Security readout for executives and security teams
Plain-English summary
Certain Cloudera Manager versions created configuration files with overly broad read access when starting YARN NodeManager. A local user on an affected host could read sensitive files, such as keytabs or SSL configuration, which may expose credentials or trust material.
Executive priority
Treat as a credential-exposure risk on older Hadoop infrastructure. Prioritize systems with shared shell access, multi-tenant workloads, or sensitive Kerberos and TLS material.
Technical view
CVE-2015-2263 is a local information disclosure issue in Cloudera Manager 4.x and several 5.x branches before listed fixed releases. The issue involves global read permissions in /var/run/cloudera-scm-agent/process during YARN NodeManager startup, exposing files such as yarn.keytab or ssl-server.xml.
Likely exposure
Exposure is likely limited to Cloudera Manager deployments on the affected versions where untrusted or lower-privileged local users can access managed hosts running YARN NodeManager.
Exploitation context
The source bundle does not show active exploitation, and the CVE is not listed as KEV. The described attacker position is local user access, not remote unauthenticated access.
Researcher notes
No CVSS or CWE is provided in the bundle. The strongest evidence is the CVE description and Cloudera reference. Avoid assuming remote exploitability or public weaponization without additional sourced evidence.
Mitigation direction
- Upgrade affected 5.0.x, 5.1.x, 5.2.x, and 5.3.x deployments to the fixed versions or later.
- For 4.x deployments, check Cloudera vendor guidance for supported remediation or migration advice.
- Restrict local shell access on affected hosts to trusted administrators only.
- Rotate exposed keytabs or certificates if readable sensitive files were present.
Validation and detection
- Inventory Cloudera Manager versions across Hadoop management hosts.
- Confirm whether YARN NodeManager is managed by affected Cloudera Manager versions.
- Review configuration directory permissions for globally readable sensitive files.
- Check whether yarn.keytab or ssl-server.xml was exposed to non-admin local users.
