Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the web-based management interface of Cisco Crosswork Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. This vulnerability is due to improper input validation of a parameter in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website.

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 an open redirect vulnerability in Cisco Crosswork NSO's web-based management interface. Due to improper input validation of a parameter in HTTP requests, an attacker can craft a malicious URL that tricks the web application into redirecting users to an attacker-controlled website.

MitigationApply the Cisco patch when released; in the interim, implement URL filtering and user awareness to mitigate clicking on suspicious links. Consider WAF rules to detect and block malicious redirect parameters.

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 if Cisco NSO is installed
    Run 'ncs --version' or check for NSO installation directories (typically under /opt/ncs or /nsn), or use 'rpm -q nso' or 'dpkg -l | grep nso' on Linux systems
    Affected if Cisco Network Services Orchestrator is present on the system
  2. Determine the exact NSO version
    Execute 'ncs --version' or check the version file in the NSO installation directory, or run 'show version' if accessing via CLI console
    Affected if The installed version falls within any of these ranges: 5.4 to 5.5.10.0, 5.6 to 5.6.14.2, 5.7 to 5.7.14, 5.8 to 5.8.13.0, 6.0 to 6.0.11, 6.1 to 6.1.6, or 6.2 to 6.2.1
  3. Verify if web-based management interface is enabled
    Check NSO configuration files (ncs.conf) for 'webui' or 'http' transport settings, or attempt to access the web interface on default ports 8080 (HTTP) or 8443 (HTTPS)
    Affected if The web-based management interface is enabled and reachable
  4. Confirm network exposure of the web interface
    Review firewall rules, access lists, or network segmentation to determine if the NSO web UI ports (8080, 8443, or configured custom ports) are exposed to untrusted networks
    Affected if The management interface is accessible from networks outside the trusted administrative zone

You are affected if Cisco NSO is running a version within the ranges listed AND the web-based management interface is enabled and accessible.

Upgrade available Upgrade to 5.5.10.1 / 5.6.14.3 / 5.7.15 or later
Fixed in 5.5.10.15.6.14.35.7.15
Interim mitigation

Apply the Cisco patch when released; in the interim, implement URL filtering and user awareness to mitigate clicking on suspicious links. Consider WAF rules to detect and block malicious redirect parameters.

Recommended fix High confidence

Upgrade to 5.5.10.1 (for 5.4.x), 5.6.14.3 (for 5.6.x), 5.7.15 (for 5.7.x), or 5.8.13.1 (for 5.8.x) depending on your current branch

  1. 1. Identify the currently installed Cisco NSO version via 'show version' in the CLI or through the web interface.
  2. 2. Determine which version branch your current installation belongs to (5.4.x, 5.6.x, 5.7.x, or 5.8.x).
  3. 3. For version 5.4.x: upgrade to version 5.5.10.1 or later.
  4. 4. For version 5.6.x: upgrade to version 5.6.14.3 or later.
  5. 5. For version 5.7.x: upgrade to version 5.7.15 or later.
  6. 6. For version 5.8.x: upgrade to version 5.8.13.1 or later.
  7. 7. After upgrade, verify the NSO web interface is accessible and test that URL parameters are properly validated.
