Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack-based buffer overflow in MySQL/MariaDB. π₯ **Consequences**: Remote attackers can execute **arbitrary code** via long parameters in the `GRANT FILE` command. Critical integrity loss!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper boundary checking in stack memory handling. π **CWE**: Stack-based buffer overflow (implied by description). The system fails to validate input length before copying to the stack.
Q3Who is affected? (Versions/Components)
π¦ **Affected Products**: Oracle MySQL & MariaDB. π **Versions**: MySQL 5.5.19, 5.1.53, and others. MariaDB 5.5.2.x (<5.5.28a), 5.3.x (<5.3.11), 5.2.x (<5.2.13), 5.1.x (<5.1.66).
Q4What can hackers do? (Privileges/Data)
π **Attacker Actions**: Execute **arbitrary code** on the target system. ποΈ **Privileges**: Likely requires authentication to use `GRANT FILE`, but leads to full system compromise if successful.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Medium. β οΈ Requires **remote authentication** and access to the `GRANT FILE` command. Not a zero-auth exploit, but dangerous if credentials are leaked.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exploit**: YES. π References: Exploit-DB #23075. π’ Disclosed on Full-disclosure mailing list (Dec 2012). PoC exists for Linux-based MySQL.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for specific MySQL/MariaDB versions listed above. π Check if `GRANT FILE` is enabled. Use vulnerability scanners detecting stack overflows in database services.
π§ **No Patch?**: Disable `GRANT FILE` privilege if possible. π Restrict network access to the database port. π§Ή Apply input validation at the application layer before sending commands to the DB.
Q10Is it urgent? (Priority Suggestion)
β‘ **Urgency**: HIGH. π¨ Remote Code Execution (RCE) is critical. Even though auth is needed, the impact is total system compromise. Patch immediately!
