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

In this blog post, we will examine the critical vulnerabilities discovered in several models of Blink routers, identified as CVE-2025-45987. These vulnerabilities can lead to command injection attacks, which have the potential to compromise the system or lead to data leakage. The affected routers are widely used in both residential and commercial environments, making this a significant issue of concern for many. With a CVSS severity score of 9.8, these vulnerabilities must be addressed immediately to prevent potential<\/a> security breaches.<\/p>\n

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

CVE ID: CVE-2025-45987
\nSeverity: Critical with a CVSS score of 9.8
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Blink BL-WR9000 | V2.4.9
\nBlink BL-AC2100_AZ3 | V1.0.4
\nBlink BL-X10_AC8 | v1.0.5
\nBlink BL-LTE300 | v1.2.3
\nBlink BL-F1200_AT1 | v1.0.0
\nBlink BL-X26_AC8 | v1.2.8
\nBlink BLAC450M_AE4 | v4.0.0
\nBlink BL-X26_DA3 | v1.2.7<\/p>\n

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

The vulnerabilities stem from improper validation<\/a> of the ‘dns1’ and ‘dns2’ parameters in the ‘bs_SetDNSInfo’ function. This lack of validation allows an attacker to inject and execute arbitrary<\/a> commands on the system. The attacker can exploit this vulnerability remotely<\/a> over the network without requiring any authentication or user interaction.<\/p>\n

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

To illustrate the vulnerability, consider the following hypothetical HTTP request<\/a>. In this example, the attacker sends a malicious POST request to the router’s web interface<\/a>, injecting arbitrary commands into the ‘dns1’ and ‘dns2’ parameters.<\/p>\n

POST \/bs_SetDNSInfo HTTP\/1.1\nHost: target_blink_router\nContent-Type: application\/x-www-form-urlencoded\ndns1=8.8.8.8;%20malicious_command&dns2=8.8.4.4;%20malicious_command<\/code><\/pre>\n
Mitigation<\/strong><\/p>\n
Users of the affected Blink routers should immediately apply the patches provided by the vendor. If a patch is not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to block or alert on suspicious DNS settings manipulation, thereby preventing exploitation of this vulnerability<\/a>.
\nRemember, regular patching and system updates are essential to maintain a strong security<\/a> posture. Ignoring such vulnerabilities can expose your network to potential compromises and data<\/a> breaches. Stay updated, stay secure.<\/p>\n","protected":false},"excerpt":{"rendered":"
