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

The Common Vulnerabilities and Exposures (CVE) system recently identified a severe security vulnerability, dubbed CVE-2025-28030, in TOTOLINK A810R V4.1.2cu.5182_B20201026. This vulnerability poses a significant risk to businesses and individuals using the TOTOLINK A810R router, as it could potentially allow malicious actors to compromise the system or cause data leakage. As such, understanding this vulnerability and implementing necessary mitigation measures is crucial to safeguarding your network and data<\/a>.<\/p>\n

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

CVE ID: CVE-2025-28030
\nSeverity: High (CVSS: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential data<\/a> leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

TOTOLINK A810R<\/a> | V4.1.2cu.5182_B20201026<\/p>\n

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

The vulnerability in TOTOLINK<\/a> A810R arises due to a stack overflow condition in the setParentalRules function. Specifically, the startTime and endTime parameters in the function can be manipulated to exceed the allocated memory<\/a> space, causing an overflow. This overflow can be exploited by an attacker to execute arbitrary code on the router, leading to system compromise and potentially<\/a> data leakage.<\/p>\n

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

The following conceptual example demonstrates how an attacker might exploit<\/a> this vulnerability. It involves sending a malicious HTTP request to the vulnerable router<\/a>.<\/p>\n

POST \/setParentalRules HTTP\/1.1\nHost: \nContent-Type: application\/json\n{\n\"startTime\": \"10000000000000000000000000...\",\n\"endTime\": \"10000000000000000000000000...\"\n}<\/code><\/pre>\n
In this example, the startTime and endTime parameters are filled with an overly large value, triggering the stack overflow vulnerability<\/a>.<\/p>\n
Mitigation and Remediation<\/strong><\/p>\n
The best course of action to mitigate this vulnerability<\/a> is to apply the vendor-provided patch as soon as it is available. If the patch is not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can monitor and block potentially<\/a> malicious activity, offering some degree of protection until the patch can be applied.
\nRemember to always keep your systems updated, perform regular security audits, and follow best security practices to minimize the chances of your system being affected by such vulnerabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
