CWE-200 (信息暴露) — Vulnerability Class 2752

2752 vulnerabilities classified as CWE-200 (信息暴露). AI Chinese analysis included.

CWE-200 represents a critical information disclosure weakness where software inadvertently reveals sensitive data to unauthorized entities. This vulnerability is typically exploited by attackers who leverage insufficient access controls, insecure direct object references, or verbose error messages to harvest credentials, personal identifiable information, or internal system details. By analyzing network traffic or manipulating application inputs, adversaries can extract this exposed data to facilitate further attacks, such as identity theft or privilege escalation. To mitigate this risk, developers must implement strict access control mechanisms, ensuring that data retrieval is validated against user permissions. Additionally, employing robust encryption for data at rest and in transit, along with sanitizing error outputs to prevent information leakage, significantly reduces the attack surface. Regular security audits and adherence to the principle of least privilege further ensure that sensitive information remains protected from unauthorized exposure.

MITRE CWE Description
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include: private, personal information, such as personal messages, financial data, health records, geographic location, or contact details system status and environment, such as the operating system and installed packages business secrets and intellectual property network status and configuration the product's own code or internal state metadata, e.g. logging of connections or message headers indirect information, such as a discrepancy between two internal operations that can be observed by an outsider Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include: the product's own users people or organizations whose information is created or used by the product, even if they are not direct product users the product's administrators, including the admins of the system(s) and/or networks on which the product operates the developer Information exposures can occur in different ways: the code explicitly inserts sensitive information into …
Common Consequences (1)
ConfidentialityRead Application Data
Mitigations (1)
Architecture and DesignCompartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separatio…
Examples (2)
The following code checks validity of the supplied username and password and notifies the user of a successful or failed login.
my $username=param('username'); my $password=param('password'); if (IsValidUsername($username) == 1) { if (IsValidPassword($username, $password) == 1) { print "Login Successful"; } else { print "Login Failed - incorrect password"; } } else { print "Login Failed - unknown username"; }

Result
This code tries to open a database connection, and prints any exceptions that occur.
try { openDbConnection(); } //print exception message that includes exception message and configuration file location catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), '\n'; echo 'Check credentials in config file at: ', $Mysql_config_location, '\n'; }
