CVE-2024-49620 is a Blind SQL Injection vulnerability identified in the FERMA.ru.net product, specifically versions up to and including 1.3.3. The vulnerability stems from improper neutralization of special elements in SQL commands within the ferma-ru-net-checkout component, allowing attackers to inject arbitrary SQL code. Blind SQL Injection means attackers cannot directly see query results but can infer data by observing application behavior or response timing. This type of injection can be exploited to extract sensitive information such as user credentials, financial data, or internal configurations, or to modify or delete data within the backend database. The vulnerability does not require prior authentication, increasing the attack surface, and can be triggered remotely by sending crafted input to vulnerable endpoints. Although no public exploits are currently known, the presence of this vulnerability in a web-facing checkout system suggests a high risk of exploitation once details become widely known. The lack of an official patch at the time of publication increases urgency for organizations to implement compensating controls. The vulnerability was published on October 20, 2024, and assigned by Patchstack. The absence of a CVSS score requires an independent severity assessment based on impact and exploitability factors.

The potential impact of CVE-2024-49620 is significant for organizations using FERMA.ru.net, particularly those relying on the affected checkout system for e-commerce or transaction processing. Successful exploitation can lead to unauthorized disclosure of sensitive data, including customer information, payment details, and internal business data, undermining confidentiality. Attackers could also manipulate database contents, affecting data integrity and potentially causing financial loss or operational disruption. Since the vulnerability allows remote exploitation without authentication, it broadens the attack surface and increases the likelihood of automated attacks or exploitation by opportunistic threat actors. The blind nature of the injection complicates detection but does not reduce the severity, as attackers can still extract valuable information over time. Organizations may face regulatory penalties, reputational damage, and loss of customer trust if exploited. The absence of known exploits currently provides a window for mitigation, but the risk escalates as exploit code becomes available.

To mitigate CVE-2024-49620, organizations should prioritize upgrading FERMA.ru.net to a version that addresses this vulnerability once available from the vendor. In the absence of an official patch, implement input validation and sanitization on all user-supplied data, especially in the checkout module, to neutralize special SQL characters and prevent injection. Employ parameterized queries or prepared statements in the application code to separate SQL logic from data inputs, effectively blocking injection attempts. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoints. Conduct thorough code reviews and security testing focusing on SQL injection vectors. Monitor application logs and database query patterns for anomalies indicative of injection attempts. Limit database user privileges to the minimum necessary to reduce the impact of a successful injection. Finally, educate developers and administrators about secure coding practices and the risks of SQL injection to prevent future vulnerabilities.
