CVE-2024-48208 Scanner

The Pure-FTPd software is widely used by organizations for its secure FTP server capabilities. It is deployed across multiple platforms, providing essential file transfer services. Administrators and IT departments rely on it for managing file exchanges in both internal and external environments. Given its robustness and reliability, it finds applications in hosting services and data management sectors. Pure-FTPd's user-friendly interface and support for modern security features make it a popular choice for secure data transmissions. Businesses and data centers favor it for its performance and the assurance of secure file handling.

This vulnerability in Pure-FTPd specifically involves a buffer overflow issue. An out-of-bounds read in the domlsd() function within the ls.c file can be exploited. Attackers could leverage this to execute arbitrary code on systems running vulnerable versions of Pure-FTPd. The ease of access over the network makes this vulnerability particularly concerning. Exploitation does not require authentication, increasing its susceptibility to attacks. Accordingly, the CVE-2024-48208 vulnerability has been classified with a high severity rating due to its potential impact.

Technically, the vulnerability involves improper handling of data within the domlsd() function. The flaw arises from inadequate boundary checks on buffer memory allocations. This oversight allows attackers to trigger an out-of-bounds read, bypassing conventional security protocols. The vulnerability exists across versions prior to 1.0.52 of Pure-FTPd. Exploitable via network connections on FTP port 21, it emphasizes the criticality of safeguards within the system. Specifically, the vector used can manipulate input data flow, compromising data integrity.

If exploited, this vulnerability could lead attackers to gain arbitrary code execution capabilities. This scenario could result in unauthorized access and control over affected systems. Attackers might use it to cease operations, manipulate data, or install malicious software. Over time, this may compromise system integrity, resulting in potential data loss or exfiltration. The impact extends to user privacy, exposing sensitive information to interception. Business operations reliant on Pure-FTPd for file transfers face a significant threat under this vulnerability.
