## Affected

- dgtlmoon changedetection.io: 0.60.0, 0.60.1, 0.60.2, 0.60.3, 0.60.4, 0.60.5, 0.60.6, 0.60.7

## Description

A flaw has been found in dgtlmoon changedetection.io up to 0.60.7. The affected element is the function check_password of the file changedetectionio/flask_app.py of the component Hash Comparison. This manipulation of the argument Password causes observable timing discrepancy. The attack is possible to be carried out remotely. A high degree of complexity is needed for the attack. The exploitability is described as difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
