How the Exploit Works
The CVE-2025-5966 exploit takes advantage of a Stored XSS vulnerability in the “Attachments by filename keyword” report functionality of the affected software. An attacker could inject malicious script into the filename of an attachment. When a user opens a report containing this manipulated attachment, the script is executed, compromising the system or leading to data leakage.
Conceptual Example Code
This is a conceptual example of how the vulnerability might be exploited using a maliciously crafted HTTP POST request.
POST /report/attachment HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "attachment_filename": "<script>malicious code here</script>" }In this example, the ‘attachment_filename’ is used to inject a malicious script. When this filename is included in a report and viewed by a user, the script is executed, exploiting the vulnerability.
Mitigation Guidance
The recommended mitigation for CVE-2025-5966 is to apply the patch provided by Zohocorp for ManageEngine Exchange Reporter Plus. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation until the patch can be applied. These systems should be configured to detect and block suspicious script injections in filenames.
