CVE-2015-0773
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 · uneditedCisco FireSIGHT System Software 5.3.1.3 and 6.0.0 allows remote authenticated users to delete an arbitrary user's dashboard via a modified VPN deletion request in a management session, aka Bug ID CSCut67078.
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 · moderate confidenceCisco FireSIGHT System Software versions 5.3.1.3 and 6.0.0 contains an access control bypass where authenticated users can delete arbitrary user dashboards by modifying parameters in VPN deletion requests within management sessions. This is an Insecure Direct Object Reference (IDOR) vulnerability allowing unauthorized dashboard deletion across users.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Cisco FireSIGHT System Software versionLog into the FireSIGHT management console and navigate to System > Updates > Product Updates, or run 'show version' via CLI on the management applianceAffected if The installed version is 5.3.1.1 or 6.0.0 exactly (these are the affected versions listed)
-
Verify management interface accessibilityConfirm whether the FireSIGHT management interface (HTTPS on port 443) is accessible from network segments outside the trusted admin networkAffected if The management interface is exposed to untrusted networks, allowing remote authenticated attackers to exploit the IDOR vulnerability
-
Confirm user authentication is enabled for management accessCheck that user authentication is required for accessing the FireSIGHT management console - verify in System > Users > Local User Management that local users are configured and authentication is enforcedAffected if Authentication is enabled (which is required for the vulnerability to be exploitable - the flaw allows authenticated users to access other users' dashboards)
-
Review user dashboard access logs for unauthorized deletionsExamine the FireSIGHT management logs under System > Logs > Audit for events indicating dashboard deletions, particularly those performed by users deleting dashboards they do not ownAffected if Audit logs show dashboard deletion events with mismatched user context (user A deleted user B's dashboard)
You are affected if your FireSIGHT management center runs version 5.3.1.1 or 6.0.0 AND the management interface is accessible to authenticated users who could exploit the IDOR flaw to delete arbitrary dashboards.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Cisco's security update/patch for this vulnerability. If unavailable, restrict management interface access to trusted administrators only and implement audit logging for dashboard deletion operations.
