Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and remediation of software flaws like CVE-2024-56841 through upgrading the vulnerable Mendix LDAP module.

SI-10 Information Input Validation good match

prevent

Requires validation of inputs to LDAP queries to directly prevent injection attacks that bypass username verification.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Enables vulnerability scanning to identify systems affected by the LDAP injection flaw in Mendix LDAP prior to V1.1.2.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

NVD Description

A vulnerability has been identified in Mendix LDAP (All versions < V1.1.2). Affected versions of the module are vulnerable to LDAP injection. This could allow an unauthenticated remote attacker to bypass username verification.

Deeper analysisAI

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.
