Mô tả

Impact

The LDAP authentication adapter is vulnerable to LDAP injection. User-supplied input (authData.id) is interpolated directly into LDAP Distinguished Names (DN) and group search filters without escaping special characters. This allows an attacker with valid LDAP credentials to manipulate the bind DN structure and to bypass group membership checks. This enables privilege escalation from any authenticated LDAP user to a member of any restricted group.

The vulnerability affects Parse Server deployments that use the LDAP authentication adapter with group-based access control.

Patches

The vulnerability is fixed by escaping user input before interpolation into DN strings (per RFC 4514) and LDAP filter strings (per RFC 4515).

Workarounds

There is no known workaround.

Mô tả của NVD

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.13 and 8.6.26, the LDAP authentication adapter is vulnerable to LDAP injection. User-supplied input (authData.id) is interpolated directly into LDAP Distinguished Names (DN) and group search filters without escaping special characters. This allows an attacker with valid LDAP credentials to manipulate the bind DN structure and to bypass group membership checks. This enables privilege escalation from any authenticated LDAP user to a member of any restricted group. The vulnerability affects Parse Server deployments that use the LDAP authentication adapter with group-based access control. This vulnerability is fixed in 9.5.2-alpha.13 and 8.6.26.
