Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists in the phar_do_404() and phar_do_403() functions due to insufficient sanitization of user-supplied data processed by the phar_do_404() and phar_do_403() functions, as defined in the ext/phar/phar_object.c source code file. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

The vulnerability exists due to an incomplete fix for CVE-2018-5712.

The vulnerability is addressed in the following versions: 5.6.36, 7.1.17, 7.2.5 and 7.0.30.
