CVE-2006-5178
Last modified
CVE-2006-5178 is a vulnerability of currently unknown severity. Race condition in the symlink function in PHP 5.1.6 and earlier allows local users to bypass the open_basedir restriction by using a combination of symlink, mkdir, and unlink functions to change the file path after the open_basedir check and before the file is opened by the underlying system, as demonstrated by symlinking a symlink into a subdirectory, to point to a parent directory via .. (dot dot) sequences, and then unlinking the resulting symlink.. EPSS estimates a 0.64% chance of exploitation in the next 30 days.
