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

A critical vulnerability, CVE-2025-45985, has been discovered in several models of Blink routers. This vulnerability exposes a significant risk to both individuals and businesses, as it could potentially lead to system compromise or data leakage. Blink routers are widely used around the globe, hence the discovery of this vulnerability is of considerable concern to the cybersecurity community<\/a>.
\nThe vulnerability lies within the bs_SetSSIDHide function and is classified as a command<\/a> injection vulnerability. Command injection vulnerabilities are particularly dangerous, as they allow attackers to execute arbitrary<\/a> commands on the host operating system, which can lead to a full system compromise.<\/p>\n

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

CVE ID: CVE-2025-45985
\nSeverity: Critical (CVSS: 9.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise or data<\/a> 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 vulnerability is a command injection<\/a> flaw within the bs_SetSSIDHide function. This function is vulnerable because it fails to properly sanitize user-supplied input<\/a>. An attacker can leverage this flaw to inject and execute arbitrary shell commands on the host system, potentially leading to a complete system<\/a> compromise or data leakage.<\/p>\n

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

Below is a conceptual example of exploiting this vulnerability. The attacker sends a malicious payload via an HTTP POST request to the vulnerable<\/a> endpoint.<\/p>\n

POST \/bs_SetSSIDHide HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"ssid\": \"; rm -rf \/;\" }<\/code><\/pre>\n
In this example, the attacker is injecting a shell command (`rm -rf \/`) which, if executed, will delete all files<\/a> on the target system. Please note that this is a highly destructive command and is used here purely for illustrative purposes.<\/p>\n
Mitigation<\/strong><\/p>\n
It is recommended to apply the security patch provided by the vendor as soon as possible. In case the patch cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. They should be configured to detect and block command injection<\/a> attempts.<\/p>\n","protected":false},"excerpt":{"rendered":"
