Published Jan 18, 2011

MEDIUMCVSS 2.0
EPSS 5.36%
Description
PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the file_exists function.
