FTP Command Injection in Konqueror 3.3.1

IdentifiersCVE-2004-1165CWE-77

Konqueror 3.3.1 is vulnerable to FTP command injection via specially crafted ftp:// URLs containing a URL-encoded newline (%0a) before an FTP command. This allows an attacker to inject arbitrary FTP commands into the FTP session established by Konqueror, such as the PORT command, potentially manipulating the FTP connection or server behavior.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker can execute arbitrary FTP commands in the context of the user's FTP session, which may allow for data exfiltration, manipulation of files, or leveraging the client as a pivot for further attacks, depending on the FTP server's configuration and the commands injected.

Mitigation

If you can’t patch tonight, do this now.

As a temporary mitigation, avoid clicking on or using untrusted ftp:// URLs, and consider disabling FTP protocol handling in Konqueror until a patch is applied.

Remediation

Patch, then assume compromise.

Upgrade to a version of Konqueror where this vulnerability is patched. Ensure that the application properly sanitizes and validates input in URLs before passing them to the FTP session handler.
