CVE-2020-10560

Name of the Vulnerable Software and Affected Versions Open Source Social Network (OSSN) versions through 5.3

Description An issue was discovered in Open Source Social Network (OSSN) where 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.

Recommendations For Open Source Social Network (OSSN) versions through 5.3, consider disabling access to the components/OssnComments/ossn com.php and libraries/ossn.lib.upgrade.php files until a patch is available. Restrict access to the SiteKey to minimize the risk of exploitation. Avoid using user-controlled file paths to prevent potential abuse. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
