AWS Patches Critical 'FlowFixation' Bug in Airflow Service to Prevent Session Hijacking

AWS Patches Critical 'FlowFixation' Bug in Airflow Service to Prevent Session Hijacking

Mar 22, 2024 Amazon Web Services / Vulnerability
Cybersecurity researchers have shared details of a now-patched security vulnerability in Amazon Web Services (AWS) Managed Workflows for Apache Airflow ( MWAA ) that could be potentially exploited by a malicious actor to hijack victims' sessions and achieve remote code execution on underlying instances. The vulnerability, now addressed by AWS, has been codenamed  FlowFixation  by Tenable. "Upon taking over the victim's account, the attacker could have performed tasks such as reading connection strings, adding configurations and triggering directed acyclic graphs (DAGS)," senior security researcher Liv Matan  said  in a technical analysis. "Under certain circumstances such actions can result in RCE on the instance that underlies the MWAA, and in lateral movement to other services." The root cause of the vulnerability, per the cybersecurity firm, is a combination of  session fixation  on the web management panel of AWS MWAA and an AWS domain misconfigura

Severe Vulnerabilities Reported in Microsoft Azure Bastion and Container Registry

Jun 14, 2023 Cloud Security / Vulnerability
Two "dangerous" security vulnerabilities have been disclosed in Microsoft Azure Bastion and Azure Container Registry that could have been exploited to carry out cross-site scripting (XSS) attacks. "The vulnerabilities allowed unauthorized access to the victim's session within the compromised Azure service iframe, which can lead to severe consequences, including unauthorized data access, unauthorized modifications, and disruption of the Azure services iframes," Orca security researcher Lidor Ben Shitrit  said  in a report shared with The Hacker News. XSS attacks  take place when threat actors inject arbitrary code into an otherwise trusted website, which then gets executed every time when unsuspecting users visit the site. The two flaws identified by Orca leverage a weakness in the postMessage iframe, which enables cross-origin communication between Window objects. This meant that the shortcoming could be abused to embed endpoints within remote servers usin
