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 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover LDAP injection flaws through static analysis or crafted test cases.
Input validation directly stops untrusted data from reaching an LDAP query builder without neutralization of special characters.
Secure engineering principles require safe query construction and escaping that structurally prevents LDAP injection.

Security testing in development catches LDAP injection via dynamic analysis or fuzzing, but does not prevent it at the source.
Secure development lifecycle mandates input validation and query construction practices that directly prevent LDAP injection.
Application security requirements include explicit rules for safe construction of directory queries, mitigating LDAP injection.
Secure coding standards require proper neutralization of LDAP special characters, directly eliminating this weakness.
Secure architecture principles encourage safe query interfaces but do not prescribe the specific coding controls needed for LDAP injection.
