Security readout for executives and security teams
Plain-English summary
CVE-2019-11276 is a token exposure issue in Pivotal Apps Manager within older Pivotal Application Service releases. Apps Manager sent token-bearing requests over unsecured HTTP, allowing an adjacent unauthenticated network user to read limited app access information and potentially change logging levels.
Executive priority
Treat this as a moderate platform hygiene issue. It is not documented as actively exploited, but affected PAS environments should be patched because token exposure can reveal access information and weaken logging reliability.
Technical view
Affected PAS versions are 2.3.x before 2.3.16, 2.4.x before 2.4.12, 2.5.x before 2.5.8, and 2.6.x before 2.6.3. The flaw involves Apps Manager requests to /cloudapplication via Spring Actuator followed by unsecured HTTP requests exposing an unencrypted token.
Likely exposure
Exposure is limited to organizations running the affected PAS release lines with Apps Manager. The attacker must be adjacent on the network, not remote over the internet by default, but shared or weakly segmented platform networks increase concern.
Exploitation context
The source bundle does not show KEV listing or confirmed active exploitation. The CVSS vector indicates adjacent-network access, low complexity, no privileges, and no user interaction. Impact is limited confidentiality and integrity, with no stated availability impact.
Researcher notes
Evidence supports CWE-319 cleartext transmission. The cited data names affected PAS lines and fixed thresholds, but does not provide exploit examples, broader product scope, or standalone mitigations beyond vendor-directed remediation.
Mitigation direction
- Upgrade affected PAS deployments to the fixed patch level or later supported release.
- Use the Pivotal advisory to confirm the correct upgrade path for each PAS line.
- Prioritize environments with shared, tenant-adjacent, or weakly segmented platform networks.
- Restrict adjacent network visibility to Apps Manager traffic until upgrades are complete.
Validation and detection
- Inventory PAS versions and identify deployments in the affected 2.3, 2.4, 2.5, and 2.6 lines.
- Confirm each deployment is at or above 2.3.16, 2.4.12, 2.5.8, or 2.6.3.
- Verify Apps Manager is present and in use on affected deployments.
- Review whether adjacent unauthenticated users could observe relevant internal HTTP traffic.
- Check for unexpected logging level changes around Apps Manager or application administration activity.
