The routine to check the log and report file permissions was not working as intended and could be bypassed locally.

After that, the file can be removed, recreated, and used for additional attacks.

CWE-367 Time-of-check Time-of-use (TOCTOU) Race Condition

The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
