Technical details

A stored cross-site scripting (XSS) vulnerability exists in the Distribution Lists report module of ManageEngine Exchange Reporter Plus. The root cause is improper input validation of data used to generate reports. An authenticated attacker with low-level privileges can inject malicious JavaScript into the report database; when a victim (typically an administrator) views the affected report, the script executes in their browser context. This can lead to session hijacking or unauthorized actions performed on behalf of the victim. The issue is resolved in build 5802.
