Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs TIBCO Software Inc. TIBCO Spotfire Analyst and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.

What, why and how
The Spotfire client component of TIBCO Software Inc.'s TIBCO Spotfire Analyst, TIBCO Spotfire Analytics Platform for AWS Marketplace, TIBCO Spotfire Desktop, and TIBCO Spotfire Server contains a vulnerability that theoretically allows a low privileged attacker with network access to execute a stored Cross Site Scripting (XSS) attack on the affected system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s TIBCO Spotfire Analyst: versions 10.3.3 and below, versions 10.10.0, 10.10.1, and 10.10.2, versions 10.7.0, 10.8.0, 10.9.0, 11.0.0, and 11.1.0, TIBCO Spotfire Analytics Platform for AWS Marketplace: versions 11.1.0 and below, TIBCO Spotfire Desktop: versions 10.3.3 and below, versions 10.10.0, 10.10.1, and 10.10.2, versions 10.7.0, 10.8.0, 10.9.0, 11.0.0, and 11.1.0, and TIBCO Spotfire Server: versions 10.3.11 and below, versions 10.10.0, 10.10.1, 10.10.2, and 10.10.3, versions 10.7.0, 10.8.0, 10.8.1, 10.9.0, 11.0.0, and 11.1.0.

Why
Attacker-controlled content can reach a browser as executable script without sufficient output encoding or sanitisation.
How
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- a network path → Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Network
- Privileges required
- Low: a basic authenticated account is required
- User interaction
- Required interaction required
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-79 ↗
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:HCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.- Post-exploitation / living off the land
- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
