CVE-1999-1267: KDE kfm arbitrary file modification via insecure TCP server

CVE-1999-1267 · Severity: medium · CVSS 5 · Published 1997-05-05

The KDE file manager (kfm) contains a security flaw in how it handles file operations. Because it uses an unsecured network connection to process commands, a remote attacker could potentially modify or overwrite files on a user's system. This could lead to unauthorized access or the corruption of important configuration files.

Technologies: Kde. Vendors: Kde.

Technical details

The KDE file manager (kfm) implements a TCP server to facilitate communication between desktop modules. This server lacks authentication and proper access controls, allowing any network-reachable attacker to send commands to the service. Specifically, an attacker can issue 'copy' commands to the server. If an attacker can place a malicious file on the target system (e.g., via anonymous FTP), they can then instruct kfm to copy that file into sensitive locations, such as a user's .rhosts file, to gain further access. The recommended fix is to migrate the communication mechanism from TCP sockets to AF_UNIX sockets with restricted file permissions.
