CVE-2023-27515
📋 TL;DR
This cross-site scripting (XSS) vulnerability in Intel DSA software allows unauthenticated attackers to inject malicious scripts via network access. If exploited, it could enable privilege escalation by tricking authenticated users into executing attacker-controlled code. Organizations using Intel DSA software versions before 23.1.9 are affected.
💻 Affected Systems
- Intel(R) Driver & Support Assistant (DSA)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain administrative privileges on the Intel DSA system, potentially compromising the entire management infrastructure and accessing sensitive system information.
Likely Case
Attackers could steal session cookies or credentials from authenticated users, leading to unauthorized access to the DSA management interface.
If Mitigated
With proper network segmentation and access controls, impact is limited to the DSA management interface only.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity, but successful privilege escalation requires additional steps.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 23.1.9 or later
Vendor Advisory: http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00878.html
Restart Required: Yes
Instructions:
1. Download Intel DSA version 23.1.9 or later from Intel's official website. 2. Run the installer to update the software. 3. Restart the system to complete the installation.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Intel DSA management interface to trusted networks only
Web Application Firewall
allDeploy WAF with XSS protection rules to filter malicious input
🧯 If You Can't Patch
- Disable or restrict access to Intel DSA web interface
- Implement strict input validation and output encoding at the application layer
🔍 How to Verify
Check if Vulnerable:
Check Intel DSA version in the application interface or via 'Intel DSA' in Windows Programs and FeaturesCheck Version:
On Windows: Check 'Programs and Features' or run the Intel DSA application and view version in About sectionVerify Fix Applied:
Verify installed version is 23.1.9 or later and test XSS payloads are properly sanitized📡 Detection & Monitoring
Log Indicators:
