Researchers Detail 8 Vulnerabilities in Azure HDInsight Analytics Service

Additional information have emerged about a established of now-patched cross-web page scripting (XSS) flaws in the Microsoft Azure HDInsight open up-resource analytics support that could be weaponized by a danger actor to have out malicious pursuits.

“The discovered vulnerabilities consisted of six saved XSS and two mirrored XSS vulnerabilities, just about every of which could be exploited to carry out unauthorized steps, various from facts accessibility to session hijacking and providing malicious payloads,” Orca security researcher Lidor Ben Shitrit stated in a report shared with The Hacker News.

The issues ended up dealt with by Microsoft as element of its Patch Tuesday updates for August 2023.

The disclosure comes 3 months following equivalent shortcomings ended up noted in the Azure Bastion and Azure Container Registry that could have been exploited for unauthorized information access and modifications.

The record of flaws is as follows –

• CVE-2023-35393 (CVSS score: 4.5) – Azure Apache Hive Spoofing Vulnerability
• CVE-2023-35394 (CVSS score: 4.6) – Azure HDInsight Jupyter Notebook Spoofing Vulnerability
• CVE-2023-36877 (CVSS score: 4.5) – Azure Apache Oozie Spoofing Vulnerability
