High
Showing all detectors for the Java language with high severity.
Reflected cross site scripting
Rule to detect reflected XSS.
AWS object presence check
Manually performing an object existence check is inefficient when a built-in operation is available.
Missing timeout check on CountDownLatch.await
Missing timeout check on CountDownLatch.await can cause synchronization errors.
Unspecified default value
Unspecified defaults can cause your application to crash.
Deserialization of untrusted object
Deserialization of untrusted objects can lead to security vulnerabilities such as, inadvertently running remote code.
Preserve thread interruption status rule
Preserve Thread Interruption Status Rule.
Missing null check for cache response metadata
Accessing the cache response metadata without performing a
null check might cause a null dereference error.Insecure connection using unencrypted protocol
Connections that use insecure protocols transmit data in cleartext, which can leak sensitive information.
Use of externally-controlled input to build connection string
Use of unsanitized user input to build connection strings can allow attackers to bypass security checks and access restricted resources.
Mutually exclusive call
Calls to mutually exclusive methods were found in the code.
Improper Initialization
The code failed to initialize or incorrectly initialized internal data, leading to undefined behavior.
Unexpected re-assignment of synchronized objects
Synchronized objects should not be re-assigned in the same
synchronized block because the references to the synchronized object would be lost.XPath injection
Potentially unsanitized user input in XPath queries can allow an attacker to control the query in unwanted or insecure ways.
Input and output values become out of sync
If a method that uses an input parameter to update an output value throws an exception, then the output value is not updated.
Server-side request forgery
Insufficient sanitization of potentially untrusted URLs on the server side can allow server requests to unwanted destinations.
Missing Authorization for address id
Rule to detect lack of authorization check when using address ID.
Not recommended aws credentials classes
Find usages of not recommended classes for AWS Credentials and suggest replacing them with something else.
Path traversal
Creating file paths from untrusted input might give a malicious actor access to sensitive files.
Override of reserved variable names in a Lambda function
Overriding environment variables that are reserved by AWS Lambda might lead to unexpected behavior.
Usage of an API that is not recommended
APIs that are not recommended were found.
Insecure JSON web token (JWT) parsing
JWTs should not be parsed using the
parse method.Unchecked S3 object metadata content length
Failure to specify a content length causes the contents of the input stream to buffer locally in memory in order to calculate its length. This can result in performance problems.
Untrusted data in security decision
Security decisions should not depend on branching that can be influenced by untrusted or client-provided data.
Permissive cors configuration rule
Rule to enable detection for potential CORS vulnerabilities in services using the Coral or Spring frameworks.
XML External Entity
Objects that parse or handle XML can lead to XML External Entity (XXE) attacks when misconfigured.
LDAP injection
LDAP queries that rely on potentially untrusted inputs can allow attackers to read or modify sensitive data, run code, and perform other unwanted actions.
Log injection
Using untrusted inputs in a log statement can enable attackers to break the log's format, forge log entries, and bypass log monitors.
Sensitive information leak
Sensitive information should not be exposed through log files or stack traces.
Synchronous publication of AWS Lambda metrics
Synchronous publication of AWS Lambda metrics is inefficient.
XML External Entity Document Builder Factory
Objects that parse or handle XML in XML document can lead to XML External Entity (XXE) attacks when misconfigured.
Insecure TLS version
TLS versions older than TLS version 1.1 support weak, broken, or misconfigured cryptography.
Unrestricted upload of dangerous file type
Insufficiently restrictive file uploads can lead to inadvertently running malicious code.
Insecure SAML parser configuration
Comment parsing for OpenSAML2 might enable an attacker to bypass authentication.
Cross-site request forgery
Insecure configuration can lead to a cross-site request forgery (CRSF) vulnerability.
Case sensitive keys in S3 object user metadata
User metadata keys are case insensitive and are returned as lowercase strings, even if they were originally specified with uppercase strings.
URL redirection to untrusted site
User-controlled input that specifies a link to an external site could lead to phishing attacks and allow user credentials to be stolen.
Use of externally-controlled input to select classes or code
Use of unsanitized external input in reflection can allow attackers to bypass security checks and run malicious code.
Missing encryption of sensitive data in storage
Sensitive data is potentially persisted into storage or passed to another service without always being encrypted.
Cross-site scripting
Relying on potentially untrusted user inputs when constructing web application outputs can lead to cross-site scripting vulnerabilities.
Unauthenticated LDAP requests
Unauthenticated LDAP requests can allow untrusted access to LDAP servers.
Weak obfuscation of web request
Weak obfuscation while configuring a web request
Clear text credentials
Credentials that are stored in clear text can be intercepted by a malicious actor.
Loose file permissions
Weak file permissions can lead to privilege escalation.
OS command injection
Constructing operating system or shell commands with unsanitized user input can lead to inadvertently running malicious code.
SQL injection
Use of untrusted inputs in SQL database query can enable attackers to read, modify, or delete sensitive data in the database
Object Input Stream Insecure Deserialization
Deserialization of untrusted data without sufficiently verifying that the resulting data will be valid.
Weak pseudorandom number generation
Insufficiently random generators (or hardcoded seeds) can make pseudorandom sequences predictable.
Client-side KMS reencryption
Client-side decryption followed by reencryption is inefficient and can lead to sensitive data leaks.
