In this third post in our series on Malicious Software Packages, we’ll focus on the aftermath of a successful attack and how the attacker executes payloads to serve their needs through various real-life scenarios. Before we start, let’s review a few highlights from the second post you might’ve missed: There are common types of infection methods …
Welcome to the second post in our series on Malicious Software Packages. This post focuses on the infection methods attackers use to spread malicious packages, and how the JFrog Security research team unveiled them. If you missed the first blog, here are some key takeaways: Third-party software packages contain vulnerabilities or malicious code delivered through …
How did we get here? On October 25th, The OpenSSL team announced that OpenSSL 3.0.7 will contain a fix for a critical severity vulnerability that affects OpenSSL 3.x. The full details about the vulnerability were held in an embargo until November 1st. Due to the rarity of an OpenSSL critical-severity issue and the overwhelming popularity …
Welcome to the first post in the malicious software packages series for the DevOps and DevSecOps community. This technical series will focus on various malicious packages and their effects on the software supply chain. We’ll dive deeper into malicious packages in each post, including Defining software supply chain attacks and learning the critical role that malicious …
The JFrog Security team recently competed in the Pwn2Own Miami 2022 hacking competition which focuses on Industrial Control Systems (ICS) security. One of our research targets for the competition was the Unified Automation C++-based OPC UA Server SDK. Other than the vulnerabilities we disclosed as part of the pwn2own competition, we managed to find and …
The JFrog Security Research team continuously monitors reported vulnerabilities in open-source software (OSS) to help our customers and the wider community be aware of potential software supply chain security threats and their impact. In doing so, we often notice important trends and key learnings worth highlighting. The following analysis of a vulnerability discovered in the …
This past March we posted an analysis of a vulnerability in the Apache HTTP Server mod_sed filter module, CVE-2022-23943, in which a Denial of Service (DoS) can be triggered due to a miscalculation of buffers’ sizes. While analyzing this Apache httpd vulnerability and its patch, we suspected that although the fix resolved the issue, it …
A few weeks ago, a new version for Fastjson was released (1.2.83) which contains a fix for a security vulnerability that allegedly allows an attacker to execute code on a remote machine. According to several publications, this vulnerability allows an attacker to bypass the “AutoTypeCheck” mechanism in Fastjson and achieve remote code execution. This Fastjson …
The JFrog Security Research team is constantly looking for new and previously unknown software vulnerabilities in popular open-source projects to help improve their security posture. As part of this effort, we recently discovered a denial of service (DoS) vulnerability in Envoy Proxy, a widely used open-source edge and service proxy server, designed for cloud-native applications …
When relying on a 3rd-party package from a non-commercial entity, there is always the risk of lack of support, especially when it comes to outdated packages and versions. If the package stops being maintained, nobody will implement a new feature we might need or fix a newly-discovered security vulnerability. Consider, for example, CVE-2019-17571. A critical …
