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

The vulnerability with ID CVE-2025-46739 is a serious security flaw that allows an unauthenticated user to retrieve account credentials via a brute-force attack without any rate limiting. This vulnerability is particularly dangerous due to its high severity score of 8.1, pointing to the potential for severe damage if exploited. Affected systems and users risk system compromise and data<\/a> leakage, making it a high-priority issue that demands immediate attention and mitigation.<\/p>\n

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

CVE ID: CVE-2025-46739
\nSeverity: High (8.1 CVSS)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a> and data leakage if successfully exploited<\/p>\n

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

Product | Affected Versions<\/p>\n

[Product 1] | [Version 1]
\n[Product 2] | [Version 2]<\/p>\n

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

The exploit works by allowing an unauthenticated user to perform a brute-force attack<\/a> on account credentials. Without any rate limiting in place, the attacker can send a high volume of requests<\/a> in a short amount of time. This allows the attacker to try a wide range of combinations until they find the correct credentials. Once the attacker has obtained these credentials, they can potentially compromise the system<\/a> or leak sensitive data.<\/p>\n

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

Here is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request<\/a> that the attacker could use:<\/p>\n

POST \/login HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"username\": \"admin\", \"password\": \"1234\" }<\/code><\/pre>\n
In this example, the attacker is trying to log in as the ‘admin’ user<\/a> with a simple password ‘1234. Without rate limiting in place, the attacker can quickly change these values to try different combinations. This is a simplistic example; in reality, the attacker would likely use a more complex algorithm to generate potential usernames and passwords<\/a>.<\/p>\n
Recommendations for Mitigation<\/strong><\/p>\n
The recommended solution to this vulnerability<\/a> is to apply the vendor-provided patch. This patch should address the vulnerability, preventing an attacker from exploiting<\/a> it.
\nIf the patch cannot be applied immediately, a temporary mitigation could be the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS). These systems can help detect and block suspicious activities such as multiple login<\/a> attempts from the same IP address.
\nHowever, they do not provide a complete solution, as they do not directly address the flaw in the system<\/a>. Therefore, it is strongly recommended to apply the vendor patch as soon as possible to fully secure the system against this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
