Dolibarr 24.0.0 之前的版本存在一个基于对象级别授权失效的安全漏洞，该漏洞位于 REST API 中用于公司银行账户写入的接口路由。此漏洞允许拥有第三方创建权限的已认证攻击者，在无需对该公司拥有读取访问权限的情况下，创建、替换或删除任意公司的银行账户详情。攻击者可以注入由其控制的 IBAN（国际银行账户号码）作为收款方账户信息，这些被篡改的信息随后会被写入重新生成的 SEPA 贷记转账文件（SEPA credit-transfer files），从而导致对外付款被重定向至攻击者控制的账户。

Dolibarr < 24.0.0 REST API Broken Object-Level Authorization via Bank Account Routes
Source: CVE Program / CVE List V5
Vulnerability Description
Dolibarr before 24.0.0 contains a broken object-level authorization vulnerability in the REST API company bank account write routes that allows authenticated attackers with third-party creation rights to create, replace, or delete bank account details of any company without requiring read access to that company. Attackers can inject attacker-controlled IBANs as creditor accounts, which are then written into regenerated SEPA credit-transfer files, redirecting outgoing payments to attacker-controlled accounts.
