CVE-2025-46460 is a critical SQL Injection vulnerability (CWE-89) identified in the Detheme Easy Guide product, affecting versions up to 1.0.0. SQL Injection occurs when an application improperly neutralizes special elements in SQL commands, allowing an attacker to inject malicious SQL code. This vulnerability enables remote attackers to execute arbitrary SQL queries on the backend database without requiring authentication or user interaction. The CVSS 3.1 base score of 9.3 reflects the high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality is high (C:H), allowing potential data disclosure, while integrity impact is none (I:N), and availability impact is low (A:L), suggesting limited disruption to service but significant data exposure risk. Although no known exploits are currently reported in the wild, the ease of exploitation and critical impact make this a significant threat. The vulnerability likely arises from insufficient input validation or parameterized query usage in Easy Guide's database interactions, allowing attackers to manipulate SQL statements to extract sensitive data or perform unauthorized read operations.

For European organizations using Detheme Easy Guide, this vulnerability poses a substantial risk of data breaches, particularly exposing sensitive or confidential information stored in backend databases. The high confidentiality impact means attackers could extract user data, business intelligence, or other critical information, potentially leading to regulatory non-compliance under GDPR and reputational damage. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the likelihood of automated attacks or scanning by malicious actors. Although the availability impact is low, the data confidentiality breach alone can have severe legal and financial consequences. Organizations in sectors such as finance, healthcare, government, and critical infrastructure in Europe are especially vulnerable due to the sensitivity of their data and strict regulatory environments. Additionally, the changed scope indicates that the vulnerability could affect interconnected systems or services, amplifying the potential damage.

To mitigate CVE-2025-46460, European organizations should immediately assess their use of Detheme Easy Guide and prioritize patching once an official fix is released by the vendor. In the absence of a patch, organizations should implement the following specific measures: 1) Conduct a thorough code review of all SQL query constructions within Easy Guide to identify and remediate unsafe dynamic SQL usage; 2) Employ parameterized queries or prepared statements to ensure proper input sanitization and prevent injection; 3) Implement Web Application Firewalls (WAFs) with custom rules targeting SQL Injection patterns specific to Easy Guide's query structure; 4) Restrict database user permissions to the minimum necessary, limiting the impact of any successful injection; 5) Monitor database logs and application logs for unusual query patterns or error messages indicative of injection attempts; 6) Conduct penetration testing focused on SQL Injection vectors to validate the effectiveness of mitigations; 7) Educate developers and administrators on secure coding practices related to database interactions. These targeted actions go beyond generic advice by focusing on the specific product and vulnerability characteristics.
