DescriptionCVE.org

A flaw has been found in code-projects Simple Stock System 1.0. The impacted element is an unknown function of the file /market/chatuser.php. This manipulation causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been published and may be used.

AnalysisAI

Stored cross-site scripting (XSS) in Simple Stock System 1.0 via the /market/chatuser.php endpoint allows remote attackers to inject malicious scripts without authentication. User interaction is required for payload execution. Publicly available exploit code exists; EPSS score of 0.08% indicates low statistical exploitation probability despite XSS classification.

Technical ContextAI

Simple Stock System 1.0, a PHP-based inventory management application, fails to properly sanitize user input in the /market/chatuser.php file before rendering it in web responses. This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), the standard category for reflected or stored XSS flaws. The attack vector is network-based (AV:N) with low complexity (AC:L), requiring only that a victim click a malicious link or visit a compromised page containing the injected payload. The low CVSS score (2.1) and minimal EPSS percentile (23%) reflect the requirement for user interaction (UI:P) and limited impact scope, though XSS can enable credential theft, session hijacking, or malware delivery depending on the application's role in the target environment.

RemediationAI

No vendor-released patch or upgraded version has been identified at time of analysis. Immediate remediation requires either upgrading to a patched version from the vendor (if available) or discontinuing use of Simple Stock System 1.0 and migrating to a maintained alternative. As interim compensating controls, implement HTML output encoding/escaping in the /market/chatuser.php file by applying PHP's htmlspecialchars() or htmlentities() functions to all user-supplied input before rendering in HTML contexts; validate and sanitize chat input using allowlists (e.g., permit only alphanumeric characters and select punctuation); deploy a Content Security Policy (CSP) header restricting inline script execution (Content-Security-Policy: default-src 'self'; script-src 'self') to limit XSS payload effectiveness even if injected; and monitor application logs for unusual characters in chatuser.php requests (e.g., <, >, quotes) that may indicate injection attempts. Note: CSP is a detective/preventive control and does not eliminate the vulnerability. The absence of vendor activity suggests this project may be unmaintained - security teams should plan migration timelines accordingly.
