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

This report details a critical security vulnerability, CVE-2025-3375, found in PCMan FTP Server 2.0.7. This vulnerability affects the CDUP command handler of the software, leading to a buffer overflow condition. The exploit can be triggered remotely, and its public disclosure potentially exposes any system running the affected version of the software to compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-3375
\nSeverity: Critical (CVSS: 7.3)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

PCMan FTP Server | 2.0.7<\/p>\n

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

The vulnerability is triggered when an attacker sends a specially crafted request to the CDUP command handler of the PCMan FTP Server. This request contains an oversized payload that exceeds the buffer capacity of the component, causing it to overflow. This overflow condition can then be exploited to execute arbitrary code or disrupt the normal operation of the software.<\/p>\n

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

Below is a conceptual example of how the vulnerability might be exploited. This is a simple FTP command that might be used to trigger the buffer overflow:<\/p>\n

USER anonymous\nPASS anonymous\nCDUP \/..\/..\/..\/..\/..\/..\/..\/..\/..\/..\/..\/..\/..\/..\/[BUFFER OVERFLOW PAYLOAD]<\/code><\/pre>\n
This example is purely conceptual and does not represent an actual exploit. The “[BUFFER OVERFLOW PAYLOAD]” would be replaced with a series of characters designed to overflow the buffer and potentially allow the execution of malicious code.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate the vulnerability, users are advised to apply vendor patches as soon as they become available. Until such a patch is released, users may employ Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as temporary mitigation measures against potential exploits.<\/p>\n","protected":false},"excerpt":{"rendered":"
