Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2016-2512)

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

The weakness exists in the utils.http.is_safe_url function due to insufficient sanitization of user-supplied data. 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.


2) Timing attack (CVE-ID: CVE-2016-2513)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the password hasher in contrib/auth/hashers.py due to creating a timing difference between a login request for a user with a password encoded in an older number of iterations and login request for a nonexistent user. A remote attacker can enumerate users via a timing attack involving login requests.
