Product: Cups Easy (Purchase & Inventory)

Description

A vulnerability has been reported in Cups Easy (Purchase & Inventory), version 1.0, whereby user-controlled inputs are not sufficiently encoded, resulting in a Cross-Site Scripting (XSS) vulnerability via /cupseasylive/grncreate.php, in the grndate parameter. Exploitation of this vulnerability could allow a remote attacker to send a specially crafted URL to an authenticated user and steal their session cookie credentials.

Technical Analysis

CVE-2024-23887 is a high-severity Cross-Site Scripting (XSS) vulnerability identified in version 1.0 of Cups Easy (Purchase & Inventory), a software product used for purchase and inventory management. The vulnerability arises from improper neutralization of user-supplied input in the web application, specifically in the 'grndate' parameter of the /cupseasylive/grncreate.php endpoint. Because this parameter is not sufficiently encoded or sanitized, an attacker can craft a malicious URL containing executable script code. When an authenticated user accesses this URL, the injected script executes in their browser context. This can lead to theft of session cookies, enabling the attacker to hijack the user's session and potentially perform unauthorized actions within the application. The CVSS 3.1 base score is 8.2, reflecting the vulnerability's network attack vector, low attack complexity, no privileges required, but requiring user interaction (clicking the malicious link). The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality is high due to session cookie theft, integrity impact is low, and availability is not affected. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was assigned and published by INCIBE in January 2024.

Potential Impact

For European organizations using Cups Easy (Purchase & Inventory) version 1.0, this vulnerability poses a significant risk. Attackers can exploit the XSS flaw to hijack sessions of authenticated users, potentially gaining unauthorized access to sensitive purchase and inventory data. This could lead to data breaches, manipulation of inventory records, fraudulent transactions, or disruption of procurement processes. Given the nature of inventory and purchase systems, compromised sessions could facilitate financial fraud or supply chain sabotage. The confidentiality of business-critical information is at high risk, while integrity could be moderately impacted if attackers alter data. Availability is unlikely to be directly affected by this vulnerability. Organizations in Europe must be vigilant, especially those in sectors with stringent data protection regulations like GDPR, as exploitation could lead to regulatory penalties and reputational damage.

Mitigation Recommendations

Since no official patches are currently available, European organizations should implement immediate compensating controls. First, apply strict input validation and output encoding on the 'grndate' parameter at the web application firewall (WAF) or reverse proxy level to block malicious payloads. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Educate users to avoid clicking suspicious links and implement multi-factor authentication (MFA) to reduce the impact of session hijacking. Monitor web server logs for unusual requests targeting /cupseasylive/grncreate.php and anomalous user behavior indicative of session compromise. Segregate the Cups Easy application network segment and limit access to trusted users only. Once the vendor releases a patch, prioritize its deployment. Additionally, review session management practices to ensure cookies have secure, HttpOnly, and SameSite attributes set to mitigate cookie theft risks.
