CVE-2026-1198 identifies a SQL Injection vulnerability in Simple.ERP, a product developed by Simple SA. The vulnerability exists in the search functionality within the "Obroty na kontach" window, where input fields do not properly sanitize or neutralize special SQL elements. This improper neutralization (CWE-89) allows an authenticated attacker with low privileges to craft malicious SQL queries that the backend database executes. The flaw enables attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or disruption of database operations. The vulnerability does not require user interaction and can be exploited remotely over the network. The affected versions are those prior to 6.30@A04.4_u06, where the vendor has released a fix. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no need for user interaction, and high impact on confidentiality and integrity, but no impact on availability. No known exploits have been reported in the wild yet, but the vulnerability's nature makes it a critical concern for organizations using this ERP system.

The SQL Injection vulnerability in Simple.ERP can have severe consequences for organizations. Exploitation can lead to unauthorized disclosure of sensitive business data, including financial records and customer information, compromising confidentiality. Attackers may also alter or delete critical data, affecting data integrity and potentially disrupting business operations. Since the vulnerability requires only authenticated access with low privileges, insider threats or compromised user accounts could be leveraged to exploit this flaw. The lack of user interaction requirement and network accessibility increase the risk of automated or remote exploitation. Organizations relying on Simple.ERP for financial and operational management face risks of data breaches, regulatory non-compliance, and reputational damage. The absence of known exploits currently provides a window for proactive patching and mitigation before widespread attacks occur.

To mitigate CVE-2026-1198, organizations should immediately apply the vendor-provided patch available in Simple.ERP version 6.30@A04.4_u06 or later. In addition to patching, implement strict input validation and sanitization on all user-supplied data, especially in search and query interfaces. Employ parameterized queries or prepared statements to prevent SQL Injection. Conduct a thorough code review and security testing of all database interaction points within the ERP system. Limit user privileges to the minimum necessary to reduce the impact of compromised accounts. Monitor database logs and application behavior for unusual query patterns indicative of injection attempts. Consider deploying Web Application Firewalls (WAFs) with SQL Injection detection rules as an additional layer of defense. Regularly train developers and administrators on secure coding practices and vulnerability management. Finally, maintain an incident response plan to quickly address any exploitation attempts.
