Send the same request twice in rapid succession. If the second request succeeds when it should have failed (or vice-versa), a race condition likely exists. 5. Remediation and Defense Fixing race conditions requires ensuring

1. race.sh sets link to /tmp/dummy.
2. run.sh executes the binary. stat() sees /tmp/dummy. Check passes.
3. race.sh switches link to /root/flag.txt.
4. run.sh executes fopen(). It follows the link to /root/flag.txt (running as root) and prints the content.

Race conditions are among the most elusive bugs because they are non-deterministic; they might not trigger every time. However, for a skilled hunter, they represent a powerful way to break the logic of an application and gain unauthorized access or resources. for a specific race condition scenario? race condition hackviser
