CVE-2024-54853

5.4 MEDIUM

📋 TL;DR

A stored cross-site scripting (XSS) vulnerability in Skybox Change Manager allows authenticated attackers to inject malicious scripts into application fields. These scripts execute in victims' browsers when they view the compromised content. This affects users of Skybox Change Manager version 13.2.170 and earlier.

💻 Affected Systems

Products:
  • Skybox Change Manager
Versions: 13.2.170 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated user access to exploit. All deployments with vulnerable versions are affected.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware on victim systems.

🟠

Likely Case

Session hijacking, credential theft, or unauthorized actions performed within the application using victim privileges.

🟢

If Mitigated

Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access. Public proof-of-concept demonstrates basic payload injection.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 13.2.171 or later

Vendor Advisory: https://github.com/KoratSec/CVEs/blob/main/CVE-2024-54853.txt

Restart Required: Yes

Instructions:

1. Download latest version from Skybox vendor portal. 2. Backup current configuration. 3. Install update following vendor documentation. 4. Restart Skybox Change Manager services. 5. Verify functionality.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side input validation to sanitize user inputs in affected fields

Content Security Policy

all

Implement strict CSP headers to prevent script execution from untrusted sources

Content-Security-Policy: default-src 'self'; script-src 'self'

🧯 If You Can't Patch

  • Restrict user permissions to minimize attack surface - limit who can modify vulnerable fields
  • Implement web application firewall (WAF) rules to block XSS payload patterns

🔍 How to Verify

Check if Vulnerable:

Check Skybox Change Manager version in administration interface. If version is 13.2.170 or earlier, system is vulnerable.

Check Version:

Check via Skybox web interface: Administration > System Information > Version

Verify Fix Applied:

Verify version is 13.2.171 or later. Test XSS payload injection in previously vulnerable fields to confirm sanitization.

📡 Detection & Monitoring

Log Indicators:

  • Unusual field modifications by authenticated users
  • JavaScript payload patterns in application logs
  • Multiple failed XSS attempts

Network Indicators:

  • Unexpected outbound connections from user browsers after viewing application pages
  • Suspicious script tags in HTTP requests

SIEM Query:

source="skybox_logs" AND ("script" OR "javascript:" OR "onerror=" OR "onload=")
