CWE-624 可执行体正则表达式错误
Executable Regular Expression Error
结构: Simple
Abstraction: Base
状态: Incomplete
被利用可能性: unkown
基本描述
The product uses a regular expression that either (1) contains an executable component with user-controlled inputs, or (2) allows a user to enable execution by inserting pattern modifiers.
扩展描述
Case (2) is possible in the PHP preg_replace() function, and possibly in other languages when a user-controlled input is inserted into a string that is later parsed as a regular expression.

可能的缓解方案
Implementation
策略:
The regular expression feature in some languages allows inputs to be quoted or escaped before insertion, such as \Q and \E in Perl.
