Detailsinfo

A vulnerability was found in PHP up to 5.5.31/5.6.17/7.0.2 (Programming Language Software). It has been classified as critical. This affects the function stream_get_meta_data of the component File Upload. The manipulation as part of a Return Value leads to a input validation vulnerability (Metadata). CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker.
