XSS attack | Breaking Cybersecurity News | The Hacker News

A new high-severity security flaw has been disclosed in the LiteSpeed Cache plugin for WordPress that could enable malicious actors to execute arbitrary JavaScript code under certain conditions. The flaw, tracked as CVE-2024-47374 (CVSS score: 7.2), has been described as a stored cross-site scripting ( XSS ) vulnerability impacting all versions of the plugin up to and including 6.5.0.2. It was addressed in version 6.5.1 on September 25, 2024, following responsible disclosure by Patchstack Alliance researcher TaiYou. "It could allow any unauthenticated user from stealing sensitive information to, in this case, privilege escalation on the WordPress site by performing a single HTTP request," Patchstack said in a report.  The flaw stems from the manner in which the plugin the "X-LSCACHE-VARY-VALUE" HTTP header value is parsed without adequate sanitization and output escaping, thereby allowing for injection of arbitrary web scripts.

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...
