CVE intelligence and bounded remediation

CVE-2017-2611 — Jenkins before versions 2.44, 2.32.2 is vulnerable to an insufficient permission check for periodic processes (SECURITY-389)

Medium CVSS 4.3

Jenkins before versions 2.44, 2.32.2 is vulnerable to an insufficient permission check for periodic processes (SECURITY-389). The URLs /workspaceCleanup and /fingerprintCleanup did not perform permission checks, allowing users with read access to Jenkins to trigger these background processes (that are otherwise performed daily), possibly causing additional load on Jenkins master and agents.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
