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

The vulnerability CVE-2025-44652 involves a configuration flaw in Netgear RAX30 V1.0.10.94_3, a widely-used router. This vulnerability allows potential attackers to instigate Denial of Service (DoS) attacks by exploiting the USERLIMIT_GLOBAL option which is set to 0 in several bftpd-related configuration files. This vulnerability is significant due to its potential to disrupt networks and services, with the possibility for system compromise and data leakage.<\/p>\n

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

CVE ID: CVE-2025-44652
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Disruption of network services, potential system compromise, and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Netgear RAX30 | V1.0.10.94_3<\/p>\n

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

The vulnerability exists in the bftpd-related configuration files where the USERLIMIT_GLOBAL option is set to 0. This setting means there is no limit to the number of users that can connect to the bftpd server. An attacker can exploit this by connecting an unlimited number of users to the server, thereby exhausting system resources and causing a Denial of Service. There is also a concern that this could lead to system compromise or data leakage.<\/p>\n

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

While the following code is conceptual and not an actual exploit script, it helps illustrate the vulnerability:<\/p>\n

#!\/bin\/bash\n# Script to open unlimited connections to the bftpd server\nwhile true\ndo\nnc target.example.com 21 &\ndone<\/code><\/pre>\n
This script connects to the bftpd server on the target machine an unlimited number of times, which could potentially lead to a Denial of Service due to the unrestricted user limit. It’s important to note that actual exploitation may involve more complex scripts and techniques, and this example is simplified for illustrative purposes.<\/p>\n
Mitigation<\/strong><\/p>\n
As a mitigation measure, it is recommended to apply the vendor patch when it becomes available. Until then, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regularly updating and patching systems can also help prevent exploitation of such vulnerabilities.<\/p>\n","protected":false},"excerpt":{"rendered":"
