CVE-2025-23392

5.2 MEDIUM

📋 TL;DR

This CVE describes a basic cross-site scripting (XSS) vulnerability in spacewalk-java that allows attackers to inject and execute arbitrary JavaScript code in web pages. It affects SUSE Manager Server containers and modules, potentially compromising user sessions and allowing data theft or further attacks. Systems running vulnerable versions of SUSE Manager Server 5.0 containers and 4.3 modules are affected.

💻 Affected Systems

Products:
  • SUSE Manager Server 5.0 containers
  • SUSE Manager Server Module 4.3
Versions: SUSE Manager Server 5.0 containers: before 5.0.24-150600.3.25.1; SUSE Manager Server Module 4.3: before 4.3.85-150400.3.105.3
Operating Systems: SUSE Linux Enterprise Server
Default Config Vulnerable: ⚠️ Yes
Notes: Affects web interface components of SUSE Manager where user input is not properly sanitized.

⚠️ 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).

  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 administrator credentials, hijack user sessions, perform actions as authenticated users, deface web interfaces, or use the compromised system as a pivot point for further attacks.

🟠

Likely Case

Session hijacking, credential theft, or unauthorized actions performed by authenticated users through malicious JavaScript execution.

🟢

If Mitigated

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

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

XSS vulnerabilities typically require user interaction (clicking a malicious link) but are straightforward to exploit once identified.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: SUSE Manager Server 5.0 containers: 5.0.24-150600.3.25.1 or later; SUSE Manager Server Module 4.3: 4.3.85-150400.3.105.3 or later

Vendor Advisory: https://bugzilla.suse.com/show_bug.cgi?id=CVE-2025-23392

Restart Required: Yes

Instructions:

1. Update SUSE Manager Server using 'zypper update' or SUSE Manager web interface. 2. Apply patches for spacewalk-java components. 3. Restart affected services (spacewalk services). 4. Verify the update with version checks.

🔧 Temporary Workarounds

Implement Content Security Policy

linux

Add CSP headers to restrict script execution sources and reduce XSS impact.

Add 'Content-Security-Policy' header to web server configuration with appropriate directives

Input Validation Filtering

all

Implement additional input validation at web application level to filter script tags.

Configure web application firewall rules to block script injection patterns

🧯 If You Can't Patch

  • Implement strict Content Security Policy headers to limit script execution
  • Deploy web application firewall with XSS protection rules

🔍 How to Verify

Check if Vulnerable:

Check installed version of spacewalk-java packages: 'rpm -qa | grep spacewalk-java' and compare with vulnerable versions.

Check Version:

rpm -q spacewalk-java

Verify Fix Applied:

Verify package version is at or above patched version: 'rpm -q spacewalk-java' should show 5.0.24-150600.3.25.1 or later for 5.0, or 4.3.85-150400.3.105.3 or later for 4.3.

📡 Detection & Monitoring

Log Indicators:

  • Unusual JavaScript execution in web logs
  • Suspicious input patterns containing script tags in access logs
  • Error logs showing script execution failures

Network Indicators:

  • HTTP requests containing script injection patterns
  • Unusual outbound connections from web server to external domains

SIEM Query:

web_access_logs WHERE url CONTAINS '<script' OR url CONTAINS 'javascript:' OR parameters CONTAINS malicious patterns
