Users could overwrite configuration files (Option A ✅) Configuration files (e.g., my.cnf) contain crucial settings like authentication methods, storage engine configurations, and logging preferences.

Corrupt the database startup process. Data files could be deleted (Option B ✅) MySQL data files (.frm, .ibd, .MYD, .MYI, etc.) store critical database information. If unauthorized users have write access, they could: Delete important data or entire databases. Modify table structures to break applications. Corrupt files, leading to data loss or inconsistencies.

A and B

A. Configuration could be changed, but my.cnf is most likely not in it, but others. B. Data could be altered. D IS NOT CORRECT. Data injection is done over a connection, binaries ARE not affected since they are not in the datadir, startup doesn't change permissions.

A. Users could overwrite configuration files: If unauthorized users have write access to MySQL configuration files, they could modify them, potentially leading to misconfigurations that may compromise the security or stability of the database server. D. MySQL binaries could be damaged, deleted, or altered: Incorrect file privileges could allow unauthorized users to tamper with MySQL binary files, potentially damaging, deleting, or altering them. This could render the MySQL server inoperable or introduce malicious code.
