Synopsis

PHP 7.3.x < 7.3.23 Multiple Vulnerabilities

Description

According to its self-reported version number, the version of PHP running on the remote web server is 7.2.x prior to 7.2.34, 7.3.x prior to 7.3.23 or 7.4.x prior to 7.4.11. It is, therefore, affected by multiple vulnerabilities:

 - When AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data. (CVE-2020-7069)

 - When PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. (CVE-2020-7070)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 7.3.23 or later.
