability has severe implications for users of the affected device, as it potentially exposes systems to compromise and data leakage. The significance of this issue is underlined by its high CVSS Severity Score of 8.8, indicating that its successful exploitation could have a severe impact on the confidentiality, integrity, and availability of user data and systems<\/a>.<\/p>\n

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

CVE ID: CVE-2025-5790
\nSeverity: Critical (CVSS: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

TOTOLINK X15<\/a> | 1.0.0-B20230714.1105<\/p>\n

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

The exploit involves the manipulation of the ‘mac’ argument in the HTTP POST request<\/a> handler file \/boafrm\/formIpQoS. By supplying an excessively long string to this argument, an attacker can trigger a buffer overflow<\/a>. This overflow can potentially allow the attacker to execute arbitrary code<\/a> or cause the system to crash, leading to a denial of service.<\/p>\n

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

Here’s a conceptual example of how an HTTP POST request could potentially exploit this vulnerability<\/a>:<\/p>\n

POST \/boafrm\/formIpQoS HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nmac=aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz<\/code><\/pre>\n
In this example, the ‘mac’ parameter is filled with a string that exceeds the expected length, potentially leading<\/a> to a buffer overflow.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of TOTOLINK X15<\/a> version 1.0.0-B20230714.1105 are advised to apply the vendor-provided patch as soon as it’s available. As a temporary mitigation, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) is recommended to monitor and block suspicious activities. It’s also advisable to restrict network access to the affected devices and not expose<\/a> them to the internet until a patch is applied.<\/p>\n","protected":false},"excerpt":{"rendered":"
