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

In this post, we are going to delve into the details of a serious cybersecurity vulnerability, CVE-2025-46634, affecting users of the Tenda RX2 Pro web management portal. This vulnerability can potentially allow an unauthenticated attacker to gain access to the web management portal by collecting credentials from observed or collected traffic. Despite implementing encryption, the system transmits the hash of users’ passwords in cleartext, a loophole that can be exploited by malicious<\/a> entities. This vulnerability matters because it can lead<\/a> to a full-scale system compromise or data leakage, posing a significant risk to both individual users and organizations relying on this portal.<\/p>\n

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

CVE ID: CVE-2025-46634
\nSeverity: High (CVSS: 8.2)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or 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 vulnerability lies in the Tenda<\/a> RX2 Pro web management portal’s handling of user authentication. Despite implementing encryption, the system initially transmits the hash of the user’s password<\/a> in cleartext. An unauthenticated attacker<\/a> can observe or collect this cleartext traffic to retrieve the password hash. Since the hash is transmitted in cleartext, it can be easily collected by malicious entities. This hash can then be replayed to authenticate to the web management portal<\/a>, allowing the attacker access to the system.<\/p>\n

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

Here’s a conceptual example of how an attacker might exploit this vulnerability<\/a>:<\/p>\n

GET \/login HTTP\/1.1\nHost: vulnerable-portal.example.com\nUser-Agent: Any standard web browser\nResponse:\nHTTP\/1.1 200 OK\nServer: vulnerable-portal\nContent-Type: text\/html\nSet-Cookie: JSESSIONID=1234567890; path=\/; HttpOnly\nPassword-Hash: e99a18c428cb38d5f260853678922e03<\/code><\/pre>\n
In this example, the attacker observes the traffic and collects the `Password-Hash` from the response headers. This hash can then be used to replay the authentication process, granting the attacker access to the web management<\/a> portal.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users of the affected versions of Tenda RX2<\/a> Pro are advised to apply the vendor-supplied patch as soon as possible. As a temporary mitigation measure, users can employ a Web Application<\/a> Firewall (WAF) or an Intrusion Detection System (IDS) to monitor, detect and prevent any suspicious activities. However, these are not long-term solutions and users should update their systems to the patched versions<\/a> at the earliest.<\/p>\n","protected":false},"excerpt":{"rendered":"
