A vulnerability was found in Voatz App on Android (Android App Software) (affected version unknown). It has been rated as problematic. Affected by this issue is an unknown functionality of the component Voter Handler. The manipulation with an unknown input leads to a information exposure vulnerability. Using CWE to declare the problem leads to CWE-203. The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not. Impacted is confidentiality. CVE summarizes:

In the Voatz application 2020-01-01 for Android, the amount of data transmitted during a single voter's vote depends on the different lengths of the metadata across the available voting choices, which makes it easier for remote attackers to discover this voter's choice by sniffing the network. For example, a small amount of sniffed data may indicate that a vote was cast for the candidate with the least metadata. An active man-in-the-middle attacker can leverage this behavior to disrupt voters' abilities to vote for a candidate opposed by the attacker.

The weakness was published 02/13/2020. This vulnerability is handled as CVE-2020-8989 since 02/13/2020. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
