New for Amazon CodeGuru Reviewer – Detector Library and Safety Detectors for Log-Injection Flaws

Amazon CodeGuru Reviewer is a developer instrument that detects safety vulnerabilities in your code and supplies clever suggestions to enhance code high quality. For instance, CodeGuru Reviewer launched Safety Detectors for Java and Python code to establish safety dangers from the prime ten Open Net Utility Safety Challenge (OWASP) classes and comply with safety greatest practices for AWS APIs and customary crypto libraries. At re:Invent, CodeGuru Reviewer launched a secrets and techniques detector to establish hardcoded secrets and techniques and recommend remediation steps to safe your secrets and techniques with AWS Secrets and techniques Supervisor. These capabilities enable you to discover and remediate safety points earlier than you deploy.

At the moment, I’m glad to share two new options of CodeGuru Reviewer:

• A brand new Detector Library describes intimately the detectors that CodeGuru Reviewer makes use of when in search of doable defects and consists of code samples for each Java and Python.
• New safety detectors have been launched for detecting log-injection flaws in Java and Python code, just like what occurred with the current Apache Log4j vulnerability we described on this weblog put up.

Let’s see these new options in additional element.

Utilizing the Detector Library
That will help you perceive extra clearly which detectors CodeGuru Reviewer makes use of to evaluate your code, we are actually sharing a Detector Library the place yow will discover detailed info and code samples.

These detectors enable you to construct safe and environment friendly functions on AWS. Within the Detector Library, yow will discover detailed details about CodeGuru Reviewer’s safety and code high quality detectors, together with descriptions, their severity and potential affect in your utility, and extra info that helps you mitigate dangers.

Notice that every detector seems to be for a variety of code defects. We embrace one noncompliant and compliant code instance for every detector. Nevertheless, CodeGuru makes use of machine studying and automatic reasoning to establish doable points. Because of this, every detector can discover a vary of defects along with the specific code instance proven on the detector’s description web page.

Let’s take a look at a couple of detectors. One detector is in search of insecure cross-origin useful resource sharing (CORS) insurance policies which might be too permissive and will result in loading content material from untrusted or malicious sources.

One other detector checks for improper enter validation that may allow assaults and result in undesirable habits.

Particular detectors enable you to use the AWS SDK for Java and the AWS SDK for Python (Boto3) in your functions. For instance, there are detectors that may detect hardcoded credentials, reminiscent of passwords and entry keys, or inefficient polling of AWS sources.

New Detectors for Log-Injection Flaws
Following the current Apache Log4j vulnerability, we launched in CodeGuru Reviewer new detectors that test in the event you’re logging something that isn’t sanitized and presumably executable. These detectors cowl the difficulty described in CWE-117: Improper Output Neutralization for Logs.

These detectors work with Java and Python code and, for Java, usually are not restricted to the Log4j library. They don’t work by trying on the model of the libraries you utilize, however test what you might be really logging. On this manner, they’ll shield you if related bugs occur sooner or later.

Following these detectors, user-provided inputs should be sanitized earlier than they’re logged. This avoids having an attacker be capable of use this enter to interrupt the integrity of your logs, forge log entries, or bypass log displays.

Availability and Pricing
These new options can be found right now in all AWS Areas the place Amazon CodeGuru is obtainable. For extra info, see the AWS Regional Companies Checklist.

The Detector Library is free to browse as a part of the documentation. For the brand new detectors in search of log-injection flaws, commonplace pricing applies. See the CodeGuru pricing web page for extra info.

Begin utilizing Amazon CodeGuru Reviewer right now to enhance the safety of your code.
