Security misconfiguration is the most common issue in application security. This includes insecure default configurations, incomplete configurations, open cloud storage, misconfigured HTTP headers, verbose error messages, and unnecessary features or services enabled.
CodeAnt AI detects Security Misconfiguration vulnerabilities across 17 languages: Python, Java, JavaScript, Go, C#, Ruby, PHP, Kotlin, Swift, Scala, C++, Clojure, Elixir, Terraform, Dockerfile, JSON, YAML.

​
Detected Vulnerabilities

Severity: Medium

​
Description

The application or its components are configured in a way that introduces security vulnerabilities, such as overly permissive settings, disabled security features, or exposed management interfaces.

​
Impact

Misconfigured applications expose unnecessary attack surface. Default credentials, open ports, enabled debug modes, and excessive permissions are common entry points for attackers.

​
Remediation

Establish a hardened baseline configuration. Disable unnecessary features, ports, and services. Review all default settings. Automate configuration management. Conduct regular configuration audits.
Severity: Medium

​
Description

The application writes sensitive information such as passwords, tokens, API keys, or personal data into log files that may be accessible to unauthorized actors.

​
Impact

Sensitive data in logs can be exposed through log aggregation systems, file access, or log management tools, leading to credential theft and privacy violations.

​
Remediation

Sanitize all log output to remove sensitive data. Use structured logging with field-level controls. Implement log redaction for known sensitive patterns. Restrict access to log files and systems.
Severity: High

​
Description

The application processes XML documents without restricting recursive entity definitions, making it vulnerable to XML bomb attacks (billion laughs attack) that cause denial of service.

​
Impact

A small malicious XML document can expand to consume gigabytes of memory, causing application crashes and denial of service.

​
Remediation

Disable DTD processing in XML parsers. Set limits on entity expansion. Use safe XML parsing libraries like defusedxml. Implement resource limits on XML processing.
Severity: High

​
Description

The application configures Cross-Origin Resource Sharing (CORS) with overly permissive policies such as wildcard origins or reflecting arbitrary Origin headers.

​
Impact

Attackers from any origin can make authenticated cross-origin requests to the application, potentially reading sensitive data or performing actions on behalf of the user.

​
Remediation

Restrict CORS origins to specific, trusted domains. Never use wildcard (*) with credentials. Validate Origin headers server-side. Avoid reflecting the Origin header without validation.
Severity: Medium

​
Description

The web server or application is configured to display directory listings, revealing the structure and contents of directories to attackers.

​
Impact

Attackers can discover sensitive files, backup files, configuration files, and application structure that aid in further attacks.

​
Remediation

Disable directory listing on all web servers. Use explicit routing for all served content. Add index files to all directories. Configure web server to return 403/404 for directory requests.
