Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.10% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Johnson Controls XAAP Application and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: No default targetRemediation target: Normal maintenance

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Cleartext storage of sensitive information vulnerability in Johnson Controls XAAP Application on Android allows an attacker on a jailbroken or otherwise compromised device to Retrieve Sensitive Data. This issue affects XAAP Application: before 1.53.

What

Cleartext storage of sensitive information vulnerability in Johnson Controls XAAP Application on Android allows an attacker on a jailbroken or otherwise compromised device to Retrieve Sensitive Data. This issue affects XAAP Application: before 1.53.

Why

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

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
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Official advisory ↗
CISA · English · ICSA-26-204-02Johnson Controls XAAP Android

A cleartext storage weakness exists in the Fire Solutions Android application, which stores application data locally on the device without encryption. An attacker with physical access to the device and one able to compromise the device through a separate, unrelated flaw, could potentially read this data in plaintext. Exploitation does not require network access and is limited to the local device environment.
