Security readout for executives and security teams
Plain-English summary
Cisco Firepower Management Center had cross-site scripting flaws in its RSS dashboard. A remote attacker would need to trick a management-interface user into clicking a crafted link. Successful exploitation could run script in that user’s browser session or read sensitive browser-based information.
Executive priority
Treat as a moderate-priority administrative-console risk. It is not described as actively exploited, but compromise of a security management console browser session can affect sensitive operations and should be addressed in normal patch governance.
Technical view
CVE-2019-1931 covers multiple CWE-79 issues in the FMC web management interface. Cisco attributes them to insufficient validation of user-supplied input. CVSS 3.0 is 6.1, network exploitable, low complexity, no privileges required, with required user interaction and changed scope.
Likely exposure
Exposure is limited to organizations running affected Cisco Firepower Management Center instances, especially where administrators use the RSS dashboard in the web interface. The provided sources do not identify specific affected or fixed versions.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires persuading an FMC web-interface user to open a crafted link, so phishing or targeted administrator lures are the likely context.
Researcher notes
Do not assume unauthenticated direct takeover. The attacker is unauthenticated, but exploitation depends on user interaction and browser execution in an FMC user’s context. Public source detail is limited; use Cisco’s advisory for version and remediation specifics.
Mitigation direction
- Review Cisco’s advisory for affected and fixed FMC releases.
- Apply Cisco-recommended software updates or guidance where applicable.
- Restrict FMC management access to trusted administrative networks.
- Warn FMC administrators about untrusted links targeting the management interface.
Validation and detection
- Inventory Cisco Firepower Management Center deployments.
- Confirm FMC software versions against Cisco’s advisory.
- Check whether the RSS dashboard is accessible to administrative users.
- Review access controls for the FMC web management interface.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
