Extra information have emerged about a established of now-patched cross-web-site scripting (XSS) flaws in the Microsoft Azure HDInsight open-supply analytics provider that could be weaponized by a threat actor to carry out destructive routines.
“The recognized vulnerabilities consisted of 6 stored XSS and two mirrored XSS vulnerabilities, every single of which could be exploited to complete unauthorized steps, various from data accessibility to session hijacking and providing malicious payloads,” Orca security researcher Lidor Ben Shitrit said in a report shared with The Hacker News.
The issues were being resolved by Microsoft as portion of its Patch Tuesday updates for August 2023.
The disclosure comes a few months following equivalent shortcomings were being documented in the Azure Bastion and Azure Container Registry that could have been exploited for unauthorized information accessibility 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 rating: 4.5) – Azure Apache Oozie Spoofing Vulnerability
- CVE-2023-36881 (CVSS rating: 4.5) – Azure Apache Ambari Spoofing Vulnerability
- CVE-2023-38188 (CVSS score: 4.5) – Azure Apache Hadoop Spoofing Vulnerability
“An attacker would have to ship the target a malicious file that the target would have to execute,” Microsoft observed in its advisories for the bugs. “An authorized attacker with visitor privileges should mail a victim a destructive internet site and persuade them to open up it.”
XSS attacks come about when an adversary injects rogue scripts into a legit site, which subsequently get executed on victims’ web browsers when checking out the internet site. While reflected XSS targets consumers who are tricked into clicking on a fraudulent connection, Stored XSS is embedded in a web web site and affects all buyers accessing it.

The cloud security company reported that all the flaws stem from a absence of proper enter sanitization that makes it feasible to render malicious figures on loading the dashboard.
“These weaknesses collectively allow an attacker to inject and execute malicious scripts when the stored data is retrieved and displayed to people,” Ben Shitrit pointed out, urging businesses to carry out suitable input validation and output encoding to “ensure that consumer-generated info is correctly sanitized prior to remaining exhibited in web pages.”
