CWE-420

Unprotected Alternate Channel

Base
Draft

Description

The product protects a primary channel, but it does not use the same level of protection for an alternate channel.

Common Consequences

Scope

Access Control

Impact

Gain Privileges or Assume Identity, Bypass Protection Mechanism

Potential Mitigations

Architecture and Design

Identify all alternate channels and use the same protection mechanisms that are used for the primary channels.

CVE-2020-8004

When the internal flash is protected by blocking access on the Data Bus (DBUS), it can still be indirectly accessed through the Instruction Bus (IBUS).

CVE-2002-0567

DB server assumes that local clients have performed authentication, allowing attacker to directly connect to a process to load libraries and execute commands; a socket interface also exists (another alternate channel), so attack can be remote.

CVE-2002-1578

Product does not restrict access to underlying database, so attacker can bypass restrictions by directly querying the database.

CVE-2003-1035

User can avoid lockouts by using an API instead of the GUI to conduct brute force password guessing.

CVE-2002-1863

FTP service can not be disabled even when other access controls would require it.

CVE-2002-0066

Windows named pipe created without authentication/access control, allowing configuration modification.

CVE-2004-1461

Router management interface spawns a separate TCP connection after authentication, allowing hijacking by attacker coming from the same IP address.
