Exploited in the wild: not listed in CISA KEV
EPSS: 7.1% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2005-01-10 · updated 2026-06-16

Description

The addslashes function in PHP 4.3.9 does not properly escape a NULL (/0) character, which may allow remote attackers to read arbitrary files in PHP applications that contain a directory traversal vulnerability in require or include statements, but are otherwise protected by the magic_quotes_gpc mechanism. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Affected products

PHP: 4.3.6, 4.3.7, 4.3.8, 4.3.9, 5.0-rc1, 5.0-rc2 (+4)
