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

This report focuses on the CVE-2025-32459 vulnerability, an instance of CWE-88, that affects the Quantenna Wi-Fi chipset. This vulnerability is critical due to its potential to compromise systems and leak confidential data. As such, it poses a significant threat to any device or system implementing this chipset.<\/p>\n

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

CVE ID: CVE-2025-32459
\nSeverity: High (CVSS: 7.7)
\nAttack Vector: Local (AV:L)
\nPrivileges Required: None (PR:N)
\nUser Interaction: None (UI:N)
\nImpact: Potential system compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Quantenna Wi-Fi chipset | Up to and including version 8.0.0.28<\/p>\n

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

The vulnerability lies in the local control script, router_command.sh, specifically in the sync_time argument. This script does not properly neutralize argument delimiters, making it susceptible to command injection. An attacker can exploit this vulnerability to execute arbitrary commands on the system where the chipset is installed.<\/p>\n

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

Consider the following
\nconceptual<\/strong>
\n shell command, which an attacker might use to exploit this vulnerability:<\/p>\n

.\/router_command.sh sync_time; rm -rf \/ # This will delete all files in root directory<\/code><\/pre>\n
In this example, the attacker injects a malicious command (`rm -rf \/`) after the sync_time argument. If the script is executed with superuser privileges, this command will delete all files in the root directory.<\/p>\n
Mitigation<\/strong><\/p>\n
At the time of this report, no patch has been released by the vendor. However, a best practices guide for implementors of this chipset has been issued. As a temporary mitigation, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS). As always, it is crucial to monitor vendor communications for the release of a patch and to apply it as soon as possible.<\/p>\n","protected":false},"excerpt":{"rendered":"
