CVE-2024-23863: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Cups Easy Cups Easy (Purchase & Inventory)
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/taxstructuredisplay.php, in the description 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.
AI Analysis
Technical Summary
CVE-2024-23863 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-supplied input in the web application, specifically in the /cupseasylive/taxstructuredisplay.php endpoint where the 'description' parameter is not properly encoded or sanitized. This flaw allows an attacker to craft a malicious URL containing executable script code that, when visited by an authenticated user, executes in the user's browser context. The primary impact of this vulnerability is the potential theft of session cookies, which can lead to session hijacking and unauthorized access to the victim's account 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 confidentiality impact is high (C:H), integrity impact is low (I:L), and availability impact is none (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation leading to XSS. Given the nature of the vulnerability, attackers can leverage social engineering to trick authenticated users into clicking malicious links, potentially compromising sensitive business data and user accounts within the Cups Easy system.
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 information and user credentials. Successful exploitation could lead to session hijacking, allowing attackers to impersonate legitimate users and perform unauthorized actions such as modifying purchase orders, inventory data, or accessing confidential financial information. This could disrupt business operations, lead to financial losses, and damage organizational reputation. Since the vulnerability requires user interaction and valid authentication, insider threats or targeted phishing campaigns are likely attack vectors. The impact is particularly critical for organizations in sectors with stringent data protection requirements under GDPR, as unauthorized access to personal or financial data could result in regulatory penalties. Additionally, compromised credentials could be leveraged for lateral movement within corporate networks, escalating the threat beyond the initial application. The absence of a patch increases the urgency for organizations to implement interim mitigations to protect their assets.
Mitigation Recommendations
European organizations should immediately implement the following specific measures: 1) Employ web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'description' parameter in /cupseasylive/taxstructuredisplay.php. 2) Conduct user awareness training focused on recognizing phishing attempts and suspicious URLs to reduce the risk of users clicking malicious links. 3) Enforce strict session management policies, including setting HttpOnly and Secure flags on cookies to mitigate cookie theft via XSS. 4) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context. 5) Restrict access to the Cups Easy application to trusted networks or VPNs to limit exposure. 6) Monitor application logs for unusual activity or repeated access to the vulnerable endpoint with suspicious parameters. 7) Engage with the vendor for timely patch releases and apply updates as soon as they become available. 8) Consider deploying multi-factor authentication (MFA) to reduce the impact of compromised credentials. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter, user behavior, and session security.
