CVE-2025-1389 Overview
CVE-2025-1389 is a SQL Injection vulnerability [CWE-89] affecting Orca HCM, a human capital management platform from Learning Digital. Authenticated attackers with regular user privileges can inject arbitrary SQL commands into the application. Successful exploitation allows attackers to read, modify, and delete arbitrary database contents. The flaw was disclosed through the Taiwan Computer Emergency Response Team (TWCERT) and affects deployments of Orca HCM exposed to internal users or wider networks.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the Orca HCM database, leading to full compromise of confidentiality, integrity, and availability of stored HR, payroll, and employee data.
Affected Products
- Learning Digital Orca HCM (all versions prior to the vendor-supplied fix)
- Deployments using the affected learningdigital:orca_hcm component
- On-premises installations exposed to authenticated internal users
Discovery Timeline
- 2025-02-17 - CVE-2025-1389 published to the National Vulnerability Database (NVD)

Technical Details for CVE-2025-1389
Vulnerability Analysis
The vulnerability is a classic SQL Injection flaw [CWE-89] in Orca HCM. User-supplied input is concatenated into SQL statements without proper parameterization or sanitization. An attacker authenticated as a regular, low-privileged user can inject crafted SQL syntax through application request parameters. The injected payload is executed within the database context used by the application.
Successful exploitation breaks all three core security properties. Attackers can exfiltrate sensitive HR records, modify payroll or access control tables, and destroy data through DROP or DELETE statements. Because Orca HCM stores personally identifiable information (PII) and salary data, the business impact is significant.
Root Cause
The root cause is improper neutralization of special elements used in an SQL command. Application code constructs queries by concatenating untrusted input directly into SQL strings. Parameterized queries, prepared statements, or stored procedures are not used consistently across affected endpoints.
Attack Vector
The attack vector is network-based and requires authentication at the standard user level. No social engineering or user interaction is required after authentication. An attacker submits crafted input through a vulnerable HTTP parameter, and the application server passes the malicious SQL to the backend database for execution. See the TWCERT Security Advisory for additional vendor-coordinated technical details.
Detection Methods for CVE-2025-1389
Indicators of Compromise
- Unexpected database queries containing SQL meta-characters such as ', --, UNION SELECT, or OR 1=1 in Orca HCM application logs
- Anomalous read volumes from the Orca HCM database service account, especially against employee, payroll, or auth tables
- HTTP requests from authenticated low-privilege users containing encoded SQL keywords in query strings or POST bodies
- Unusual INSERT, UPDATE, or DELETE activity originating from web application sessions outside of normal business workflows
Detection Strategies
- Enable verbose query logging on the Orca HCM database and review for syntactically anomalous statements
- Deploy a web application firewall (WAF) with SQL injection signatures in front of the Orca HCM web interface
- Correlate authenticated user session activity with database query patterns to identify privilege misuse
- Hunt for outbound data transfers that correlate with suspicious authenticated HCM sessions
Monitoring Recommendations
- Continuously monitor application logs for HTTP 500 responses tied to malformed SQL, which often indicate probing
- Alert on database errors referencing syntax exceptions originating from Orca HCM service accounts
- Track failed and successful logins to Orca HCM to identify accounts that may be used as injection footholds
- Baseline normal query patterns and alert on deviations such as schema enumeration through information_schema
How to Mitigate CVE-2025-1389
Immediate Actions Required
- Apply the vendor-supplied patch from Learning Digital as referenced in the TWCERT Security Notice
- Restrict network access to Orca HCM so the application is reachable only from trusted internal segments or VPN
- Audit Orca HCM user accounts and disable inactive or unnecessary low-privilege accounts that could be abused
- Rotate database service account credentials used by Orca HCM after patching
Patch Information
Learning Digital has released a fixed version of Orca HCM addressing the SQL Injection flaw. Customers should consult the TWCERT Security Advisory and contact the vendor directly to obtain the corrected build and upgrade guidance. Apply the update to all production, staging, and disaster recovery instances.
Workarounds
- Deploy a WAF rule set that blocks common SQL Injection payloads targeting Orca HCM endpoints until patching completes
- Apply least-privilege controls to the database account used by Orca HCM, removing DROP, ALTER, and cross-schema privileges where possible
- Limit application access to authenticated users on a need-to-use basis and enforce session monitoring
- Enable database activity monitoring (DAM) to detect and block injection payloads at the data tier
