ABB Cylon Aspect 3.08.01 File Upload MD5 Checksum Bypass –

– ABB Cylon Aspect version 3.08.01 has a vulnerability in caldavInstall.php, caldavInstallAgendav.php, and caldavUpload.php files, where the presence of an EXPERTMODE parameter activates a badassMode feature. This mode allows an unauthenticated attacker to bypass MD5 checksum validation during file uploads. By enabling badassMode and setting the skipChecksum parameter, the system skips integrity verification, allowing attackers to upload or install altered CalDAV zip files without authentication. This vulnerability permits unauthorized file modifications, potentially exposing the system to tampering or malicious uploads. – Read More  – Packet Storm
