HPE Issues Security Patch for StoreOnce Bug Allowing Remote Authentication Bypass

Hewlett Packard Enterprise (HPE) has released security updates to address as many as eight vulnerabilities in its StoreOnce data backup and deduplication solution that could result in an authentication bypass and remote code execution.

“These vulnerabilities could be remotely exploited to allow remote code execution, disclosure of information, server-side request forgery, authentication bypass, arbitrary file deletion, and directory traversal information disclosure vulnerabilities,” HPE said in an advisory.

This includes a fix for a critical security flaw tracked as CVE-2025-37093, which is rated 9.8 on the CVSS scoring system. It has been described as an authentication bypass bug affecting all versions of the software prior to 4.3.11. The vulnerability, along with the rest, was reported to the vendor on October 31, 2024.

According to the Zero Day Initiative (ZDI), which credited an anonymous researcher for discovering and reporting the shortcoming, said the problem is rooted in the implementation of the machineAccountCheck method.

“The issue results from improper implementation of an authentication algorithm,” ZDI said. “An attacker can leverage this vulnerability to bypass authentication on the system.”

Successful exploitation of CVE-2025-37093 could permit a remote attacker to bypass authentication on affected installations. What makes the vulnerability more severe is that it could be chained with the remaining flaws to achieve code execution, information disclosure, and arbitrary file deletion in the context of root –

• CVE-2025-37089 – Remote Code Execution
• CVE-2025-37090 – Server-Side Request Forgery
• CVE-2025-37091 – Remote Code Execution
• CVE-2025-37092 – Remote Code Execution
• CVE-2025-37093 – Authentication Bypass
• CVE-2025-37094 – Directory Traversal Arbitrary File Deletion
• CVE-2025-37095 – Directory Traversal Information Disclosure
• CVE-2025-37096 – Remote Code Execution

The disclosure comes as HPE also shipped patches to address multiple critical-severity flaws in HPE Telco Service Orchestrator (CVE-2025-31651, CVSS score: 9.8) and OneView (CVE-2024-38475, CVE-2024-38476, CVSS scores: 9.8) to address previously disclosed weaknesses in Apache Tomcat and Apache HTTP Server.

While there are no reports of active exploitation, it’s essential that users apply the latest updates for optimal protection.
