Security readout for executives and security teams
Plain-English summary
CVE-2019-19342 is an information disclosure flaw in Red Hat Ansible Tower. In affected 3.5.x and 3.6.x releases, a /websocket request involving a password containing '#' can trigger an error that exposes part of the password in plaintext.
Executive priority
Treat as a moderate-priority remediation for affected Tower deployments. The issue can leak password fragments without authentication, but available sources show low confidentiality impact and no KEV-confirmed active exploitation.
Technical view
Affected Ansible Tower versions 3.6.x before 3.6.2 and 3.5.x before 3.5.4 mishandle RabbitMQ password parsing during /websocket requests. The failure returns HTTP 500 and partially discloses the password, matching CWE-209 information exposure through error output.
Likely exposure
Exposure is limited to organizations running affected Ansible Tower 3.5.x or 3.6.x versions with the web or /websocket interface reachable. The source bundle does not provide CPEs, deployment frequency, or evidence for other Red Hat products.
Exploitation context
The CVSS vector is network-accessible, low complexity, no privileges, and no user interaction, with low confidentiality impact. The bundle says KEV is false and provides no cited evidence of active exploitation or public exploit tooling.
Researcher notes
Evidence is narrow: the bundle identifies affected version ranges, the /websocket trigger condition, RabbitMQ parsing failure, HTTP 500 behavior, and partial plaintext disclosure. It does not include a full advisory, exploit details, or environmental prerequisites beyond affected Tower versions.
Mitigation direction
- Upgrade Ansible Tower 3.5.x to 3.5.4 or later.
- Upgrade Ansible Tower 3.6.x to 3.6.2 or later.
- Review Red Hat guidance for supported remediation in your deployment branch.
- Restrict untrusted network access to the Tower web and /websocket endpoints.
- Rotate credentials if logs or errors indicate possible password exposure.
Validation and detection
- Inventory all Ansible Tower instances and record exact versions.
- Confirm no instance runs 3.5.x before 3.5.4 or 3.6.x before 3.6.2.
- Review application and proxy logs for unexpected /websocket HTTP 500 errors.
- Check whether affected endpoints are reachable from untrusted networks.
- Document credential rotation decisions for accounts that may have been exposed.
