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/locationmodify.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.

Technical Analysis

CVE-2024-23872 is a high-severity Cross-Site Scripting (XSS) vulnerability identified in version 1.0 of Cups Easy (Purchase & Inventory), a software product used for managing purchase and inventory operations. The vulnerability arises from improper neutralization of user-supplied input in the 'description' parameter of the /cupseasylive/locationmodify.php endpoint. Specifically, the application fails to adequately encode or sanitize this input before rendering it in a web page, allowing an attacker to inject malicious scripts. Exploitation requires the attacker to craft a specially designed URL containing malicious JavaScript code and trick an authenticated user into visiting it. Upon execution, the injected script can steal the victim's session cookie credentials, potentially enabling session hijacking and unauthorized access to the victim's account within the application. The CVSS v3.1 base score is 8.2, reflecting a high severity due to the network attack vector, low attack complexity, no privileges required, but requiring user interaction. The scope is changed, indicating that the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality is high, as session cookies can be stolen, while integrity impact is low and availability is not affected. No known public exploits have been reported yet, and no patches are currently linked, indicating that mitigation may rely on workarounds or vendor updates in the near future.

Potential Impact

For European organizations using Cups Easy (Purchase & Inventory) version 1.0, this vulnerability poses a significant risk to the confidentiality of user sessions and potentially sensitive business data managed within the application. If exploited, attackers could hijack authenticated sessions, leading to unauthorized access to purchase and inventory records, manipulation of data, or further lateral movement within the organization's network. This could result in financial losses, disruption of supply chain management, and exposure of proprietary or personal data. Given that the attack requires user interaction (clicking a malicious link), phishing campaigns targeting employees are a likely exploitation vector. The vulnerability's impact is amplified in environments where Cups Easy is integrated with other critical business systems or where session cookies grant broad access privileges. Additionally, the lack of a patch at this time increases the window of exposure. European organizations must be vigilant, especially those in sectors relying heavily on inventory and purchase management software, such as manufacturing, retail, and logistics.

Mitigation Recommendations

1. Immediate mitigation should focus on user awareness and training to recognize and avoid suspicious links, especially those purporting to be related to inventory or purchase management tasks. 2. Implement strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the application context. 3. Use web application firewalls (WAFs) to detect and block malicious payloads targeting the vulnerable parameter. 4. Restrict access to the Cups Easy application to trusted networks or VPNs to reduce exposure to external attackers. 5. Monitor application logs for unusual activity or repeated access to the vulnerable endpoint with suspicious parameters. 6. Engage with the vendor to obtain patches or updates as soon as they become available. 7. If feasible, perform input validation and output encoding on the server side as an interim fix, possibly by customizing the application or deploying reverse proxies that sanitize inputs. 8. Enforce session management best practices such as using HttpOnly and Secure flags on cookies to limit cookie theft impact. 9. Conduct regular security assessments and penetration tests focusing on web application vulnerabilities to identify and remediate similar issues proactively.
