CWE-527: Exposure of CVS Repository to an Unauthorized Control Sphere

Weakness ID: 527
Abstraction: Variant
Structure: Simple
Status: Incomplete
Presentation Filter:
+ Description
The product stores a CVS repository in a directory or other container that is accessible to actors outside of the intended control sphere.
+ Extended Description
Information contained within a CVS subdirectory on a web server or other server could be recovered by an attacker and used for malicious purposes. This information may include usernames, filenames, path root, and IP addresses.
+ 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.

OperationOMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.
+ 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.
