Multiple LDAP injections vulnerabilities exist in SecurEnvoy MFA before 9.4.514 due to improper validation of user-supplied input. An unauthenticated remote attacker could exfiltrate data from Active Directory through blind LDAP injection attacks against the DESKTOP service exposed on the /secserver HTTP endpoint. This may include ms-Mcs-AdmPwd, which has a cleartext password for the Local Administrator Password Solution (LAPS) feature.

  • →Monitor POST requests to /secserver/? containing LDAP meta-characters in the USERID field (e.g., ')(sAMAccountName=*) as indicators of blind LDAP injection attempts against the DESKTOP service. ↗
  • →Use Shodan/FOFA queries 'title:"SecurEnvoy"' to identify exposed SecurEnvoy MFA instances that may be vulnerable.
  • →Exfiltration of the ms-Mcs-AdmPwd Active Directory attribute via LDAP injection yields cleartext LAPS local administrator passwords; monitor AD logs for unusual LDAP queries targeting this attribute. ↗
  • ·The vulnerability is unauthenticated and affects SecurEnvoy MFA versions before 9.4.514 only; patched instances (9.4.514+) are not affected. ↗
