Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a stored Cross-site Scripting (XSS) vulnerability in SUSE Manager's /rhn/audit/scap/Search.do endpoint where user-supplied input is not properly sanitized before being rendered in web pages, allowing remote attackers to inject malicious JavaScript code that executes in victim browsers.

MitigationApply the SUSE security updates for the affected products (spacewalk-java, susemanager-sls, etc.) to versions 4.2.28+ for SUSE Manager 4.2 and 4.3.39+ for SUSE Manager 4.3, which contain the fix for proper input sanitization and output encoding.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify product and version
    Check if the system is running SUSE Manager Server or Uyuni. On SUSE Manager, run: rpm -q spacewalk-java or check the version via web UI (Products -> Support -> About). On Uyuni, run: rpm -q uyuni-java or check via web UI.
    Affected if The installed version is SUSE Manager Server 4.2.x before 4.2.10, 4.3.x before 4.3.2, or Uyuni before 2022.10.
  2. Verify SCAP auditing module is accessible
    Attempt to access the /rhn/audit/scap/Search.do endpoint via the web UI, or check if the SCAP auditing module is enabled in the SUSE Manager/Uyuni web interface under Security -> SCAP.
    Affected if The SCAP auditing module is enabled and the endpoint is accessible.
  3. Check for XSS vulnerability in SCAP search
    Use the SCAP Search.do endpoint to test for XSS by entering a benign test script such as <script>alert(1)</script> in any searchable field and observe if it executes or is reflected unescaped in the response.
    Affected if The malicious script executes or appears in the page source unescaped, indicating lack of proper sanitization.
  4. Confirm version is within affected range
    Compare the exact installed version to: SUSE Manager 4.2.0 through 4.2.9, SUSE Manager 4.3.0 through 4.3.1, or Uyuni versions before 2022.10. Run: rpm -q --qf '%{VERSION}-%{RELEASE}\n' spacewalk-java (for SUSE Manager) or uyuni-java (for Uyuni).
    Affected if The installed version falls within the affected ranges and the SCAP endpoint is accessible.

A defender is affected if they run SUSE Manager Server 4.2.x (<4.2.10), 4.3.x (<4.3.2), or Uyuni (<2022.10) with the SCAP auditing module enabled and the /rhn/audit/scap/Search.do endpoint accessible.

Upgrade available Upgrade to 4.2.10 / 4.3.2 / 2022.10 or later
Fixed in 4.2.104.3.22022.10
Interim mitigation

Apply the SUSE security updates for the affected products (spacewalk-java, susemanager-sls, etc.) to versions 4.2.28+ for SUSE Manager 4.2 and 4.3.39+ for SUSE Manager 4.3, which contain the fix for proper input sanitization and output encoding.

Recommended fix High confidence

SUSE Manager Server 4.2 -> 4.2.10+ | SUSE Manager Server 4.3 -> 4.3.2+ | Uyuni -> 2022.10+

  1. Identify your currently installed SUSE Manager Server or Uyuni version using 'rpm -q susemanager' or checking the web UI version info
  2. For SUSE Manager Server 4.2.x: Upgrade to version 4.2.10 or later by running 'zypper dup' or 'zypper update' to apply latest maintenance updates
  3. For SUSE Manager Server 4.3.x: Upgrade to version 4.3.2 or later by running 'zypper dup' or 'zypper update' to apply latest maintenance updates
  4. For Uyuni: Upgrade to version 2022.10 or later by running 'zypper dup' or 'zypper update' to apply latest maintenance updates
  5. After upgrade, verify the version with 'rpm -q spacewalk-java' or check the web UI to confirm the patch was applied
  6. Test the /rhn/audit/scap/Search.do endpoint to confirm the XSS vulnerability is no longer present
Caveat Standard maintenance upgrades typically have minimal breaking changes; review SUSE Manager release notes before upgrading
