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

This blog post provides an in-depth analysis of the CVE-2025-46633 vulnerability, a significant cybersecurity threat affecting the Tenda RX2 Pro 16.03.30.14 web management portal. This vulnerability involves the cleartext transmission of sensitive information, specifically the symmetric AES key that is essential for decrypting traffic between the client and server. This issue poses a serious risk to all users of the Tenda RX2<\/a> Pro system because an attacker could potentially decrypt traffic and gain unauthorized access to sensitive data.<\/p>\n

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

CVE ID: CVE-2025-46633
\nSeverity: High (CVSS score 8.2)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise and sensitive data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda RX2<\/a> Pro | 16.03.30.14<\/p>\n

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

The exploit leverages the cleartext transmission<\/a> of the symmetric AES key during successful authentication. The IV, which is always “EU5H62G9ICGRNI43”, can be captured from the collected and\/or observed traffic. This allows an attacker to decrypt the traffic between the client and server, potentially leading to system<\/a> compromise and data leakage.<\/p>\n

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

The vulnerability could potentially<\/a> be exploited through a simple network sniffing attack. Below is a simplified representation of how an attacker might capture the cleartext AES key in transit:<\/p>\n

# Listen on the network interface for packets involving the targeted IP\ntcpdump -i eth0 'host targetIP' -w capture.pcap\n# Use a tool like Wireshark to analyze the capture\nwireshark capture.pcap\n# Look for packets containing the AES key in cleartext following successful authentication<\/code><\/pre>\n
Please note that this is a conceptual example and does not represent a real-world exploit.<\/p>\n
Mitigation and Recommendations<\/strong><\/p>\n
The most direct mitigation for this vulnerability<\/a> is to apply the vendor patch once it becomes available. However, as a temporary measure, you can also use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious traffic. Regular patching and updating of systems as well as monitoring network traffic<\/a> for anomalies are also recommended best practices.
\nIn conclusion, the CVE-2025-46633 vulnerability represents a significant security threat to users<\/a> of the affected product. It is highly recommended to apply the appropriate mitigations as soon as possible to protect your systems and data<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
