CVE-2025-12812: Delinea Cloud Suite SQL Injection Flaw

CVE-2025-12812 Overview

CVE-2025-12812 is a SQL Injection vulnerability (CWE-89) affecting Delinea Inc. Cloud Suite and Privileged Access Service. This improper neutralization of special elements used in SQL commands allows authenticated attackers to manipulate database queries through maliciously crafted input. SQL Injection vulnerabilities in privileged access management (PAM) solutions are particularly concerning as they protect critical enterprise credentials and access controls.

Critical Impact

Authenticated attackers can exploit this SQL Injection flaw to potentially access, modify, or exfiltrate sensitive data from the Delinea Cloud Suite and Privileged Access Service databases, compromising privileged credential management systems.

Affected Products

• Delinea Cloud Suite (versions prior to 25.1)
• Delinea Privileged Access Service

Technical Details for CVE-2025-12812

Vulnerability Analysis

This SQL Injection vulnerability exists due to improper neutralization of special elements within SQL commands in Delinea's Cloud Suite and Privileged Access Service. The flaw enables authenticated users with network access to inject malicious SQL statements into application queries. When user-supplied input is incorporated into SQL queries without proper sanitization or parameterization, attackers can manipulate the query logic to perform unauthorized database operations.

The vulnerability requires low privileges and no user interaction to exploit, making it accessible to any authenticated user within the environment. While the attack complexity is low, the impact is limited to confidentiality and integrity without affecting availability, suggesting the vulnerability allows data access and modification but does not enable denial of service conditions.

Root Cause

The root cause of CVE-2025-12812 is the failure to properly neutralize or parameterize user-controlled input before incorporating it into SQL queries. This classic injection flaw occurs when applications construct SQL statements by concatenating user input directly into query strings rather than using prepared statements or parameterized queries. In the context of a privileged access management platform, this oversight represents a significant security gap in input validation controls.

Attack Vector

The attack vector is network-based, requiring an authenticated attacker to submit specially crafted input containing SQL metacharacters and commands to vulnerable application endpoints. The attacker can inject SQL syntax that modifies the intended query structure, potentially allowing them to:

• Extract sensitive data from database tables
• Modify or delete existing records
• Bypass application-level access controls
• Enumerate database schema and structure

The vulnerability mechanism involves injecting SQL fragments through application input fields that are directly concatenated into database queries. For example, an attacker might submit input containing single quotes, UNION statements, or conditional logic to alter query behavior. Technical implementation details are available in the Delinea Trust Center advisory.

Detection Methods for CVE-2025-12812

Indicators of Compromise

• Unusual database query patterns containing SQL metacharacters (', --, ;, UNION, SELECT)
• Application logs showing malformed or unexpected SQL error messages
• Anomalous data access patterns from authenticated user accounts
• Database audit logs indicating unauthorized table access or data exfiltration

Detection Strategies

• Enable detailed application and database logging to capture query parameters and execution patterns
• Deploy Web Application Firewall (WAF) rules to detect SQL Injection attempt signatures
• Monitor for authentication anomalies followed by unusual database activity
• Implement database activity monitoring (DAM) to track query patterns and alert on injection signatures

Monitoring Recommendations

• Configure alerting on SQL error messages that may indicate injection attempts
• Monitor Delinea Cloud Suite audit logs for suspicious user activity patterns
• Establish baseline database query patterns and alert on deviations
• Enable SentinelOne Singularity™ platform endpoint monitoring for suspicious process behavior associated with exploitation attempts

How to Mitigate CVE-2025-12812

Immediate Actions Required

• Upgrade Delinea Cloud Suite to version 25.1 or later immediately
• Review application and database logs for evidence of exploitation attempts
• Audit user accounts for suspicious activity, particularly those with database access
• Implement network segmentation to limit exposure of PAM infrastructure

Patch Information

Delinea has released a fix for this vulnerability in Cloud Suite version 25.1. Organizations should apply this update as soon as possible. Detailed release information is available in the Delinea Cloud Suite 25.1 Release Notes. Additional security information can be found at the Delinea Trust Center.

Workarounds

• Implement Web Application Firewall (WAF) rules to filter SQL Injection patterns as a temporary mitigation
• Restrict network access to Delinea services to trusted IP ranges and VPN-only access
• Increase monitoring and logging verbosity on affected systems until patching is complete
• Consider temporarily limiting user privileges where feasible to reduce potential impact
