Description

Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. The server did not sufficiently validate user-supplied image URLs, allowing arbitrary external content to be embedded as profile images, which could expose users to unintended external requests and tracking by third-party servers. Users are recommended to upgrade to version 2.0.1, which fixes the issue.

Technical Analysis

Apache Answer versions up to and including 2.0.0 contain an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434). The server does not properly validate user-supplied image URLs, enabling attackers to embed arbitrary external content as profile images. This can lead to privacy concerns by causing users' clients to make unintended external requests, potentially allowing third-party servers to track users. The vulnerability has a CVSS 3.1 base score of 6.5 (medium severity) with network attack vector, low attack complexity, no privileges or user interaction required, and impacts confidentiality and integrity. The issue is resolved in Apache Answer 2.0.1.

Potential Impact

The vulnerability allows embedding of arbitrary external content as profile images, which can cause users' clients to make unintended external requests. This may expose users to privacy risks such as tracking by third-party servers. There is no indication of direct system compromise or availability impact.

Mitigation Recommendations

Users should upgrade Apache Answer to version 2.0.1 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated in the available data.
