Release Date: 2004-02-09
Critical: Less critical
Impact: Security Bypass, Exposure of sensitive information
Where: From remote
Software: PHP 4.3.x
Description:
A vulnerability has been identified in PHP, potentially allowing malicious people to view sensitive data or bypass an administrative restriction.
The problem arises on systems serving multiple virtual hosts using the Apache web server. Administratively configured settings from one virtual host may be applied (leaked) to other virtual hosts if the same Apache child process is used to access the different virtual hosts.
This can reportedly be exploited to view the source of PHP files, overwrite "register_globals" settings and more. Other vulnerabilities may potentially also be exploited via this issue.
The vulnerability has been reported in PHP version 4.3.4 and prior.
Solution:
There is no effective solution.
Provided and/or discovered by:
