Vulnerability Note VU#610904

Oracle Internet Directory LDAP Daemon does not check write permissions properly

Original Release date: 09 Jul 2001 | Last revised: 09 Jul 2001

Overview

The Oracle LDAP Daemon (oidldapd version 2.1.1.1), which ships with Oracle version 8i for Linux version 8.1.7, does not check write permissions properly. This can allow a local user to delete or write to any file on the system.

Description

The Oracle LDAP Daemon (oidldapd version 2.1.1.1) does not check write permissions properly. It generates log files in a directory (ldaplog) that has world-writable permissions. This can be used by local users to erase log files. In conjunction with a symlink attack, a local user can write to or delete any file on the local machine.

Impact

A local user can write to or delete any file on the system.

Solution

Oracle encourages all Linux directory developers to download the upcoming production version of Oracle Internet Directory, v2.1.1, part of the Oracle 8.1.7 (8i Release 3) server media pack, from http://technet.oracle.com/.

Use chmod to set the file permissions to 710 for the oidldapd and oidmon executables. This will restrict access to privileged users only.
