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

The cybersecurity landscape is littered with countless vulnerabilities and threats, but every so often, a particularly serious flaw garners increased attention and concern. Such is the case with the recently discovered CVE-2025-9087 vulnerability. This vulnerability exists in Tenda<\/a> AC20 16.03.08.12, specifically affecting the function set_qosMib_list of the file \/goform\/SetNetControlList within the SetNetControlList Endpoint component. The exploitation of this vulnerability can lead to a stack-based buffer overflow<\/a>, a type of security issue that can have severe consequences, including potential system compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-9087
\nSeverity: High, CVSS score of 8.8
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: The successful exploitation of this vulnerability could result in a system compromise or data<\/a> leakage.<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda AC20<\/a> | 16.03.08.12<\/p>\n

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

This vulnerability arises from a lack of proper input validation<\/a> in the set_qosMib_list function of the file \/goform\/SetNetControlList. An attacker can exploit the vulnerability by manipulating the argument list of the function, triggering a stack-based buffer overflow<\/a>. Given that the vulnerability can be exploited remotely<\/a> and does not require any user interaction, it presents a significant risk. The exploit has been disclosed to the public, making systems running the affected version of Tenda AC20 more vulnerable<\/a> to potential attacks.<\/p>\n

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

Here is a conceptual example of how the vulnerability might be exploited. This is a hypothetical HTTP request that includes a malicious payload designed to trigger the buffer overflow<\/a>:<\/p>\n

POST \/goform\/SetNetControlList HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"set_qosMib_list\": \"malicious_payload\" }<\/code><\/pre>\n
Please note that this is a conceptual example and should not be tried on a live system.
\nTo mitigate the risk associated with this vulnerability<\/a>, vendors are advised to apply the available patches. In circumstances where patching is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these should not be considered long-term solutions, and patching should be prioritized as soon as feasible.<\/p>\n","protected":false},"excerpt":{"rendered":"
