• Exploited in the wild: not listed in CISA KEV
• EPSS: 4.8% probability of exploitation in the next 30 days

Description

The Foreign Function Interface (ffi) extension in PHP 5.0.5 does not follow safe_mode restrictions, which allows context-dependent attackers to execute arbitrary code by loading an arbitrary DLL and calling a function, as demonstrated by kernel32.dll and the WinExec function. NOTE: this issue does not cross privilege boundaries in most contexts, so perhaps it should not be included in CVE.

Affected products

• PHP: 5.0.5
