CVE-2007-1742 Detail

Description

suexec in Apache HTTP Server (httpd) 2.2.3 uses a partial comparison for verifying whether the current directory is within the document root, which might allow local users to perform unauthorized operations on incorrect directories, as demonstrated using "html_backup" and "htmleditor" under an "html" directory. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root."

Official Statement from Red Hat (04/19/2007)

These attacks are reliant on an insecure configuration of the server - that the user the server runs as has write access to the document root. The suexec security model is not intented to protect against privilege escalation in such a configuration
