Description
Weblate is a web based localization tool. An open redirect exists in versions 5.13.2 and below via the redir parameter on .within.website when Weblate is configured with Anubis and REDIRECT_DOMAINS is not set. An attacker can craft a URL on the legitimate domain that redirects a victim to an attacker-controlled site. The redirect can also be used to initiate drive-by downloads (redirecting to a URL that serves a malicious file), increasing the risk to end users. This issue is fixed in version 5.13.3.

Executive Summary

This vulnerability is an open redirect in Weblate versions 5.13.2 and below. It occurs via the 'redir' parameter on .within.website when Weblate is configured with Anubis and the REDIRECT_DOMAINS setting is not configured. An attacker can craft a URL on the legitimate domain that redirects users to an attacker-controlled site, potentially leading to malicious activities such as drive-by downloads.

Impact Analysis

The vulnerability can impact you by allowing attackers to redirect users from a legitimate Weblate domain to malicious sites. This can lead to drive-by downloads where users might unknowingly download malicious files, increasing the risk of malware infection and compromise of user systems.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade Weblate to version 5.13.3 or later, where the open redirect issue is fixed. Additionally, ensure that the REDIRECT_DOMAINS setting is properly configured to restrict allowed redirect domains, preventing open redirects.
