> Multiple HPE StoreOnce flaws chain to enable remote code execution; no wild exploitation reported yet.

HPE has disclosed multiple vulnerabilities affecting StoreOnce Software versions prior to 4.3.11 that, when chained together, enable remote code execution and full system compromise. The affected software is a data protection platform using deduplication for backup storage. The vulnerability set includes four RCE flaws (CVE-2025-37089, CVE-2025-37091, CVE-2025-37092, CVE-2025-37096), server-side request forgery (CVE-2025-37090), authentication bypass (CVE-2025-37093), directory traversal with arbitrary file deletion (CVE-2025-37094), and directory traversal information disclosure (CVE-2025-37095). All are reachable as exploit-public-facing-application attacks requiring no prior authentication.

No active exploitation has been observed in the wild as of the advisory date. Organizations running StoreOnce for backup and recovery operations should prioritize patching to version 4.3.11 or later immediately, as the chaining of these flaws presents a complete compromise vector. Defenders should apply updates after testing, implement network segmentation to isolate backup appliances, enforce least-privilege account practices, and conduct vulnerability scans to identify affected instances.
