CVE-2024-51723
📋 TL;DR
A stored cross-site scripting vulnerability in BlackBerry AtHoc version 7.15 allows attackers to inject malicious scripts into the Management Console. When viewed by administrators or other users, these scripts execute in their browser session, potentially performing unauthorized actions. This affects organizations using the vulnerable version of BlackBerry AtHoc's Management Console.
💻 Affected Systems
- BlackBerry AtHoc
📦 What is this software?
Athoc by Blackberry
⚠️ Risk & Real-World Impact
Worst Case
An attacker could hijack administrator sessions, steal credentials, modify system configurations, deploy malware to other users, or perform unauthorized administrative actions across the AtHoc platform.
Likely Case
Attackers would typically use this to steal session cookies or credentials, perform limited unauthorized actions within the Management Console, or redirect users to malicious sites.
If Mitigated
With proper input validation, output encoding, and Content Security Policy headers, the script execution would be prevented, limiting impact to data display issues only.
🎯 Exploit Status
Requires attacker to have access to inject content into the Management Console. Exploitation is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 7.15.1 or later

Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add to web server configuration: Content-Security-Policy: default-src 'self'; script-src 'self'
Input Validation Filtering
allImplement server-side input validation to sanitize user inputs
Implement input validation in application code to filter <script> tags and JavaScript events
🧯 If You Can't Patch
- Restrict access to Management Console to trusted IP addresses only
- Implement web application firewall rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Check if AtHoc version is 7.15 by logging into Management Console and viewing version in system information
Check Version:
Check version in Management Console → System → About or via administrative interface
Verify Fix Applied:
Verify version is 7.15.1 or later and test XSS payloads in input fields to confirm they are properly sanitized
