CVE-2025-32753 Overview
CVE-2025-32753 is a SQL injection vulnerability in Dell PowerScale OneFS versions 9.5.0.0 through 9.10.0.1. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. A local, low-privileged attacker can exploit this weakness to trigger denial of service, disclose sensitive information, or tamper with stored data. Dell disclosed the issue in security advisory DSA-2025-208 and released fixed OneFS builds addressing the flaw.
Critical Impact
Successful exploitation compromises confidentiality, integrity, and availability of the PowerScale OneFS storage cluster, potentially exposing or altering data across managed file systems.
Affected Products
- Dell PowerScale OneFS 9.5.0.0 through 9.10.0.1
- Dell PowerScale clusters running vulnerable OneFS builds
- Dell Isilon storage nodes managed by affected OneFS versions

Technical Details for CVE-2025-32753
Vulnerability Analysis
The vulnerability resides in OneFS components that construct SQL statements using unsanitized input. Attacker-controlled data is concatenated directly into database queries without parameterization or proper escaping. This allows an authenticated local user to break out of the intended query context and inject arbitrary SQL syntax.
Because OneFS is the operating system underlying Dell PowerScale scale-out network-attached storage clusters, backend database queries frequently drive administrative and cluster-state operations. Injected SQL can therefore influence storage management logic, data catalogs, or configuration records processed by the platform.
Root Cause
The root cause is improper neutralization of special elements passed into SQL commands, classified under [CWE-89]. The affected code path fails to enforce input validation or use prepared statements when handling attacker-supplied values, allowing metacharacters such as single quotes, semicolons, and comment markers to alter query structure.
Attack Vector
Exploitation requires local access to the OneFS system with low privileges and no user interaction. An attacker leverages an authenticated shell or management interface path that ultimately feeds input into vulnerable SQL statements. Once injection succeeds, the attacker can exfiltrate query results, modify records, or cause the database engine to fail, producing denial-of-service conditions on the cluster.
No public proof-of-concept exploit has been published for CVE-2025-32753, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Refer to the Dell Security Update DSA-2025-208 for vendor-specific technical details.
Detection Methods for CVE-2025-32753
Indicators of Compromise
- Unexpected SQL syntax, metacharacters, or comment sequences (--, ;, ' OR '1'='1) appearing in OneFS command or API audit logs
- Anomalous database error messages surfaced by OneFS services following administrative input
- Unexplained modifications to OneFS configuration or catalog entries by low-privileged accounts
Detection Strategies
- Audit OneFS command history and administrative API calls for input containing SQL metacharacters submitted by non-administrative users
- Correlate local authentication events with database service errors or restarts on cluster nodes
- Baseline expected query patterns and alert on deviations that suggest injected clauses or unusual result sizes
Monitoring Recommendations
- Forward OneFS audit logs, isi command telemetry, and node syslog to a centralized SIEM for retention and analysis
- Enable alerting on repeated failed queries, sudden schema access changes, or database process crashes
- Monitor privilege usage on OneFS local accounts and flag accounts executing unusual administrative workflows
How to Mitigate CVE-2025-32753
Immediate Actions Required
- Inventory all PowerScale OneFS clusters and identify nodes running versions between 9.5.0.0 and 9.10.0.1
- Apply the fixed OneFS release referenced in Dell advisory DSA-2025-208 as soon as change windows permit
- Restrict local and administrative access on OneFS clusters to the minimum set of trusted operators
- Rotate credentials for any local OneFS accounts that may have been exposed prior to patching
Patch Information
Dell has released updated OneFS builds that remediate CVE-2025-32753. Refer to Dell Security Update DSA-2025-208 for the specific fixed versions and upgrade procedures for each supported OneFS release train.
Workarounds
- Limit shell and management-plane access to the OneFS cluster using network segmentation and jump hosts
- Enforce role-based access control so that only vetted administrators hold accounts on OneFS nodes
- Enable and review OneFS auditing to detect suspicious local activity until patches are applied
# Configuration example: verify OneFS version and restrict administrative access
isi version
isi auth roles list
isi auth roles modify SecurityAdmin --remove-user <untrusted_user>
isi audit settings modify --config-auditing-enabled=true --protocol-auditing-enabled=true
