CWE-220: Sensitive Data Under FTP Root

Weakness ID: 220
Abstraction: Variant
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The application stores sensitive data under the FTP document root with insufficient access control, which might make it accessible to untrusted parties.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

+ Background Details
Various Unix FTP servers require a password file that is under the FTP root, due to use of chroot.
+ Modes Of Introduction

The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the software life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

Class: Language-Independent (Undetermined Prevalence)

+ Common Consequences

The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

ScopeImpactLikelihood
Confidentiality

Technical Impact: Read Application Data

+ Potential Mitigations

Phases: Implementation; System Configuration

Avoid storing information under the FTP root directory.

Phase: System Configuration

Access control permissions should be set to prevent reading/writing of sensitive files inside/outside of the FTP directory.
