CVE-2026-40830
Description
A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the admin.mbnetj.php files UpdateParam function due to improper neutralization of special elements in a SQL UPDATE command allowing for reading the whole database and changing values in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
High-privileged remote attacker exploits unauthenticated SQL injection in mbCONNECT24's admin.mbnetj.php to read database and modify non-critical tables.
Vulnerability
An SQL injection vulnerability exists in the UpdateParam function of admin.mbnetj.php in mbCONNECT24/mymbCONNECT24 [1]. The function does not properly neutralize special elements used in a SQL UPDATE command, allowing an attacker with high privileges to execute arbitrary SQL statements. The exact affected versions are not detailed in available references.
Exploitation
An attacker with high privileges can send a crafted request to the UpdateParam endpoint without additional authentication, exploiting the SQL injection to execute arbitrary SQL commands. No user interaction is required.
Impact
Successful exploitation allows the attacker to read the entire database, resulting in a total loss of confidentiality, and to modify values in a non-critical table, causing a partial loss of integrity [1].
Mitigation
As of the publication date (2026-05-27), no fixed version has been released. Users should apply network segmentation and restrict access to the admin interface as a workaround. Monitor vendor advisories for updates [1].
