A lot of reported CVEs for Docker Center images are safe


During the advancement of JFrog Xray’s Tricks Detection, we evaluated its capabilities by scanning more than 8 million artifacts in popular open-source bundle pc registries. Similarly, for JFrog Xray’s new Container Contextual Analysis feature, we once again tested our detection in a large-scale, real-world usage case, both for removing bugs and for assessing the real-world viability of our existing solution.However, unlike the unexpected results we got in our Tricks Detection research(we found much more active access tokens than we bargained for), the outcomes of our scans of Docker Center container images remained in line with what we were seeing, as security engineers, for many years now.Namely, when the metric for a susceptible system is just “package X is installed,” we expect most security informs to be incorrect positives. And this was precisely the case for the CVEs we found in container images on Docker Hub.In this post we will detail our research approach and findings and use some recommendations for developers and security experts wanting to minimize the volume of CVE false positives. Exploitable vs. ‘susceptible package is installed’ Before diving in

, let’s briefly look at some example vulnerabilities to understand cases where a CVE report could be thought about a false positive, even when a susceptible part exists.This is not an exhaustive list by any methods, but it does cover the most popular causes of CVE incorrect

positives. Library vulnerabilities JFrog Does the truth that a susceptible version of Lodash is set up warranty a vulnerable system?No. By meaning, we can not

identify whether a CVE in a library is exploitable simply by noting that the library is set up. This is since a library is notjfrog cca 01 a runnable entity; there need to be some other code in the system that utilizes the library in a vulnerable manner. In the example above, even if Lodash is set up, the system may not be susceptible. There should be some code that calls the vulnerable function, in this case template( ), from the susceptible Lodash library. In many cases, there are even additional requirements, such as that a person of the arguments passed to design template

() would be attacker-controlled. Other code-related prerequisites might consist of: Whether a mitigating function is called prior to the susceptible function. Whether particular arguments of the susceptible function are set to specific susceptible worths. Service setup JFrog Does the reality that a susceptible version of Cassandra is installed warranty a susceptible system?No. In a lot of modern service vulnerabilities (especially ones with extreme impact

)the vulnerability only

jfrog cca 02 manifests in non-default configurations of the service. This is because the default and sane configuration is

frequently checked the most, either by the designers themselves or merely by the real-world users of the service. In the example above, to achieve remote code execution (RCE), the Cassandra service should be configured with 3 non-default setup flags( among them being rather unusual ). Other configuration-related requirements may include: Whether the part is being kept up particular command-line arguments or environment variables. Whether the vulnerable component was put together with particular develop flags. Running environment JFrog Does the reality that a vulnerable version of Apache Hadoop is set up assurance a vulnerable system?No. In the example above, the vulnerability

only manifests in a Microsoft Windows environment. Therefore if the vulnerable component is set up in a Linux environment, it can not be exploited. Other environment-related prerequisites might consist of: Whether the vulnerable element is running in a specific distribution(e.g. Debian)Whether the susceptible part

is assembled for a particular architecture(e.g. 32-bit Arm). Whether a firewall software obstructs interaction to the susceptible service. Our research approach In this research study, we set out to discover what percentage of vulnerability reports really show that the vulnerability is exploitable, when thinking about two reporting strategies: Naive.

The vulnerability is reported whenever a susceptible

For instance, the most accurate kind of contextual scanner need to a minimum of: Allow for an unlimited call depth when trying to build an intra-module information flow graph in between an attacker-controlled source and the requested sink. Consider inter-module calls when building the data flow chart. These operations greatly increase the scanner’s run time.When dealing with a great amount of scanned artifacts per minute (as may be asked for from a JFrog Artifactory/Xray instance)we should accomplish a delicate balance between the precision and the speed of the contextual scanner.Even when thinking about the

talked about constraints, 78% is still a huge number of vulnerabilities that can be either de-prioritized or overlooked. Additionally, we anticipate this number to end up being greater as innovation advances and as less”relevant by default “CVEs are discovered. Source
