CVE-2023-24489, a critical Citrix ShareFile vulnerability that the company has fixed in June 2023, is being exploited by attackers.
GreyNoise has flagged on Tuesday a sudden spike in IP addresses from which exploitation attempts are coming, and the Cybersecurity and Infrastructure Agency has added the vulnerability to its Known Exploited Vulnerabilities Catalog.
Unearthed and reported by Assetnote researcher Dylan Pindur, CVE-2023-24489 affects the popular cloud-based file-sharing application Citrix ShareFile, more specifically its storage zones controller.
“You can use the ShareFile-managed cloud storage by itself or in combination with storage that you maintain, called storage zones for ShareFile Data. The storage zones that you maintain can reside in your on-premises single-tenant storage system or in supported third-party cloud storage,” Citrix explains.
Storage zones controller allows users to securely access SharePoint sites and network file shares through storage zone connectors, which enable ShareFile client users to browse, upload, or download documents.
CVE-2023-24489 has been fixed in ShareFile storage zones controller v5.11.24 and later, and customers have been urged to upgrade ever since.
