Ask Expert Script 3.0.5 XSS and SQL Injection

IdentifiersCVE-2019-25676CWE-79· Improper Neutralization of Input…

CVE-2019-25676 affects Ask Expert Script 3.0.5 and comprises two unauthenticated input-handling flaws in URL parameters. A cross-site scripting issue is present in categorysearch.php, where the cateid parameter can be manipulated to inject script tags into the application response. A SQL injection issue is present in list-details.php, where the view parameter can be manipulated to inject SQL code into backend database queries. The available description indicates both issues are remotely reachable over the network without authentication.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow an attacker to execute arbitrary JavaScript in the victim's browser context via the XSS vector and to extract database information via the SQL injection vector. Based on the provided CVSS and description, the primary impact is high confidentiality loss, with limited integrity impact and no stated availability impact.

Mitigation

If you can’t patch tonight, do this now.

If an immediate vendor fix is not available, restrict public access to the affected application, especially categorysearch.php and list-details.php, through network ACLs, reverse-proxy filtering, or authentication gates. Deploy WAF rules to detect and block common XSS payloads in cateid and SQL injection payloads in view. Minimize database privileges used by the application, monitor logs for suspicious parameter manipulation, and disable or isolate the application if exposure cannot be reduced.

Remediation

Patch, then assume compromise.

Upgrade Ask Expert Script from version 3.0.5 to a fixed release if one is available from the vendor. The vulnerable parameters should be remediated by implementing strict server-side input validation, context-appropriate output encoding for cateid in categorysearch.php, and parameterized queries or prepared statements for the view parameter in list-details.php. Review adjacent request parameters and database access paths for similar flaws.
