CVE-2024-7488 is a medium severity vulnerability classified under CWE-190 (Integer Overflow or Wraparound) and CWE-1284 (Improper Validation of Specified Quantity in Input) affecting RestApp Inc.'s Online Ordering System version 8.2.1. The vulnerability stems from the system's failure to properly validate the quantity input field, allowing an attacker to supply specially crafted integer values that cause an overflow or wraparound. This can lead to incorrect processing of order quantities, potentially enabling attackers to manipulate order data, bypass quantity restrictions, or cause unexpected behavior in the ordering workflow. The flaw does not require authentication or user interaction and can be exploited remotely over the network. The vulnerability was introduced in version 8.2.1 and has been resolved in version 8.2.2. The CVSS 3.1 base score is 5.3, reflecting a network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality impact, limited integrity impact, and no availability impact. No public exploits have been reported to date. The vulnerability primarily threatens the integrity of order data, which could lead to financial discrepancies or operational disruptions if exploited.

For European organizations, especially those in retail, hospitality, and food delivery sectors using RestApp's Online Ordering System version 8.2.1, this vulnerability poses a risk of order manipulation. Attackers could exploit the integer overflow to alter order quantities, potentially causing financial losses, inventory mismanagement, or disruption of customer service. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could undermine trust in the ordering system and lead to downstream operational issues. Organizations relying on automated order processing may face challenges reconciling orders or detecting fraudulent transactions. Given the lack of authentication or user interaction requirements, the attack surface is broad, increasing the likelihood of exploitation if the vulnerable version is exposed to the internet. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

The primary mitigation is to upgrade the RestApp Online Ordering System from version 8.2.1 to 8.2.2 or later, where the vulnerability is fixed. Organizations should implement strict input validation and sanitization on quantity fields to prevent integer overflow or wraparound conditions. Employing application-layer firewalls or web application firewalls (WAFs) with custom rules to detect anomalous quantity inputs can provide additional protection. Regularly audit and monitor order data for irregularities that may indicate exploitation attempts. Network segmentation and limiting external exposure of the ordering system can reduce attack surface. Additionally, coordinate with RestApp support for any vendor-specific patches or guidance. Incorporating anomaly detection in order processing workflows can help identify suspicious activity early. Finally, ensure that software inventory and patch management processes are robust to prevent running vulnerable versions in production.
