Weakness ID: 522

Vulnerability Mapping: ALLOWED This CWE ID could be used to map to real-world vulnerabilities in limited situations requiring careful review (with careful review of mapping notes)
Abstraction: Class Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.

Description

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

Common Consequences

This 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.

Scope	Impact	Likelihood
Access Control	Technical Impact: Gain Privileges or Assume Identity An attacker could gain access to user accounts and access sensitive data used by the user accounts.

Potential Mitigations

Phase: Architecture and Design

Use an appropriate security mechanism to protect the credentials.

Phase: Architecture and Design

Make appropriate use of cryptography to protect the credentials.

Phase: Implementation

Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).

Applicable Platforms

This 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)

Technologies

Class: ICS/OT (Undetermined Prevalence)

Demonstrative Examples

Example 1

This code changes a user's password.

(bad code)

Example Language: PHP

$user = $_GET['user'];
$pass = $_GET['pass'];
$checkpass = $_GET['checkpass'];
if ($pass == $checkpass) {

SetUserPassword($user, $pass);

}

While the code confirms that the requesting user typed the same new password twice, it does not confirm that the user requesting the password change is the same user whose password will be changed. An attacker can request a change of another user's password and gain control of the victim's account.

Example 2

The following code reads a password from a properties file and uses the password to connect to a database.

(bad code)

Example Language: Java

...
Properties prop = new Properties();
prop.load(new FileInputStream("config.properties"));
String password = prop.getProperty("password");
DriverManager.getConnection(url, usr, password);
...

This code will run successfully, but anyone who has access to config.properties can read the value of password. If a devious employee has access to this information, they can use it to break into the system.

Example 3

The following code reads a password from the registry and uses the password to create a new network credential.

(bad code)

Example Language: Java

...
String password = regKey.GetValue(passKey).toString();
NetworkCredential netCred = new NetworkCredential(username,password,domain);
...

This code will run successfully, but anyone who has access to the registry key used to store the password can read the value of password. If a devious employee has access to this information, they can use it to break into the system

Example 4

Both of these examples verify a password by comparing it to a stored compressed version.

(bad code)

Example Language: C

int VerifyAdmin(char *password) {

if (strcmp(compress(password), compressed_password)) {

printf("Incorrect Password!\n");
return(0);

}
printf("Entering Diagnostic Mode...\n");
return(1);

}

(bad code)

Example Language: Java

int VerifyAdmin(String password) {

if (passwd.Equals(compress(password), compressed_password)) {

return(0);

}
//Diagnostic Mode
return(1);

}

Because a compression algorithm is used instead of a one way hashing algorithm, an attacker can recover compressed passwords stored in the database.

Example 5

The following examples show a portion of properties and configuration files for Java and ASP.NET applications. The files include username and password information but they are stored in cleartext.

This Java example shows a properties file with a cleartext username / password pair.

(bad code)

Example Language: Java

# Java Web App ResourceBundle properties file
...
webapp.ldap.username=secretUsername
webapp.ldap.password=secretPassword
...

The following example shows a portion of a configuration file for an ASP.Net application. This configuration file includes username and password information for a connection to a database but the pair is stored in cleartext.

(bad code)

Example Language: ASP.NET

...
<connectionStrings>

</connectionStrings>
...

Username and password information should not be included in a configuration file or a properties file in cleartext as this will allow anyone who can read the file access to the resource. If possible, encrypt this information.

Example 6

In 2022, the OT:ICEFALL study examined products by 10 different Operational Technology (OT) vendors. The researchers reported 56 vulnerabilities and said that the products were "insecure by design" [REF-1283]. If exploited, these vulnerabilities often allowed adversaries to change how the products operated, ranging from denial of service to changing the code that the products executed. Since these products were often used in industries such as power, electrical, water, and others, there could even be safety implications.

Multiple vendors used cleartext transmission or storage of passwords in their OT products.

Detection Methods

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Effectiveness: High
