## Summary

Vembu BDRSuite, a backup and disaster recovery product, is affected by a flaw that lets an attacker without logging in inject malicious scripts into its backup progress page through crafted links or requests. When a victim opens such a link, the script runs in their browser, which could allow session hijacking or manipulation of the web interface.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Vembu Technologies BDRSuite: fixed in 7.6.0

## Description

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.
