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

The cybersecurity landscape is continually evolving, with new vulnerabilities being discovered on a regular basis. One such vulnerability, identified as CVE-2025-6164, has been recently found in TOTOLINK A3002R 4.0.0-B20230531.1404. This critical security<\/a> flaw affects the HTTP POST Request Handler component, specifically in the \/boafrm\/formMultiAP file. Its severity and potential for exploitation make this vulnerability<\/a> particularly concerning.
\nThe risks are significant due to the potential for system<\/a> compromise or data leakage. Any entity using the affected versions of the TOTOLINK<\/a> A3002R should take immediate steps to mitigate the risk and protect their system integrity and data confidentiality.<\/p>\n

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

CVE ID: CVE-2025-6164
\nSeverity: Critical (CVSS 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise or data<\/a> leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

TOTOLINK A3002R | 4.0.0-B20230531.1404<\/p>\n

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

The vulnerability lies in the manipulation of the ‘submit-url’ argument within the HTTP POST Request Handler of the TOTOLINK<\/a> A3002R. By manipulating this argument, the attacker can trigger a buffer overflow<\/a> condition. Buffer overflow<\/a> exploits typically involve the input of an amount of data that exceeds the buffer’s capacity, which then overwrites adjacent memory locations. In this case, it can lead to a system compromise or potential<\/a> data leakage.<\/p>\n

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

Here’s a conceptual representation of an HTTP POST request that might exploit this vulnerability<\/a>:<\/p>\n

POST \/boafrm\/formMultiAP HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nsubmit-url=...[malicious_buffer_overflow_payload]<\/code><\/pre>\n
In the above example, the ‘submit-url’ argument is appended with a malicious payload designed to exploit the buffer overflow vulnerability<\/a>.<\/p>\n
Recommended Mitigation<\/strong><\/p>\n
To mitigate this vulnerability<\/a>, TOTOLINK A3002R users should apply the vendor patch as soon as it becomes available. In the meantime, users can employ a Web<\/a> Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. Regular monitoring for any unusual activity, and having robust incident response procedures in place, are also essential for limiting potential damage.<\/p>\n","protected":false},"excerpt":{"rendered":"
