Cybersecurity researchers have shared particulars of a now-patched security vulnerability in Amazon Web Companies (AWS) Managed Workflows for Apache Airflow (MWAA) that could be most likely exploited by a malicious actor to hijack victims’ periods and accomplish distant code execution on fundamental occasions.
The vulnerability, now tackled by AWS, has been codenamed FlowFixation by Tenable.
“On getting around the victim’s account, the attacker could have performed jobs such as examining link strings, adding configurations and triggering directed acyclic graphs (DAGS),” senior security researcher Liv Matan claimed in a complex examination.

“Less than sure conditions these types of steps can result in RCE on the occasion that underlies the MWAA, and in lateral movement to other services.”
The root induce of the vulnerability, for each the cybersecurity business, is a blend of session fixation on the web management panel of AWS MWAA and an AWS area misconfiguration that success in a cross-web-site scripting (XSS) attack.
Session fixation is a web attack approach that happens when a consumer is authenticated to a service devoid of invalidating any current session identifiers. This permits the adversary to pressure (aka fixate) a acknowledged session identifier on a person so that, when the consumer authenticates, the attacker has obtain to the authenticated session.
By abusing the shortcoming, a risk actor could have forced victims to use and authenticate the attacker’s recognized session and finally acquire more than the victim’s web management panel.
“FlowFixation highlights a broader issue with the current point out of cloud providers’ area architecture and management as it relates to the Community Suffix Checklist (PSL) and shared-dad or mum domains: identical-web page attacks,” Matan said, adding the misconfiguration also impacts Microsoft Azure and Google Cloud.
Tenable also pointed out that the shared architecture – exactly where many consumers have the similar mum or dad area – could be a goldmine for attackers wanting to exploit vulnerabilities like similar-web page attacks, cross-origin issues, and cookie tossing, proficiently major to unauthorized obtain, knowledge leaks, and code execution.
The shortcoming has been dealt with by the two AWS and Azure incorporating the misconfigured domains to PSL, so causing web browsers to understand the added domains as a community suffix. Google Cloud, on the other hand, has described the issue as not “critical enough” to benefit a correct.
“In the circumstance of exact same-web page attacks, the security affect of the described area architecture is significant, with heightened risk of these types of attacks in cloud environments,” Matan stated.
“Amongst these, cookie-tossing attacks and identical-site attribute cookie safety bypass are significantly regarding as each can circumvent CSRF safety. Cookie-tossing attacks can also abuse session-fixation issues.”
