CWE-214: Invocation of Process Using Visible Sensitive Information

Weakness ID: 214
Vulnerability Mapping: ALLOWEDThis CWE ID may be used to map to real-world vulnerabilities
Abstraction: BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.
View customized information:
For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers. For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts. For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers. For users who wish to see all available information for the CWE/CAPEC entry. For users who want to customize what details are displayed.

+ Description
A process is invoked with sensitive command-line arguments, environment variables, or other elements that can be seen by other processes on the operating system.
+ Extended Description
Many operating systems allow a user to list information about processes that are owned by other users. Other users could see information such as command line arguments or environment variable settings. When this data contains sensitive information such as credentials, it might allow other users to launch an attack against the product or related resources.
+ Common Consequences
Section HelpThis table 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.

+ Relationships
Section HelpThis table 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.

ChildOfBaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.497Exposure of Sensitive System Information to an Unauthorized Control Sphere
PeerOfVariantVariant - a weakness that is linked to a certain type of product, typically involving a specific language or technology. More specific than a Base weakness. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource.526Cleartext Storage of Sensitive Information in an Environment Variable

Operation
+ Applicable Platforms
Section HelpThis listing shows possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.

Languages

Class: Not Language-Specific (Undetermined Prevalence)

+ Demonstrative Examples

Example 1

In the example below, the password for a keystore file is read from a system property.

(bad code)
Example Language: Java 
String keystorePass = System.getProperty("javax.net.ssl.keyStorePassword");
if (keystorePass == null) {
System.err.println("ERROR: Keystore password not specified.");
System.exit(-1);
}

...

If the property is defined on the command line when the program is invoked (using the -D... syntax), the password may be displayed in the OS process list.


+ Observed Examples
ReferenceDescription
password passed on command line
password passed on command line
username/password on command line allows local users to view via "ps" or other process listing programs
Username/password on command line allows local users to view via "ps" or other process listing programs.
PGP passphrase provided as command line argument.
Kernel race condition allows reading of environment variables of a process that is still spawning.
Code analysis product passes access tokens as a command-line parameter or through an environment variable, making them visible to other processes via the ps command.

+ Vulnerability Mapping Notes

Usage: ALLOWED

(this CWE ID could be used to map to real-world vulnerabilities)

Reason: Acceptable-Use

Rationale:

This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Comments:

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
