New! Plugin Severity Now Using CVSS v3

Synopsis

An application installed on the remote host is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is 7.2.x prior to 7.2.16. It is, therefore, affected by multiple vulnerabilities:

- Uninitialized reads in the EXIF component of PHP due to the mishandling of data in exif_process_IFD_in_MAKERNOTE, and exif_process_IFD_in_TIFF. (CVE-2019-9638, CVE-2019-9639, CVE-2019-9641)

- An invalid read in the EXIF component of PHP due to a mishandling of data in exif_process_SOFn. (CVE-2019-9640)

- An access control bypass vulnerability exists due to the way rename() is implemented. This could allow unauthorized users to access data they otherwise would not have access to (CVE-2019-9637).

Solution

Upgrade to PHP version 7.2.16 or later.
