CVE-2019-15974: Cisco Managed Services Accelerator Open Redirect Vulnerability

A vulnerability in the web interface of Cisco Managed Services Accelerator (MSX) could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. A successful exploit could allow the attacker to redirect a user to a malicious web page. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.

Security readout for executives and security teams

Plain-English summary

Cisco Managed Services Accelerator has an open redirect flaw in its web interface. An attacker could manipulate a user’s HTTP request so the Cisco interface sends that user to a malicious site, supporting phishing or trust-abuse scenarios. It does not provide direct system compromise by itself.

Executive priority

Treat as a moderate phishing-enablement issue, not a direct infrastructure takeover. Prioritize if MSX is internet-facing, broadly user-accessible, or used in high-trust operational workflows.

Technical view

CVE-2019-15974 is CWE-601 caused by improper input validation of HTTP request parameters in Cisco MSX. It is remotely reachable, unauthenticated, low complexity, and requires user interaction. CVSS v3.0 is 4.7 with integrity impact only.

Likely exposure

Exposure is limited to organizations running Cisco Managed Services Accelerator where users can reach the affected web interface. The source bundle does not provide affected version ranges or CPEs.

Exploitation context

The sources describe phishing-oriented abuse through open redirect behavior. KEV status is false, and the provided sources do not state active exploitation in the wild.

Researcher notes

Key gaps are affected version specificity and named remediation details in the provided bundle. Validation should avoid weaponized testing and focus on inventory, advisory matching, exposure review, and log analysis.

Mitigation direction

  • Check Cisco’s advisory for fixed releases, workarounds, and affected-version details.
  • Inventory Cisco Managed Services Accelerator deployments and ownership.
  • Limit MSX web interface exposure to trusted administrative networks where feasible.
  • Harden phishing controls for links that appear to originate from trusted Cisco-hosted interfaces.

Validation and detection

  • Confirm whether Cisco Managed Services Accelerator is deployed in the environment.
  • Map externally and internally reachable MSX web interfaces.
  • Review the Cisco advisory against deployed versions and upgrade status.
  • Inspect access logs for unusual redirect patterns or external destination parameters.
