CVE-2025-13855 Overview
IBM Storage Protect Server 8.2.0 and IBM Storage Protect Plus Server contain a SQL injection vulnerability that allows remote attackers to execute specially crafted SQL statements against the application. This critical flaw enables unauthorized database manipulation, potentially allowing attackers to view, add, modify, or delete sensitive information stored in the back-end database.
Critical Impact
Remote attackers with low-privilege access can fully compromise the database backend, affecting confidentiality, integrity, and availability of enterprise backup infrastructure data.

Technical Details for CVE-2025-13855
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) exists within the IBM Storage Protect Plus Server component of IBM Storage Protect Server 8.2.0. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL statements through network-accessible interfaces.
The vulnerability requires low-privilege authentication to exploit, meaning an attacker needs valid credentials or session access before launching the attack. Once authenticated, the attacker can craft SQL statements that bypass intended query logic, gaining direct access to database operations that should be restricted.
Successful exploitation can result in complete database compromise, including extraction of sensitive backup metadata, modification of backup configurations, deletion of critical records, and potential lateral movement within the enterprise environment.
Root Cause
The root cause is improper input validation and sanitization in SQL query construction within the IBM Storage Protect Plus Server component. User-supplied input is incorporated directly into SQL queries without adequate parameterization or escaping, allowing SQL metacharacters to alter query semantics.
This vulnerability represents a classic SQL injection pattern where dynamic query construction fails to properly separate user data from SQL command syntax. The affected component likely uses string concatenation or inadequate prepared statement implementation when building database queries.
Attack Vector
The attack is network-based, requiring no user interaction for exploitation. An attacker with low-privilege access to the IBM Storage Protect Plus Server can send HTTP requests containing specially crafted SQL payloads to vulnerable endpoints.
The attack flow typically involves:
- Obtaining valid low-privilege credentials or session token
- Identifying vulnerable input parameters in the application interface
- Injecting SQL statements through these parameters
- Extracting, modifying, or deleting database contents based on the attacker's objectives
Since no public exploit code is currently available, specific injection points have not been publicly disclosed. Organizations should consult the IBM Support Page for detailed technical guidance.
Detection Methods for CVE-2025-13855
Indicators of Compromise
- Unusual database queries containing SQL metacharacters such as single quotes, semicolons, or UNION statements in application logs
- Unexpected database errors or verbose error messages returned to web interfaces
- Anomalous data access patterns or bulk data extraction from backup metadata tables
- Authentication logs showing low-privilege accounts performing administrative database operations
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests to IBM Storage Protect Plus Server
- Enable detailed database audit logging to capture and alert on suspicious query patterns
- Implement network intrusion detection signatures for SQL injection attack payloads targeting storage management systems
- Monitor application logs for database exception errors that may indicate injection attempts
Monitoring Recommendations
- Configure SIEM correlation rules to detect multiple failed SQL injection attempts followed by successful database access
- Establish baseline behavior for database queries and alert on deviations indicating injection attacks
- Monitor outbound data transfer from database servers for potential data exfiltration following successful exploitation
How to Mitigate CVE-2025-13855
Immediate Actions Required
- Apply the security patch from IBM immediately as referenced in the IBM Support Page
- Restrict network access to IBM Storage Protect Plus Server interfaces to trusted IP ranges only
- Review and audit user accounts with access to the affected server, removing unnecessary privileges
- Enable enhanced logging on database servers to capture potential exploitation attempts
Patch Information
IBM has released security updates to address this vulnerability. Organizations should consult the official IBM Support Page for specific patch versions and installation instructions.
The patch addresses the SQL injection vulnerability by implementing proper input validation and parameterized queries in the affected components. All installations of IBM Storage Protect Server 8.2.0 should be updated to the latest available version.
Workarounds
- Implement network segmentation to isolate IBM Storage Protect Plus Server from untrusted network segments
- Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the affected server
- Restrict database user permissions used by the application to minimum required privileges
- Enable multi-factor authentication for all user accounts accessing the storage management interface
# Example: Network access restriction using firewall rules
# Restrict access to IBM Storage Protect Plus Server management ports
# Allow only trusted management networks (adjust IP ranges as needed)
