Product | Affected Versions<\/p>\n

Linksys E5600 | v1.1.0.26<\/p>\n

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

The CVE-2025-45491 vulnerability exists due to the improper<\/a> sanitization of the username parameter in the runtime.ddnsStatus DynDNS function. This allows an attacker to inject arbitrary commands<\/a> into the system through this parameter, which will then be executed with high-level privileges. The attacker can exploit this vulnerability remotely<\/a> over a network, without requiring any user interaction or privileges.<\/p>\n

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

Below is a conceptual example of how the vulnerability might be exploited. An attacker sends a malicious HTTP request with the injected command<\/a> in the username parameter:<\/p>\n

POST \/runtime.ddnsStatus HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"username\": \"; [insert malicious command here]\" }<\/code><\/pre>\n
In this example, the semicolon allows the attacker to inject a new command<\/a> into the username parameter, which is then executed by the system.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the patch provided by the vendor as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. This will prevent the execution of malicious commands<\/a> and provide an additional layer of security until a permanent solution can be implemented.<\/p>\n","protected":false},"excerpt":{"rendered":"
