Update 2023-03-21 – We’ve talked with members of the NuGet team and they had already detected and removed the malicious packages in question. Malicious packages are often spread by the open source NPM and PyPI package repositories, with few other repositories affected. Specifically – there was no public evidence of severe malicious activity in the …
The recent OpenSSH double-free vulnerability – CVE-2023-25136, created a lot of interest and confusion regarding OpenSSH’s custom security mechanisms – Sandbox and Privilege Separation. Until now, both of these security mechanisms were somewhat unnoticed and only partially documented. The double-free vulnerability raised interest for those who were affected and those controlling servers that use OpenSSH. …
Our previous research on CVE exploitability in the top DockerHub images discovered that 78% of the reported CVEs were actually not exploitable. This time, the JFrog Security Research team used JFrog Xray’s Contextual Analysis feature, automatically analyzing the applicability of reported CVEs, to scan OWASP WebGoat – a deliberately insecure application. The results identified that …
OpenSSH’s newly released version 9.2p1 contains a fix for a double-free vulnerability. Given the severe potential impact of the vulnerability on OpenSSH servers (DoS/RCE) and its high popularity in the industry, this security fix prompted the JFrog Security Research team to investigate the vulnerability. This blog post provides details on the vulnerability, who is affected, …
Wow! We made it to the last post in our Malicious Packages series. While parting is such sweet sorrow, we hope blogs one, two, and three provide insights into the havoc malicious packages cause throughout your DevOps and DevSecOps pipelines. In the prior posts: We explained what software supply chain attacks are and learned the …
The JFrog Security Research team is constantly looking for new and previously unknown vulnerabilities and security issues in popular open-source projects to help improve their security posture and defend the wider software supply chain. As part of this effort, we recently discovered and disclosed multiple vulnerabilities in popular Rust projects such as Axum, Salvo and …
Last August, the maintainers of the LastPass cloud-based password manager tool reported a security breach in their servers. The disclosure maintained that an unauthorized party gained access to the LastPass development environment through a single compromised developer account. However – while source code and technical information was stolen, no user data was compromised and no …
The JFrog Security Research team continuously monitors popular open-source software (OSS) repositories with our automated tooling, and reports any vulnerabilities or malicious packages discovered to repository maintainers and the wider community. Most PyPI malware today tries to avoid static detection using various techniques: starting from primitive variable mangling to sophisticated code flattening and steganography techniques. …
The npm CLI has a very convenient and well-known security feature – when installing an npm package, the CLI checks the package and all of its dependencies for well-known vulnerabilities – The check is triggered on package installation (when running npm install) but can also be triggered manually by running npm audit. This is an …
Research motivations Similarly to our previous research on “Secrets Detection,” during the development and testing of JFrog Xray’s new “Contextual Analysis” feature, we wanted to test our detection in a large-scale real-world use case, both for eliminating bugs and testing the real-world viability of our current solution. However, unlike the surprising results we got in our …
