CVE-2024-37393
Published: 10 June 2024
Summary
CVE-2024-37393 is a high-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Securenvoy Multi-Factor Authentication Solutions. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2024-37393 affects SecurEnvoy MFA versions before 9.4.514 and stems from multiple LDAP injection flaws caused by insufficient validation of user-supplied input. The vulnerable component is the DESKTOP service reachable over the unauthenticated /secserver HTTP endpoint, which interacts with Active Directory.
An unauthenticated remote attacker can exploit the issue via blind LDAP injection to exfiltrate sensitive directory data, including the ms-Mcs-AdmPwd attribute that stores cleartext passwords used by the Local Administrator Password Solution (LAPS) feature. The vulnerability carries a CVSS 3.1 score of 7.5 reflecting network attack vector, low complexity, and high confidentiality impact without requiring privileges or user interaction.
Vendor references point to SecurEnvoy support resources for remediation guidance, while the associated EPSS score has remained flat at its peak value of 0.8466 since disclosure.
