CVE-2025-0616: B2B Netsis Panel SQL Injection Vulnerability

CVE-2025-0616 Overview

CVE-2025-0616 is a SQL injection vulnerability affecting the B2B - Netsis Panel product from Teknolojik Center Telecommunication Industry Trade Co. Ltd. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. Unauthenticated attackers can inject crafted SQL statements through network-facing inputs to manipulate backend database queries. The issue affects all B2B - Netsis Panel versions through build 20251003. According to the NVD entry, the vendor was contacted before disclosure but did not respond. No patch is currently referenced.

Critical Impact

Network-accessible SQL injection allows unauthenticated attackers to read sensitive database content and tamper with stored data without user interaction.

Affected Products

• Teknolojik Center B2B - Netsis Panel through build 20251003
• Earlier B2B - Netsis Panel deployments exposing the vulnerable query interface
• Internet-facing instances accessible without authentication

Discovery Timeline

Technical Details for CVE-2025-0616

Vulnerability Analysis

The vulnerability is classified under [CWE-89], improper neutralization of special elements used in an SQL command. User-supplied input reaches database query construction without adequate sanitization or parameterization. Attackers exploit this by submitting crafted payloads through HTTP request parameters consumed by the B2B - Netsis Panel application. Successful exploitation exposes confidential database content and permits limited modification of stored records. The CVSS vector indicates network reachability, no privileges required, and no user interaction, making the attack surface broad for any internet-exposed instance.

Root Cause

The application concatenates untrusted input directly into SQL statements rather than using prepared statements with bound parameters. This allows attacker-controlled metacharacters such as quotes, comments, and statement terminators to alter query semantics. Missing input validation and absence of an allowlist for expected input shapes amplify the issue.

Attack Vector

An unauthenticated remote attacker sends HTTP requests containing SQL metacharacters to vulnerable endpoints in the B2B - Netsis Panel. The injected payload modifies the resulting query to extract data via UNION-based, error-based, or boolean-based blind techniques. Refer to the USOM Security Notification TR-25-0311 for the official advisory. No verified public proof-of-concept code is currently available.

Detection Methods for CVE-2025-0616

Indicators of Compromise

• HTTP request parameters containing SQL metacharacters such as ', --, ;, UNION SELECT, or OR 1=1 directed at B2B - Netsis Panel endpoints
• Web server access logs showing repeated parameter fuzzing from a single source
• Database error responses returned to the client indicating malformed query execution
• Anomalous outbound data volumes from the application server following crafted requests

Detection Strategies

• Inspect web application firewall (WAF) logs for SQL injection signatures targeting Netsis Panel URLs
• Correlate database query logs with web request logs to identify unexpected SELECT, UNION, or INFORMATION_SCHEMA queries
• Hunt for sessions where a single client triggers high volumes of database errors

Monitoring Recommendations

• Enable verbose query logging on the backend database for the application service account
• Forward web, WAF, and database telemetry to a centralized SIEM for cross-source correlation
• Alert on access to sensitive tables outside normal application query patterns

How to Mitigate CVE-2025-0616

Immediate Actions Required

• Restrict network access to the B2B - Netsis Panel using IP allowlisting or VPN until a vendor patch is released
• Deploy WAF rules that block common SQL injection payloads against panel endpoints
• Audit database accounts used by the application and revoke unnecessary privileges to limit blast radius
• Review recent web and database logs for prior exploitation attempts

Patch Information

The vendor has not published a fix referenced in the NVD entry, and the advisory notes the vendor did not respond to disclosure outreach. Operators should monitor the USOM Security Notification TR-25-0311 and vendor channels for updated guidance.

Workarounds

• Place the application behind a reverse proxy enforcing strict input validation on query parameters
• Apply WAF signatures specifically targeting SQL injection patterns such as tautologies and union-based payloads
• Reduce the application database account to read-only or schema-scoped permissions where business logic permits
• Disable internet exposure of the panel where remote access is not strictly required

# Example ModSecurity rule to block common SQLi tokens on the panel path
SecRule REQUEST_URI "@beginsWith /netsis" \
    "id:1009000,phase:2,deny,status:403,msg:'Block SQLi attempt on Netsis Panel',\
    chain"
    SecRule ARGS "@rx (?i)(union(\s|/\*.*\*/)+select|('|\")\s*or\s+1=1|--|;--|/\*!)" \
