Summary

CVE-2024-56841 is a critical-severity LDAP Injection (CWE-90) vulnerability. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2024-56841 is an LDAP injection vulnerability affecting the Mendix LDAP module in all versions prior to V1.1.2. This flaw enables attackers to manipulate LDAP queries, potentially compromising authentication mechanisms within applications using the module.

An unauthenticated remote attacker can exploit this vulnerability over the network with high attack complexity and no user interaction required. Successful exploitation allows bypassing username verification, resulting in high impacts to confidentiality and integrity (CVSS 7.4: AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), such as unauthorized access to sensitive data or systems.

The Siemens security advisory at https://cert-portal.siemens.com/productcert/html/ssa-314390.html details mitigation, recommending an upgrade to Mendix LDAP V1.1.2 or later to address the vulnerability.
