CVE-2019-25663 Overview
CVE-2019-25663 is a SQL injection vulnerability [CWE-89] in SuiteCRM 7.10.7, an open-source customer relationship management (CRM) platform developed by SalesAgility. Authenticated attackers can manipulate database queries by injecting SQL code through the parentTab parameter in the email module. The flaw allows boolean-based blind SQL injection via crafted GET requests, enabling extraction of sensitive database contents including credentials, customer records, and configuration data.
Critical Impact
Authenticated attackers can exfiltrate confidential CRM data — including customer records and stored credentials — by sending malicious GET requests to the email module.
Affected Products
- SuiteCRM 7.10.7
- SalesAgility SuiteCRM (versions matching cpe:2.3:a:salesagility:suitecrm)
- Deployments exposing the email module to authenticated users

Technical Details for CVE-2019-25663
Vulnerability Analysis
The vulnerability resides in the email module of SuiteCRM 7.10.7, where the parentTab GET parameter is concatenated into a SQL query without proper sanitization or parameterization. An authenticated user can supply boolean-based SQL injection payloads through this parameter to alter query logic.
Because the injection point is boolean-based blind, attackers infer data by observing differential responses between true and false conditions. Repeated requests with conditional payloads allow systematic extraction of database schema, table contents, and sensitive records. The vulnerability is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.
Root Cause
The root cause is the direct inclusion of user-supplied input from the parentTab parameter into a SQL statement without prepared statements or input validation. SuiteCRM's email module accepts the parameter from the HTTP GET request and passes it through to the database layer, breaking the trust boundary between client input and query construction.
Attack Vector
Exploitation requires valid authentication to the SuiteCRM instance and network access to the application. The attacker sends a GET request to the email module endpoint with a malicious parentTab value containing SQL injection syntax. Boolean-based payloads such as AND 1=1 versus AND 1=2 reveal data through response differences.
Technical exploitation details and a working proof-of-concept are documented in the Exploit-DB #46310 entry and the VulnCheck SQL Injection Advisory.
Detection Methods for CVE-2019-25663
Indicators of Compromise
- GET requests to SuiteCRM email module URLs containing SQL keywords such as SELECT, UNION, SLEEP, or AND in the parentTab parameter
- Repetitive requests from a single authenticated session with incrementing or boolean-style payloads in parentTab
- Unusual database query latency or error log entries from the SuiteCRM MySQL backend correlated with email module access
Detection Strategies
- Inspect web server access logs for parentTab= values that contain SQL syntax, URL-encoded quotes (%27), or comment markers (--, #)
- Deploy a Web Application Firewall (WAF) rule that flags non-alphanumeric content in the parentTab parameter
- Correlate authenticated SuiteCRM sessions with anomalously high request volumes to the email module
Monitoring Recommendations
- Enable MySQL general query logging or slow query logging during incident response to identify injected query patterns
- Forward SuiteCRM application and web server logs to a centralized logging platform for query-string analysis
- Alert on authenticated user accounts generating sustained boolean-pattern traffic against the email module
How to Mitigate CVE-2019-25663
Immediate Actions Required
- Upgrade SuiteCRM to a version later than 7.10.7 that addresses the parentTab SQL injection
- Audit existing user accounts and revoke unused or stale credentials to limit the authenticated attack surface
- Review database logs and access logs for indicators of prior exploitation before patching
Patch Information
No specific vendor advisory URL is published in the enriched CVE data. Administrators should consult the SuiteCRM Download Page for current releases and the VulnCheck SQL Injection Advisory for remediation guidance. Upgrading to the latest supported SuiteCRM release is the recommended path.
Workarounds
- Restrict access to the SuiteCRM application using network-level controls such as VPN or IP allowlists
- Deploy WAF rules that block or sanitize SQL metacharacters in the parentTab GET parameter
- Enforce least-privilege database accounts so the SuiteCRM service user cannot read unrelated schemas
# Example ModSecurity rule to block SQL syntax in parentTab parameter
SecRule ARGS:parentTab "@rx (?i)(union|select|sleep|benchmark|--|#|';)" \
"id:1002663,phase:2,deny,status:403,msg:'Possible SQLi in parentTab (CVE-2019-25663)'"
