An issue was discovered in Open Source Social Network (OSSN) through 5.3. A user-controlled file path with a weak cryptographic rand() can be used to read any file with the permissions of the webserver. This can lead to further compromise. The attacker must conduct a brute-force attack against the SiteKey to insert into a crafted URL for components/OssnComments/ossn_com.php and/or libraries/ossn.lib.upgrade.php.

Se detectó un problema en Open Source Social Network (OSSN) versiones hasta 5.3. Una ruta de archivo controlada por el usuario con una función rand() de criptografía débil puede ser utilizada para leer cualquier archivo con los permisos del servidor web. Esto puede conllevar a un mayor compromiso. El atacante debe dirigir un ataque de fuerza bruta contra el SiteKey para insertarlo en una URL diseñada para los archivos components/OssnComments/ossn_com.php y/o libraries/ossn.lib.upgrade.php.
