Vembu BDRSuite before 7.6.0 contains an unauthenticated cross-site scripting vulnerability in templates/progress/serverside/serverbackupprogress.sgp that allows remote attackers to inject arbitrary JavaScript by manipulating request parameters such as ClientName, BackupName, and grpName that are interpolated unsanitized into loadXMLDoc() calls and reflected in AbortBackup() POST requests to dodeleteclientbackup.sgp. Attackers can craft malicious links or requests to execute arbitrary JavaScript in a victim's browser session, enabling session hijacking or interface manipulation.
