Technical Analysis

CVE-2024-23864 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 'description' parameter of the /cupseasylive/countrylist.php endpoint. Because the input is not sufficiently encoded or sanitized before being included in the web page output, 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, enabling the attacker to steal session cookies or perform other malicious actions within the user's session. The CVSS v3.1 base score of 8.2 reflects the vulnerability's characteristics: it is remotely exploitable over the network without authentication (AV:N, PR:N), requires user interaction (UI:R), and impacts confidentiality significantly (C:H), with limited impact on integrity (I:L) and no impact on availability (A:N). The scope is changed (S:C), indicating that exploitation affects resources beyond the vulnerable component, such as user sessions. Although no public exploits are currently known in the wild, the vulnerability's nature and ease of exploitation make it a critical concern for organizations using this software. The lack of available patches at the time of reporting further increases risk exposure.

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 and user credentials. Successful exploitation could lead to session hijacking, allowing attackers to impersonate legitimate users, potentially gaining unauthorized access to purchase and inventory records. This could result in data leakage, unauthorized transactions, or manipulation of inventory data, impacting operational integrity and business continuity. Given the software's role in managing procurement and inventory, exploitation could disrupt supply chain processes or facilitate fraud. Additionally, compromised user sessions could be leveraged to escalate privileges or move laterally within the organization's network. The impact extends beyond individual users to the organization's reputation and compliance posture, especially under GDPR requirements for protecting personal and business data. The requirement for user interaction (clicking a malicious link) means phishing or social engineering campaigns could be used to target employees, increasing the attack surface.

Mitigation Recommendations

Organizations should immediately assess their use of Cups Easy (Purchase & Inventory) version 1.0 and implement compensating controls until an official patch is available. Specific recommendations include: 1) Restrict access to the /cupseasylive/countrylist.php endpoint via web application firewalls (WAFs) or network controls to block suspicious or malformed requests containing script payloads. 2) Educate users about the risks of clicking untrusted links, emphasizing caution with URLs received via email or messaging platforms. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context. 4) Monitor web server and application logs for unusual request patterns targeting the vulnerable parameter. 5) If possible, apply input validation and output encoding at the application level to sanitize the 'description' parameter, or disable the vulnerable functionality temporarily. 6) Use multi-factor authentication (MFA) to reduce the impact of stolen session credentials. 7) Regularly review and update session management policies to limit session lifetime and scope. Organizations should also engage with the vendor for timely patch releases and apply updates as soon as they become available.
