CVE-2025-26943 identifies a Blind SQL Injection vulnerability in the Easy Quotes software developed by Jürgen Müller, affecting versions up to and including 1.2.2. The root cause is improper neutralization of special characters in SQL commands, which allows attackers to craft malicious input that is executed by the backend database. Blind SQL Injection means attackers cannot directly see query results but can infer data through response behavior or timing. This vulnerability enables attackers to extract sensitive information, manipulate database contents, or disrupt service availability. The vulnerability does not require authentication, increasing its risk profile, and no patches or fixes have been released at the time of publication. Although no active exploits have been reported, the vulnerability's nature and ease of exploitation make it a significant threat. The lack of a CVSS score necessitates a severity assessment based on impact and exploitability. The vulnerability affects all installations of Easy Quotes up to version 1.2.2, which may be used in various content management or quoting systems, potentially exposing a wide range of organizations. The absence of patches means organizations must implement immediate mitigations to protect their systems.

The potential impact of CVE-2025-26943 is substantial for organizations using Easy Quotes. Exploitation could lead to unauthorized disclosure of sensitive data stored in the backend database, including user information, quotes, or other proprietary content. Attackers could also alter or delete data, undermining data integrity and trustworthiness. In some cases, exploitation may cause denial of service by triggering database errors or locking resources. Since the vulnerability is a Blind SQL Injection, attackers can systematically extract data over time, increasing the risk of prolonged undetected breaches. The lack of authentication requirements broadens the attack surface, allowing external attackers to target vulnerable systems remotely. Organizations in sectors relying on Easy Quotes for content management, publishing, or customer interaction may face reputational damage, regulatory penalties, and operational disruptions if exploited. The absence of known exploits currently provides a window for proactive defense, but the risk remains high due to the vulnerability's nature.

To mitigate CVE-2025-26943, organizations should immediately implement strict input validation and sanitization on all user-supplied data interacting with SQL queries in Easy Quotes. Employ parameterized queries or prepared statements to ensure that SQL commands are constructed safely, preventing injection of malicious code. Until an official patch is released, consider deploying Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting Easy Quotes. Conduct thorough code reviews and security testing focusing on database interaction points within the application. Monitor application logs and database activity for unusual patterns indicative of injection attempts or exploitation. Limit database user privileges to the minimum necessary to reduce potential damage from successful attacks. If feasible, isolate the Easy Quotes application environment to contain potential breaches. Stay informed about vendor updates and apply patches promptly once available. Additionally, educate developers and administrators about secure coding practices to prevent similar vulnerabilities in the future.
