Low risk3th percentile - higher than 3% of all known CVEs
Summary
A network attacker positioned between UAA and its LDAP directory can impersonate the directory using any certificate from any trusted CA, then harvest the LDAP bind password and every end-user password sent during simple-bind authentication, and return forged group memberships that grant themselves admin scopes.
Risk Assessment
The organization is at risk of password theft for both users and administrators, potentially leading to unauthorized access to systems and data. An attacker could gain full control over the Cloud Foundry environment.
Recommendation
Immediately upgrade UAA to version v78.13.0 or later and cf-deployment to version v56.2.0 or later. In the interim, consider using LDAPS instead of StartTLS.

MISP contains an authentication bypass vulnerability in its LDAP and LinOTP authentication components due to insufficient validation of user-supplied credentials. An attacker knowing a valid directory user's email address could submit an empty password, which may be accepted by an LDAP server allowing unauthenticated binds. Additionally, in the LinOTP component, empty passwords could be checked against local MISP password hashes, and LDAP-provisioned accounts could be created with empty local passwords.

Original NVD description (English source)
A network attacker positioned between UAA and its LDAP directory can impersonate the directory using any certificate from any trusted CA, then harvest the LDAP bind password and every end-user password sent during simple-bind authentication, and return forged group memberships that grant themselves admin scopes. This affects every deployment that authenticates users against LDAP over StartTLS. Affected versions: UAA versions prior to v78.13.0; Cf-deployment versions prior to v56.2.0.
