CVE-2018-1217 — Dell Emc Avamar security vulnerability

Critical CVSS 9.8

Avamar Installation Manager in Dell EMC Avamar Server 7.3.1, 7.4.1, and 7.5.0, and Dell EMC Integrated Data Protection Appliance 2.0 and 2.1, is affected by a missing access control check vulnerability which could potentially allow a remote unauthenticated attacker to read or change the Local Download Service (LDLS) credentials. The LDLS credentials are used to connect to Dell EMC Online Support. If the LDLS configuration was changed to an invalid configuration, then Avamar Installation Manager may not be able to connect to Dell EMC Online Support web site successfully. The remote unauthenticated attacker can also read and use the credentials to login to Dell EMC Online Support, impersonating the AVI service actions using those credentials.

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.
