Synopsis

PHP 7.3.x < 7.3.29 Multiple Vulnerabilities

Description

According to its self-reported version number, the version of PHP installed on the remote host is 7.3.x prior to 7.3.29, 7.4.x prior to 7.4.21, or 8.x prior to 8.0.8. It is, therefore, affected by multiple vulnerabilities:

- Server-Side Request Forgery (SSRF) bypass in FILTER_VALIDATE_URL. (CVE-2021-21705)

- Bugs in pdo_firebase module allow a malicious firebase server or man-in-the-middle attacker to crash PHP. (CVE-2021-21704)

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 7.3.29 or later.
