A race condition vulnerability has been discovered in the popular WordPress TotalPoll plugin. The vulnerability allows attackers to generate votes for their favorite streamers by exploiting a race condition in the plugin's voting logic.
The vulnerability exists in the TotalPoll plugin's voting logic. When a user votes for a poll, the plugin calls a function to update the poll's vote count. However, the function does not properly synchronize access to the vote count, which can lead to a race condition.
A race condition occurs when two or more threads of execution try to access the same data at the same time. If the data is not properly synchronized, it can be possible for one thread to overwrite the changes made by another thread.
In the case of the TotalPoll plugin, the race condition can be exploited to generate multiple votes for a poll. This can be done by creating multiple threads that all try to vote for the same poll at the same time.
The vulnerability is particularly concerning because it can be used to manipulate the results of polls. For example, a streamer could use the vulnerability to generate votes for themselves in order to win a poll.
The TotalPoll plugin has been updated to fix the vulnerability. However, users who are running an older version of the plugin are still vulnerable.
- Use a web application firewall (WAF) to block malicious traffic.
