In a critical update for enterprise IT environments, Hewlett Packard Enterprise has rolled out a security patch addressing multiple vulnerabilities in its StoreOnce backup and deduplication solution, a cornerstone for many organizations’ data protection strategies.

The flaws, totaling eight in number, include a particularly severe authentication bypass vulnerability tracked as CVE-2025-37093, which could allow attackers to gain unauthorized access and potentially execute remote code on affected systems. This development has sent ripples through the industry, as StoreOnce is widely deployed in data centers to optimize backup storage and enhance recovery speeds.

The urgency of this patch cannot be overstated. According to The Hacker News, the critical flaw poses a risk of remote code execution (RCE) and authentication bypass, meaning attackers could compromise systems without any user interaction. Such vulnerabilities are a goldmine for cybercriminals, who increasingly target backup infrastructure to disrupt recovery processes or extract sensitive data. HPE’s swift response in releasing updated software underscores the gravity of the situation, as unpatched systems could serve as entry points for broader network attacks.

A Deeper Look at the Vulnerabilities

Beyond CVE-2025-37093, the other seven flaws include risks like directory traversal attacks, server-side request forgery, and arbitrary file deletion, each capable of undermining data integrity or system stability. One such vulnerability, CVE-2025-37094, could enable attackers to delete critical files, posing a direct threat to business continuity. As detailed in HPE’s official security bulletin on their support portal, these issues affect StoreOnce software versions prior to 4.3.11, and the company strongly recommends an immediate upgrade to the patched version to mitigate risks.

The potential for chaining these vulnerabilities together amplifies their danger. A skilled attacker could exploit the authentication bypass to gain initial access, then leverage directory traversal or RCE capabilities to move laterally within a network. This scenario is particularly alarming for enterprises with large, interconnected IT environments where a single breach could cascade into a full system compromise, as noted in the HPE support documentation.

Urgent Action and Mitigation Strategies

HPE has made the patched software available through its Support Center, but the onus is on organizations to act swiftly. There are no known workarounds for these vulnerabilities, making the update to version 4.3.11 or later non-negotiable. IT teams are advised to isolate vulnerable StoreOnce systems from untrusted networks until the patch is applied and to monitor for signs of unauthorized access or unusual activity, per recommendations from The Hacker News.

Additionally, organizations should consider implementing network segmentation to limit potential lateral movement by attackers. Regular reviews of system management and security protocols are also critical to maintaining integrity in the face of evolving threats. For those needing assistance, HPE encourages reaching out to their support team for guidance on the update process.

Industry Implications and Forward-Looking Measures

The disclosure of these flaws highlights a broader trend: backup solutions, once considered secondary targets, are now prime objectives for cybercriminals. As enterprises increasingly rely on data protection platforms like StoreOnce, securing these systems becomes as crucial as safeguarding primary infrastructure.

This incident serves as a stark reminder for IT leaders to prioritize patch management and vulnerability assessments. With attackers growing more sophisticated, proactive measures—coupled with rapid response to vendor alerts—will be the linchpin of resilient cybersecurity strategies in an era of relentless digital threats.
