Parse Server has an LDAP injection via unsanitized user input in DN and group filter construction

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.

Parse Server 注入漏洞

Parse Server是Parse Platform开源的一个开源后端，可以部署到任何可以运行 Node.js 的基础设施。 Parse Server 9.5.2-alpha.13之前版本和8.6.26之前版本存在注入漏洞，该漏洞源于LDAP身份验证适配器对用户输入处理不当，可能导致LDAP注入和权限提升。
