Amazon CodeGuru Reviewer is a developer device that detects safety vulnerabilities in your code and offers clever suggestions to enhance code high quality. For instance, CodeGuru Reviewer launched Safety Detectors for Java and Python code to determine safety dangers from the high ten Open Internet Software Safety Venture (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 determine hardcoded secrets and techniques and counsel remediation steps to safe your secrets and techniques with AWS Secrets and techniques Supervisor. These capabilities provide help to discover and remediate safety points earlier than you deploy.
Right this moment, I’m pleased to share two new options of CodeGuru Reviewer:
- A brand new Detector Library describes intimately the detectors that CodeGuru Reviewer makes use of when on the lookout for potential defects and contains code samples for each Java and Python.
- New safety detectors have been launched for detecting log-injection flaws in Java and Python code, much like what occurred with the current Apache Log4j vulnerability we described on this weblog publish.
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 you will discover detailed data and code samples.
These detectors provide help to construct safe and environment friendly purposes on AWS. Within the Detector Library, you will discover detailed details about CodeGuru Reviewer’s safety and code high quality detectors, together with descriptions, their severity and potential influence in your software, and extra data that helps you mitigate dangers.
Be aware that every detector seems to be for a variety of code defects. We embody one noncompliant and compliant code instance for every detector. Nevertheless, CodeGuru makes use of machine studying and automatic reasoning to determine potential 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 on the lookout for insecure cross-origin useful resource sharing (CORS) insurance policies which can 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 conduct.
Particular detectors provide help to use the AWS SDK for Java and the AWS SDK for Python (Boto3) in your purposes. For instance, there are detectors that may detect hardcoded credentials, resembling 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 verify in case you’re logging something that isn’t sanitized and probably executable. These detectors cowl the problem described in CWE-117: Improper Output Neutralization for Logs.
These detectors work with Java and Python code and, for Java, are usually not restricted to the Log4j library. They don’t work by wanting on the model of the libraries you utilize, however verify what you might be really logging. On this manner, they will defend 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 at present in all AWS Areas the place Amazon CodeGuru is obtainable. For extra data, see the AWS Regional Companies Record.
The Detector Library is free to browse as a part of the documentation. For the brand new detectors on the lookout for log-injection flaws, customary pricing applies. See the CodeGuru pricing web page for extra data.
Begin utilizing Amazon CodeGuru Reviewer at present to enhance the safety of your code.
