CVE-2025-66252
Infinite Loop Denial of Service via Failed File Deletion
Infinite Loop Denial of Service via Failed File Deletion in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 allows an attacker to perform Infinite loop when unlink() fails in status_contents.php causing DoS. Due to the fact that the unlink operation is done in a while loop; if an immutable file is specified or otherwise a file in which the process has no permissions to delete; it would repeatedly attempt to do in a loop.
