Evidence used

  • No CISA KEV confirmation is currently recorded.

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

  1. Confirm that the asset runs Red Hat Product Security automation-controller-venv-tower-0:4.6.33-1.el8ap.aarch64 as a component of Red Hat Ansible Automation Platform 2.5 for RHEL 8 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: Within 30 daysRemediation target: Within 180 days

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.

Summary
A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The AWX_TASK_ENV setting accepts arbitrary environment variable keys with no restriction, and its values are applied directly to the running automation controller web and task processes rather than only to sandboxed execution environments. A user with the system administrator role can set variables such as REQUESTS_CA_BUNDLE, HTTPS_PROXY, SSLKEYLOGFILE, OPENSSL_CONF, or LD_PRELOAD that reconfigure the control-plane process TLS trust store, key-logging, OpenSSL engine, or dynamic linker. This enables silent interception of the outbound TLS the control plane uses to fetch external secret-store credentials and Red Hat subscription and Insights secrets, arbitrary file write of TLS session keys, and potential native code execution in the control-plane process, escalating an application administrator to compromise of the control plane and all tenant secrets.

A user with the system administrator role can set variables such as REQUESTS_CA_BUNDLE, HTTPS_PROXY, SSLKEYLOGFILE, OPENSSL_CONF, or LD_PRELOAD that reconfigure the control-plane process TLS trust store, key-logging, OpenSSL engine, or dynamic linker.

Why

One or more system settings or configuration elements can be externally controlled by a user.

How

An attacker operating through a network path may attempt exploitation with elevated 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
?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.

Likely attack path

CWE-15: External Control of System or Configuration Setting. One or more system settings or configuration elements can be externally controlled by a user.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
