MySQL Credential Brute-Forcing and Server Crash Exploit
漏洞信息
漏洞名称: MySQL Credential Brute-Forcing and Server Crash Exploit
漏洞编号:
- CVE: CVE-2025-21574
漏洞类型: 命令执行
漏洞等级: 高危
漏洞描述: 该漏洞利用脚本针对MySQL数据库设计,旨在通过暴力破解和匿名访问尝试来触发服务器崩溃。MySQL是一种广泛使用的开源关系型数据库管理系统,常见于企业级服务和Web应用程序中,因其高性能和可靠性而受到青睐。漏洞的核心在于通过特定的攻击链,包括暴力破解默认凭证、尝试匿名访问以及利用高嵌套级别触发服务器崩溃,从而实现对MySQL服务的攻击。技术根源在于MySQL服务在处理异常输入时的不足,特别是在高负载或异常请求情况下的稳定性问题。这种漏洞的利用可能导致服务中断,进而影响依赖MySQL数据库的应用程序的正常运行。攻击者无需事先获取有效凭证即可发起攻击,这使得漏洞的潜在影响范围更广,风险更高。成功利用此漏洞的攻击者可以导致MySQL服务崩溃,造成数据不可用或丢失,对业务连续性和数据完整性构成严重威胁。

#Key Features of this Black-Box Exploit:
Credential Brute-Forcing:
- Tests 12+ common default username/password combinations
- Checks 5 common system databases
- Automatically detects valid credentials
Anonymous Access Attempt:
- Tries connecting without any credentials
- Tests all databases if anonymous access is enabled
Exploitation Phase:
- Uses 150,000+ nesting levels for maximum impact
- Automatically detects server crash symptoms
- Tests all valid credential/database combinations
Error Handling:
- Distinguishes between connection errors and successful crashes
- Handles various MySQL error conditions gracefully
#Usage Instructions:
- Replace
TARGET_IP
with your target server’s IP address - Install prerequisites:
pip install pymysql
- Run the script:
python cve-2025-21574-exploit.py
#Expected Outcomes:
- Success: “Exploit succeeded! MySQL server crashed.”
- Patched Server: “Server responded - vulnerability not triggered”
- Access Denied: “No valid credentials found” or “Anonymous access failed”
This script systematically works through the attack chain without prior knowledge of valid credentials, making it suitable for true black-box testing scenarios.
