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/unitofmeasurementcreate.php, in the unitofmeasurementid 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-2024-23861 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 due to improper neutralization of user-controlled input in the web application, specifically in the 'unitofmeasurementid' parameter of the /cupseasylive/unitofmeasurementcreate.php endpoint. Because the input is not sufficiently encoded or sanitized before being reflected in the web page, an attacker can craft a malicious URL containing executable script code. When an authenticated user clicks this URL, the embedded script executes in the context of the user's browser session. This can lead to theft of session cookies, allowing the attacker to hijack the user's session and potentially perform unauthorized actions within the application. The CVSS 3.1 base score of 8.2 reflects the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact on confidentiality is high (C:H), integrity is low (I:L), and availability is none (A:N). No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-79, which is a common web application security flaw related to improper input validation and output encoding during web page generation.

Potential Impact

For European organizations using Cups Easy (Purchase & Inventory) version 1.0, this vulnerability poses a significant risk to the confidentiality of sensitive business data. Attackers exploiting this XSS flaw can hijack authenticated sessions, potentially gaining unauthorized access to purchase and inventory records, financial data, or other proprietary information managed by the software. This could lead to data breaches, fraud, or manipulation of inventory records. The requirement for user interaction (clicking a malicious link) means phishing or social engineering campaigns could be used to target employees. Given the critical nature of purchase and inventory systems in supply chain and financial operations, disruption or data compromise could have cascading effects on business continuity and regulatory compliance, especially under GDPR where data protection is strictly enforced. The lack of a patch increases exposure time, and organizations may face reputational damage and legal consequences if exploited.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should immediately implement compensating controls while awaiting an official patch. These include: 1) Educating users to recognize and avoid clicking suspicious or unexpected links, especially those purporting to come from internal systems. 2) Employing web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'unitofmeasurementid' parameter. 3) Restricting access to the Cups Easy application to trusted networks and using VPNs or zero-trust network access to reduce exposure. 4) Monitoring web server logs for unusual requests or patterns indicative of XSS attempts. 5) Encouraging the vendor to release a patch that properly encodes or sanitizes user input in the affected parameter. 6) If feasible, temporarily disabling or restricting the vulnerable functionality until a fix is available. 7) Implementing Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers accessing the application. These measures go beyond generic advice by focusing on specific parameters and attack vectors relevant to this vulnerability.
