CVE Alert: CVE-2025-9511 – itsourcecode – Apartment Management System
CVE-2025-9511
A vulnerability was identified in itsourcecode Apartment Management System 1.0. This vulnerability affects unknown code of the file /visitor/addvisitor.php. Such manipulation of the argument ID leads to sql injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used.
AI Summary Analysis
Risk verdict
High risk: remote, unauthenticated SQL injection with a publicly available exploit; warrants prompt remediation.
Why this matters
Exploitation can expose or alter database content, potentially leaking resident data and undermining data integrity. With no user interaction required, adversaries could automate frequent payloads, degrade service, or pivot within the database to access other systems.
Most likely attack path
An attacker sends crafted input to the vulnerable addvisitor.php endpoint, exploiting SQL injection due to insufficient input validation. No authentication or user interaction is required, making automated scanning feasible. Successful exploitation can disclose or modify data and, in some configurations, enable broader access within the database scope.
Who is most exposed
Typical exposure is internet-facing deployments of itsourcecode Apartment Management System used by SMBs or property managers, often hosted on shared hosting or small cloud setups with weak network controls.
Detection ideas
- Logs show unusual requests to /visitor/addvisitor.php containing anomalous quotes or SQL syntax patterns.
- DB or app logs reveal syntax errors or query failures from that endpoint.
- Spike in HTTP 500s or failed queries correlated with addvisitor requests.
- Unusual data changes or mass data reads from the residents/visitors tables.
- WAF/IDS alerts on SQLi-like payloads targeting the endpoint.
Mitigation and prioritisation
- Apply vendor patch or upgrade to a fixed version; verify patch applicability in staging.
- Implement parameterised queries and strict input validation on addvisitor.php.
- Deploy a WAF signature to block SQLi patterns; monitor for related attempts.
- Restrict access to the endpoint (network ACLs, VPN, or 2FA where applicable); enforce least privilege for DB credentials.
- Schedule remediation in a formal change window; communicate impact to stakeholders.
If KEV true or EPSS ≥ 0.5, treat as priority 1.
