Gallery: Arbitrary command execution Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200409-05 (Gallery: Arbitrary command execution) The upload handling code in Gallery places uploaded files in a temporary directory. After 30 seconds, these files are deleted if they are not valid images. However, since the file exists for 30 seconds, a carefully crafted script could be initiated by the remote attacker during this 30 second timeout. Note that the temporary directory has to be located inside the webroot and a possible hacker needs to have upload rights either as an authenticated user or via "EVERYBODY". Impact A possible hacker could run arbitrary code as the user running PHP. Workaround There are several workarounds to this vulnerability: Make sure that your temporary directory is not contained in the webroot by default it is located outside the webroot. Disable upload rights to all albums for "EVERYBODY" upload is disabled by default. Disable debug and dev mode these settings are disabled by default. Disable permit_url_fopen in php.ini.
