Weakness Name
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Description
The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in "require," "include," or similar functions.
In certain versions and configurations of PHP, this can allow an attacker to specify a URL to a remote location from which the product will obtain the code to execute. In other cases in association with path traversal, the attacker can specify a local file that may contain executable statements that can be parsed by PHP.
Common Consequences
Scope: Integrity, Confidentiality, Availability
Impact: Execute Unauthorized Code or Commands
Notes: The attacker may be able to specify arbitrary code to be executed from a remote location. Alternatively, it may be possible to use normal program behavior to insert php code into files on the local machine which can then be included and force the code to execute since php ignores everything in the file except for the content between php specifiers.
