This script is vulnerable to command injection, an instance of CWE-88 or &#8220;Improper Neutralization of Argument Delimiters in a Command (&#8216;Argument Injection&#8217;).&#8221; This vulnerability lets attackers execute arbitrary commands in the context of the script. Since the script doesn&#8217;t properly neutralize argument delimiters, an attacker can inject commands that the system runs with the same privileges as the script itself.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2324367895\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following is a conceptual example of how this vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">.\/router_command.sh &#039;; rm -rf \/&#039; # This is a destructive command. DO NOT run.<\/code><\/pre>\n<p>In this example, the semicolon acts as a command delimiter, allowing the attacker to inject a secondary command (`rm -rf \/`) that the system runs as if it were part of the original script. This particular command would delete all files within the system, demonstrating the potential severity of this vulnerability.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>As of the time of this report, the vendor appears to have not yet patched this vulnerability. However, they&#8217;ve released a best practices guide for implementors of the chipset. In the interim period before a patch is available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate potential attacks. Once the vendor provides a patch, it should be applied immediately to all affected systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report addresses a significant vulnerability, CVE-2025-32455, found within the Quantenna Wi-Fi chipset.
